OS X codesign failed: bundle format is ambiguous (could be app or framework)

This error can be caused by many things but I know about one more which I didn't find anywhere else ;-).

In case you compile and deploy your app by using qtmacdeploy and sign your application immediately, everything will probably works fine. The problem occurs, when you need to copy your application to different location (for example during dmg building). In such cases, this error can occur:

bundle format is ambiguous (could be app or framework)<br />

Althought codesign is executed as always, singing isn't successful:

codesign --deep --force --verbose --sign &quot;$SIGNNAME&quot; ./Skipper.app<br />
/path/Skipper.app/Contents/Frameworks/QtCore.framework: bundle format is ambiguous (could be app or framework)<br />

The problem is, that during the copy it's necessary to keep all symbolic links inside frameworks. Without this, singing will fail.

So instead of

cp -r ./Source ./Destination<br />

it's necessary to use

cp -R ./Source ./Destination<br />

Qt Creator debugger doesn't work after last MacOS 10.9.4 update

Problem is caused by  lldbbridge.py file, where it's necessary to update few lines. After that, debugger will work like charm.

Qt5 application hangs-up when QNetworkAccessManager and QEventLoop is used on Mac OS

To be more specific, problem occurs only in very specific circumstances. It's in situation, when application is compiled as console-app and it's compiled on Mac OS X version older than 10.9:

CONFIG -= gui<br />
CONFIG -= console<br />

and when you're using QEventLoop::exec in mode processing all events except user events (QEventLoop::ExcludeUserInputEvents):

</p>
<p>//it's only demonstration, not full code...<br />
QNetworkAccessManager manager; ...<br />
QNetworkRequest request; ...<br />
QNetworkReply *reply = manager-&gt;post(request,arData);<br />
...</p>
<p>eventLoop.exec(QEventLoop::ExcludeUserInputEvents);<br />

In this situation, application hangs-up. When the application is compiled with GUI mode or when application is compiled on Linux/Windows (no matter if gui or console), everything works find. To fix this problem, it's necessary to implement hack similar to this (simplified version):

   bool bAllowUserInputEvents = false;</p>
<p>#if defined(PLATFORM_MACOS) &amp;&amp; defined(AX_APP_CONSOLE)<br />
   bAllowUserInputEvents = true;<br />
#endif</p>
<p>  if ( bAllowUserInputEvents == false )<br />
    eventLoop.exec(QEventLoop::ExcludeUserInputEvents);<br />
  else<br />
    eventLoop.exec(QEventLoop::AllEvents);<br />

How to change plist value on MacOS 10.9+

When .plist file is manually updated on MacOS 10.9+, changes are not directly applied to plist cache. This means that  these changes aren't visible to executed application (even if you run it after plist change).

It's necessary to tell plist change to reload this settings. There are two ways how to do it. First one is simpler but doesn't work if you completely remove .plist file:

defaults read ~/Library/Preferences/com.xxx.xxx.xxx<br />

Second method is much more efficient, but requires to completely kill plist cache. This cache is immediately executed again and during this launch all plist files are scanned and loaded again:

kill cfprefsd<br />

How to sign your Qt Mac OS X App for Gatekeeper

Starting from Mac os 10.8 apple applications requires certificate. Without that certificate (or without additional system tweaks described here on our product support page: http://support.orm-designer.com/5/macos-mountain-lion-10-8-unidentified-developer ) user will se following message:

&quot;OrmDesigner2&quot; can't be opened because it is from an unidentified developer.<br />

[caption id="" align="aligncenter" width="435"] MacOS unidentified developer in ORM Designer[/caption]

Solution

To solve this error message it's necessary to do following steps:

  1. Register in Apple developer program and pay $99 per year
  2. Download and install developer certificate
  3. Sign whole application
  4. Test it!

1) Register on Developer.apple.com

You need to create registration here: https://developer.apple.com/. It's necessary to fill info about contact person and company. After that, your registration will be reviewed by apple team and if everything will be OK, your registration will be approved.

**2) Use Apple site to generate certificates**

Open https://developer.apple.com/account/overview.action ,choose **Certificates, ** Click Add. Than select certificate parameters suitable for your need. In my case it was **Mac Development** and ** Developer ID.**

Now you need to install this certificate to your developer machine. Simply double-click on certificate and let system to import it. You can check that certificate is imported in **Go->Utilities->Keychain Access->login. **Now search for "Developer ID Application: XXXX"

MacOS certificate

**Note: **In my case when I transfer certificate to several developer machines I need to migrate also other Apple certificates. Without that my certificate wasn't a valid.

**3) Sign your application**

Now you need to sign your application including all plugins and frameworks inside app bundle. **After you sing your app, you can't do any changes in the bundle.** So as first run your deploy as usual and as **last step **do app singing.

For ORM Designer sign script looks like this:

#go to deploy directory<br />
cd $StarkDeploy.directory$/deploy</p>
<p>#sign app<br />
codesign --force --verify --verbose --sign &quot;Developer ID Application: Inventic s.r.o.&quot; ./OrmDesigner2.app</p>
<p>#sign all *.dylib files<br />
find OrmDesigner2.app -name *.dylib | xargs -I $ codesign --force --verify --verbose --sign &quot;Developer ID Application: Inventic s.r.o.&quot; $</p>
<p>#sign all Qt* frameworks<br />
find OrmDesigner2.app -name Qt* -type f | xargs -I $ codesign --force --verify --verbose --sign &quot;Developer ID Application: Inventic s.r.o.&quot; $<br />

4) Test it!

As last step it's necessary to test that sign process was successful. As first you can try following command line to validate  it:

codesign -vvv -d OrmDesigner2.app</p>
<p>#RESULT:<br />
Executable=/OrmDesigner2/DeployFiles/macos64/deploy/OrmDesigner2.app/Contents/MacOS/OrmDesigner2<br />
Identifier=com.orm-designer.OrmDesigner2<br />
Format=bundle with Mach-O thin (x86_64)<br />
CodeDirectory v=20100 size=174478 flags=0x0(none) hashes=8717+3 location=embedded<br />
Hash type=sha1 size=20<br />
CDHash=5a491e16f7dcca15b44af4XXXX1a2d2dcc786518<br />
Signature size=4237<br />
Authority=Developer ID Application: Inventic s.r.o. (6BYV46LH6T)<br />
Authority=Developer ID Certification Authority<br />
Authority=Apple Root CA<br />
Signed Time=6 Jun 2013 23:16:08<br />
Info.plist entries=10<br />
Sealed Resources rules=4 files=27<br />
Internal requirements count=1 size=212<br />

Now when you checked that App is correctly signed, it's time to try it on clean computer where no security policy changes was made. Upload your app and execute it.

If you don't see annoying screen "Can't execute application from unidentified developer", **you win** ;-).

Problem with Qt application on MacOS Retina display

Standard Qt application on retina display looks ugly. Fuzzy fonts and images. This is how ORM Designer originaly looks on Retina:

[caption id="" align="aligncenter" width="2880"] ORM Designer on Retina before optimizations[/caption]

Improve font autoscaling

First step how to improve Qt application on retina is by adding following definise to Info.plist

NSPrincipalClass<br />
NSApplication<br />

[caption id="" align="alignnone" width="405"] How to update Info.plist[/caption]

If you're updating existing application, it's necessary to copy application to different location after Info.plist update. MacOS cache all .plist files and without that update will not be apply.

After applying this fix, this is how application looks:

Qt #Qt #MacOs #Retina

Qt and Google breakpad Windows/Linux/MacOS

Integration of Google breakpad on any platform is really challenge. I didn't figure out how to do it by using recommended ways. So I did it my way ;-)

Create your own Qt project

As first thing I did when integrating Qt and Breakpad is creation of my own .pri file. I manually add all required files from Breakpad one-by-one, starting with src/platform/exception_handler continuing with all files included in previous ones. The complete .pri file you will find at end of this post.

After that I created simple CCrashHandler (inspired by qt-breakpad project) class which register exception handler. It's necessary to implement this handler for each platform separately because each platform have different parameters in google_breakpad::ExceptionHandler() constructor. CrashHandler source code you can find also at end of this post.

Using Breakpad on Linux:

Article about Linux integration.

Notes Linux

  • GCC 4.6.3
  • Ubuntu 12.04.1 32/64bit

Get and Compile Breakpad

#get breakpad latest version<br />
svn checkout http://google-breakpad.googlecode.com/svn/trunk/ google-breakpad-read-only</p>
<p>#compile all breakpad tools for extracting symbol files<br />
./configure<br />
make<br />
sudo make install</p>
<p>#when compilation is ready, you should have installed file dump_syms from original directory /src/tools/linux/dump_syms in your /usr/bin<br />
dump_syms<br />

Generate symbol file and test debug info

Now how to generate and use symbol file:

#generate .sym file<br />
dump_syms ./Application &gt; Application.sym</p>
<p>#store sym file in the correct location<br />
#this step is necessary. Without that minidump_stackwalk tool doesn't work</p>
<p>head -n1 Application.sym<br />
#Result: MODULE Linux x86_64 6EDC6ACDB282125843FD59DA9C81BD830 Application</p>
<p>mkdir -p ./symbols/Application/6EDC6ACDB282125843FD59DA9C81BD830<br />
mv Application.sym ./symbols/Application/6EDC6ACDB282125843FD59DA9C81BD830</p>
<p>#show stack with using minidump_stackwalk tool<br />
minidump_stackwalk ./crash.dmp ./symbols<br />

Result of minidump_stackwalk tool can look like this:

Use additional tools

There is script written by Mozzila corp which simplifies extracting and storing .sym file:
http://mxr.mozilla.org/mozilla-central/source/toolkit/crashreporter/tools/symbolstore.py?raw=1

Now with this script, you can do only one step instead of all described above.

python /path/to/script/symbolstore.py /usr/local/bin/dump_syms ./symbol-storage ./Application<br />

This command correctly creates folder Application/uuid in path symbol-storage and copy generated .sym file inside.

Using Breakpad on MacOS:

To integrate Breakpad and Qt on MacOS I used the same article as for Linux because I'm using gcc and linux-like development toolchain. For native XCode integration you have to probably use this article.

Notes MacOS

  • GCC 4.6.3
  • Qt creator toolchain
  • Mac OS 10.7.3 64bit
  • Don't using any of XCode tool chaing

Do almost all steps like on Linux integration. There is one exception, because you can't compile Breakpad tools using linux-like configure&make. You have to build these tools with XCode.

Compile google_breakpad/src/tools/mac/dump_syms/dump_syms.xcodeproj with XCode

Before I managed to successfully compile dump_syms in XCode, I have to update Architectures Debug/Release to 64-bit Intel and BaseSDK to "Latest Mac OS X". I also fix all issues displayed in the left part of XCode window.

Next step is change compilation type from Debug to Release. After a short searching I found a way in "Schema->Edit schema->Build configuration".

To be honest, I was not sure what I did, but it worked ;-). Maybe there is some easier way how to compile dump_syms in xcode, but I don't know how. This was my first contact with XCode ;-).

The application is compiled to path "/Users/User/Library/Developer/Xcode/DerivedData/dump_syms-bjvr/Build/Products/Release/dump_syms". Now copy dump_syms to safe location from where you will use it.

The rest steps are same like in the Linux.

Using Breakpad on Windows

Notes Windows

Article about Windows integration.

  • Compile with Visual Studio 2010
  • Post-mortem debugging is done also via VS2010
  • Google breakpad under windows generates common .dmp files which can by simply load directly to VS

Generate symbol files and test debug info

You have to choices for Windows. First option is use standard .PDB and .DMP files mechanism in VS. Second is use the same way how you can did it for Linux and Mac.

**First way**: Let compiler generate .PDB file. Store this files and use them later in VS together with your crash dump.

**Second way**: Use dump_sys.exe. This file is located in the google breakpad directory tree: google-breakpad\src\tools\windows\binaries\dump_syms.exe .

dump_syms.exe AtomixDevelopment.exe &gt;AtomixDevelopment.sym<br />

And also like under Linux, you can use Python script symbolstore.py to extract symbols to correct directory:

python.exe symbolstore.py binaries\dump_syms.exe .\Symbols AtomixDevelopment.exe<br />

Minidump stackwalk for windows:
http://code.google.com/p/pcxfirefox/source/browse/trunk/betterpgo/talos/talos/breakpad/win32/minidump_stackwalk.exe?r=19

The best thing at end

The most amazing thing I found about dump_syms is their platform independence. If you correctly extract symbol file on each platform and store it in one location, you can analyze any crashdump on one location. No matter what is source platform, you will analyze .dmp file by using **minidump_stackwalk ./crash.dmp ./symbols**.

How to include CrashHandler directly to your project

This is what I get when I follow all includes from **.h** and **.cpp** files starting with exception_handler.h for all platforms. With small modification you can include it to your project and your application will be fully breakpad-able ;-).

And this is the minimal implementation of your new CrashHandler. My ownd crash handler is much more sophisticate to perform reporting, sending crash dump etc. But for purposes of this article this is what you need (And also I don't want to share my whole know-how here ;-)))

QWidget: Must construct a QApplication before a QPaintDevice

Today I encounter this error after applying **macdeployqt** to my application. There is a lot of questions about this topic on google but not very answers.

The most important thing is setup following variable.

export DYLD_PRINT_LIBRARIES=1<br />

Using this you will se which libraries are loaded during execution of your application. The interesting thing is, that I see loading a libraries from their original directories instead of Application.app. But when I temporary moved these libraries from their location, libraries begin to load from then bundle location.

The reason for my "QWidget: Must construct a QApplication before a QPaintDevice" was executing an older version of QTitanRibbon from shared libraries path instead of the newest one compiled directly to /usr/lib.
The second reason for this issue was caused by another path in "export DYLD_LIBRARY_PATH". It seems that application search for libraries first in DYLD_LIBRARY_PATH and after in paths from their inner records.

To turn off this debug output, use:

unset DYLD_PRINT_LIBRARIES<br />

How to create nice MacOS DMG installer

In this article I will show how to create DMG installer in reusable way. The most of things and ideas presented here are ideas from several articles mentioned on the end of this article.

1) As first step we need to create our DMG template with link to Applications.
2) Next we have to modify the visual representation of DMG file.
3) Next we store created DMG as template
4) Now mount copied template as directory, fill DMG with real files
5) Detach mounted DMG, pack DMG
6) Distribute app ;-)

More detailed info about all these steps you will find in articles mentioned below. Here is a short script I wrote for three-phase deploying (1) create template, 2) pack template, 3)fill template with real data and compress it)

#! /bin/bash</p>
<p>TEMPLATE_DMG=atomix-development-template.dmg<br />
VOLUME_NAME=&quot;Atomix Development&quot;<br />
APPLICATION_FILE_NAME=&quot;AtomixDevelopment.app&quot;</p>
<p>if [ &quot;$1&quot; = &quot;create-template&quot; ]<br />
then<br />
  echo Create DMG template<br />
  mkdir template<br />
  cd template<br />
  mkdir $APPLICATION_FILE_NAME<br />
  touch $APPLICATION_FILE_NAME/fake<br />
  ln -s /Applications/ Applications<br />
  cd ..<br />
  rm $TEMPLATE_DMG<br />
  rm $TEMPLATE_DMG.bz2<br />
  hdiutil create -fs HFSX -layout SPUD -size 100m &quot;$TEMPLATE_DMG&quot; -srcfolder template -format UDRW -volname &quot;$VOLUME_NAME&quot; -quiet<br />
  rm -rf template<br />
elif [ &quot;$1&quot; = &quot;zip-template&quot; ]<br />
then<br />
  echo Zipping DMG template<br />
  bzip2 &quot;$TEMPLATE_DMG&quot;<br />
elif [ &quot;$1&quot; = &quot;create-dmg&quot; ]<br />
then<br />
  echo Creating DMG file from template and data</p>
<p>  #unzip template<br />
  rm $TEMPLATE_DMG<br />
  bunzip2 -k $TEMPLATE_DMG.bz2</p>
<p>  #create pack path and attach DMG<br />
  PACK_PATH=`pwd`/dmg-pack<br />
  mkdir $PACK_PATH<br />
  hdiutil attach &quot;$TEMPLATE_DMG&quot; -noautoopen -quiet -mountpoint &quot;$PACK_PATH&quot;</p>
<p>  #copy new content to DMG<br />
  cp -r &quot;$2&quot; &quot;$PACK_PATH&quot;<br />
  rm $PACK_PATH/$APPLICATION_FILE_NAME/fake</p>
<p>  #detach DMG, remove mount path<br />
  hdiutil detach &quot;$PACK_PATH&quot; -force -quiet<br />
  rm -rf $PACK_PATH</p>
<p>  #compress DMG<br />
  hdiutil convert -format UDZO -o tmp-packer-output.dmg &quot;$TEMPLATE_DMG&quot; -imagekey zlib-level=9<br />
  rm ./$TEMPLATE_DMG<br />
  mv ./tmp-packer-output.dmg $TEMPLATE_DMG</p>
<p>  #rm $TEMPLATE_DMG<br />
else<br />
  echo Missing parameter<br />
  echo &quot;create-dmg [create|zip-template|create-dmg Path/Application.app]&quot;<br />
fi<br />

So, it looks like that DMG file for ORM Designer2 is ready ;-)

Qt Mac OS #MacOs #deploy

How to deploy Qt application on MacOS - part II

In first part of this article I introduced a manual way how to deploy MacOS application. Because doing all these stuff manually was a lot of hand work, Qt introduced small tool called **macdeployqt**.

This utility looks very good, but also have some drawbacks. As first I will show you how utility works:

macdeployqt Application.app<br />

That's all ;-). This command should do all the hard work for you. But in some cases it didn't.

ERROR: no file at &quot;/usr/lib/libboost_iostreams.dylib&quot;<br />
ERROR: no file at &quot;/usr/lib/libboost_filesystem.dylib&quot;<br />
ERROR: no file at &quot;/usr/lib/libboost_system.dylib&quot;<br />
ERROR: no file at &quot;/usr/lib/libboost_thread.dylib&quot;<br />
ERROR: no file at &quot;/usr/lib/libboost_date_time.dylib&quot;<br />
ERROR: no file at &quot;/usr/lib/libboost_regex.dylib&quot;<br />
ERROR: no file at &quot;/usr/lib/libboost_chrono.dylib&quot;<br />
ERROR: no file at &quot;/usr/lib/libyaml-cpp.0.2.dylib&quot;<br />

The problem is that libraries mentioned in the previous list doesn't has included absolute path. If you inspecit this library, you will se this:

otool -L libboost_regex.dylib<br />
libboost_regex.dylib:<br />
	libboost_regex.dylib (compatibility version 0.0.0, current version 0.0.0)<br />
	/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 52.0.0)<br />
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 159.1.0)<br />

And this is the problem. Inner path in library is only filename without full path, so when we link library with our executable, our executable also has only relative path. And when macdeployqt try to find this library, automatically try to search in /usr/lib.

One possible solution is copy libraries to /usr/lib. Second solution is update paths in libraries to absolute paths. The third way is fix library linker to include full paths in libraries.

I found out that the simplies way how to fix it is call install_name_tool after library compilation and fix the path (don't forget to update library paths inside other library paths!)

  install_name_tool -id &quot;$SHL_PATH/boost/lib/libboost_chrono.dylib&quot; $SHL_PATH/boost/lib/libboost_chrono.dylib<br />
  install_name_tool -id &quot;$SHL_PATH/boost/lib/libboost_date_time.dylib&quot; $SHL_PATH/boost/lib/libboost_date_time.dylib<br />
  ...<br />
  install_name_tool -change &quot;libboost_system.dylib&quot; &quot;$SHL_PATH/boost/lib/libboost_system.dylib&quot; $SHL_PATH/boost/lib/libboost_chrono.dylib<br />
  install_name_tool -change &quot;libboost_system.dylib&quot; &quot;$SHL_PATH/boost/lib/libboost_system.dylib&quot; $SHL_PATH/boost/lib/libboost_filesystem.dylib<br />

So, now when we have updated all libraries, we can try to create application bundle again

macdeployqt AtomixDevelopment.app/<br />

And if we did everything correctly, now we should have a working app ;-).

Troubleshooting

In some cases you can get error "Permission defined", "Bad file descriptor" or other similar errors when using macdeployqt.

ERROR: &quot;install_name_tool: can't open input file: OrmDesigner2.app/Contents/Frameworks//libssl.1.0.0.dylib for writing (Permission denied)<br />
install_name_tool: can't lseek to offset: 0 in file: OrmDesigner2.app/Contents/Frameworks//libssl.1.0.0.dylib for writing (Bad file descriptor)<br />
install_name_tool: can't write new headers in file: OrmDesigner2.app/Contents/Frameworks//libssl.1.0.0.dylib (Bad file descriptor)<br />
install_name_tool: can't close written on input file: OrmDesigner2.app/Contents/Frameworks//libssl.1.0.0.dylib (Bad file descriptor)<br />

The reason is insufficient permissions for modifying copied libraries. Simple execute

sudo macdeployqt<br />

and everything should work ok. Another workaround for this issue is using newer version of Qt. I figured out that on MacOS I wrongly use Qt 4.7.4. When I correct this to version Qt 4.8.2 this issue was solved.

DMG file

If you want to create simply DMG file, simply call macdeployqt with param --dmg. But this dmg doesn't look so good:

This will need more investigation how to make DMG files nicer ;-).

Notes

  • Everytime you run macdeployqt run it on clean folder. The best way is to call rm -rf Application, compile app and than run macdeployqt

Notes to bug in macdeployqt

The problem is caused by invalid permissions. Copied libraries have the same permissions like in the source location. There are three different solutions:

  1. Use sudo and execute macdeployqt with root permissions
  2. Update external libraries permissions to rw, so also copies will have a correct permissions
  3. Update macdeployqt script. In file shared.cpp on line 91 is method copyFilePrintStatus. Here is a necessary to update copied files permissions to correct rw

In my case the problem was in file liblzma.5.dylib

Frameworks/liblzma.5.dylib is not writable (Permission denied)<br />

Orinal library is located in path:

/usr/local/Cellar/xz/5.0.4/lib<br />

Qt Mac OS #Qt #MacOs #deploy

How to deploy Qt application on MacOS - part I

As I wrote yesterday, I found the way how to proceed deployment on the Linux system. Today I have to manage it the same on the MacOS systems.

Note: the simplest way is introduced in the second part of this article.

The first usefull command for tracking dependencies between your application and other shared libraries is otool:

#path to executable, not .App directory!<br />
otool -L Application.app/Contents/MacOS/AppExecutable<br />

Now we can see paths to our libraries. The bad news is that MacOS doesn't have any -RPATH and $ORIGIN. The good news is utility install_name_tool and variable @executable_path which works similar like $ORIGIN.
Note: For newer versions of MacOS there are more variables like @executable_path. On version 10.4 was introduced @loader_path and on version 10.5 apple introduce @rpath variable.

The step-by-step solution

As first step it's necessary to upload all dependent libraries directly to the Application.app/Contents/MacOS/. For list all required files use otool:

cd Application.app/Contents/MacOS<br />
otool -L AppExecutable<br />

When we have copied all libraries, we need to change paths **for** and **in** all libraries.

Here is example how to set libxml2 library. As first step we will check how is library referred.

$user otool -L AtomixDevelopment</p>
<p>AtomixDevelopment:<br />
	libboost_iostreams.dylib (compatibility version 0.0.0, current version 0.0.0)<br />
	libboost_filesystem.dylib (compatibility version 0.0.0, current version 0.0.0)<br />
	/Users/User/dev/SharedLibraries/libxml/lib/libxml2.2.dylib (compatibility version 10.0.0, current version 10.8.0)<br />
	/Users/User/dev/SharedLibraries/libxslt/lib/libxslt.1.dylib (compatibility version 3.0.0, current version 3.26.0)<br />
	/Users/User/dev/SharedLibraries/libxslt/lib/libexslt.0.dylib (compatibility version 9.0.0, current version 9.15.0)<br />

And Library:

User$ otool -L libxml2.2.dylib<br />
libxml2.2.dylib:<br />
	/Users/User/dev/SharedLibraries/libxml/lib/libxml2.2.dylib (compatibility version 10.0.0, current version 10.8.0)<br />
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 159.1.0)<br />
	/usr/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.5)<br />
	/usr/lib/libiconv.2.dylib (compatibility version 7.0.0, current version 7.0.0)<br />

When we checked libxml2.2.dylib library with otool, we can see that library has hardocoded our development path. This isn't good ;-). So we now change this value to path relative to the executable and again verify this inner path.

install_name_tool -id &quot;@loader_path/libxml2.2.dylib&quot; libxml2.2.dylib<br />
otool -L libxml2.2.dylib<br />
libxml2.2.dylib:<br />
	@loader_path/libxml2.2.dylib (compatibility version 10.0.0, current version 10.8.0)<br />
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 159.1.0)<br />
	/usr/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.5)<br />
	/usr/lib/libiconv.2.dylib (compatibility version 7.0.0, current version 7.0.0)<br />

As you can see, now is path (first line) set up to reffer @loader_path/libxml2.2.dylib. It's correct now. As second step we have to update path in our executable, because also there is path hardcoded to our library repository.

install_name_tool -change &quot;/Users/User/dev/ExternalLibraries/../SharedLibraries/libxml/lib/libxml2.2.dylib&quot; &quot;@loader_path/libxml2.2.dylib&quot; AtomixDevelopment</p>
<p>otool -L AtomixDevelopment<br />
AtomixDevelopment:<br />
	libboost_iostreams.dylib (compatibility version 0.0.0, current version 0.0.0)<br />
	libboost_filesystem.dylib (compatibility version 0.0.0, current version 0.0.0)<br />
	@loader_path/libxml2.2.dylib (compatibility version 10.0.0, current version 10.8.0)<br />
        ...<br />

So, now we have changed also path in our executable. And now we need to do all these steps for all libraries..... ;-).

 

Notes

To follow the MacOS application convention it's better to place libraries to folder Application.app/Contents/Frameworks. Here is a directory schema for Qt example application plugAndPaint.

for fix simply change result_of::at_key to result_of::value_at_key

template &lt;class TNameParam&gt; typename fus::result_of::value_at_key&lt;TmapAssociations,TNameParam&gt;::type &amp; GetAssociationHolder()<br />

After fixing this error, you can achieved problem with const modifier. Correct syntax for const definition is:

template <typename TNameParam> typename fus::result_of::value_at_key<const TmapProperties,TNameParam>::type const & GetPropertyHolder() const
{ return fus::at_key<TNameParam>(m_mapProperties); }

How to deploy Qt application on MacOs

Missing dylib libraries

If your application using some externals dynamic libraries (called .dylib in MacOs system), you have to provide all these libraries. The simplest way is to provide these libraries into the Application.app directory.

Find out which libraries are used

Qt provide really useful tool called **"otool"** which serves to lots of purpose. One of them is to detect which shared libraries are required by our application. For this purpose otool has parameter -L. The usage is following:

otool -L ./Test1.app/Contents/MacOS/Test1<br />

Output could looks like this:

./Test1:<br />
        libboost_iostreams.dylib (compatibility version 0.0.0, current version 0.0.0)<br />
        libboost_filesystem.dylib (compatibility version 0.0.0, current version 0.0.0)<br />
        libboost_system.dylib (compatibility version 0.0.0, current version 0.0.0)<br />
        libboost_thread.dylib (compatibility version 0.0.0, current version 0.0.0)<br />
        libboost_date_time.dylib (compatibility version 0.0.0, current version 0.0.0)<br />
        libboost_regex.dylib (compatibility version 0.0.0, current version 0.0.0)<br />
        /Users/dev/dev/SharedLibraries/libiconv/lib/libiconv.2.dylib (compatibility version 8.0.0, current version 8.0.0)<br />
        /Users/dev/dev/ExternalLibraries/../SharedLibraries/libxml/lib/libxml2.2.dylib (compatibility version 10.0.0, current version 10.8.0)<br />
        /Users/dev/dev/ExternalLibraries/../SharedLibraries/libxslt/lib/libxslt.1.dylib (compatibility version 3.0.0, current version 3.26.0)<br />
        /Users/dev/dev/ExternalLibraries/../SharedLibraries/libxslt/lib/libexslt.0.dylib (compatibility version 9.0.0, current version 9.15.0)<br />
        /Users/dev/dev/ExternalLibraries/yaml-cpp-0.2.5/build/libyaml-cpp.0.2.dylib (compatibility version 0.2.0, current version 0.2.5)<br />
        QtGui.framework/Versions/4/QtGui (compatibility version 4.7.0, current version 4.7.0)<br />
        QtCore.framework/Versions/4/QtCore (compatibility version 4.7.0, current version 4.7.0)<br />
        /usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 7.9.0)<br />
        /usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 625.0.0)<br />
        /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.2.0)<br />

Output from "otool" is simmilar to linux tool "ldd".

The Mac Deployment Tool

Because manual copying and configuring all shared libraries to our application could be difficult, Qt have deployment tool which do all work for us. Tool is called "macdeployqt" and can be found in /Developer/Tools/Qt/macdeployqt.

 /Developer/Tools/Qt/macdeployqt ./GeneratedFilesMacOs/Debug/Test1.app<br />

**Note:** Every time when you call macdeployqt tool, project have to be build from scratch. But is sufficient when whole result directory is removed and linked again:

rm -rf ./GeneratedFilesMacOs/Debug/Test1.app/<br />
make<br />

TENG - c++ templating engine

Project site: http://teng.sourceforge.net/?page=home

External project documentation: http://teng.olmik.net/

Latest TENG source code: http://teng.cvs.sourceforge.net/teng/ (**Note**: Source code referenced from main site isn't latest! )

How to compile TENG on windows

Compilation under Windows is possible only using MinGW and with few modifications in TENG code (because there is few glitch which didn't meet c++ standards). If you want more information or updated TENG version, please let me know.

Mac OS problem with samba mount

Sometime after some time or when MacOS system is waked-up samba mounts stop working.

Instead of  mounting a drive reporting following error:

mount_smbfs: could not find mount point /mnt/disk_d: Socket is not connected&lt;/div&gt;<br />
mount_smbfs: could not find mount point /mnt/disk_e: Socket is not connected&lt;/div&gt;<br />
mount_smbfs: mount error: /mnt/disk_p: Socket is not connected&lt;/div&gt;<br />

After a little search I found following tip. It could help:

1. Click Start, and then click Run.<br />
2. Type regedit, and then click OK.<br />
3. Navigate to the following key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters<br />
4. In the right pane, double-click the IRPStackSize value.</p>
<p>NOTE: If the IRPStackSize value does not already exist, use the following procedure to create it:a. In the Parameters folder of the registry, right-click the right pane.<br />
b. Point to New, and then click DWord Value.<br />
c. Type IRPStackSize.</p>
<p>IMPORTANT: Type &quot;IRPStackSize&quot; exactly as it is displayed because the value name is case-sensitive. </p>
<p>5. Change the Base to decimal.<br />
6. In the Value Data box, type a value that is larger than the value that is listed. </p>
<p>If you created the IRPStackSize value using the procedure described in step 4, the default value is 15. It is recommended that you increase the value by 3. Therefore, if the previous value was 11, type 14, and then click OK.<br />
7. Close the Registry Editor.<br />
8. Restart the computer.<br />

Qt Linux #Qt #MacOs

Qt correct setup for QMAKESPEC, QTDIR and PATH

When you want to use different configurations for different platforms in your .pro file, it's necessary to correctly setup three variables: QMAKESPEC, QTDIR and PATH.

Here is how to configure for different platforms:

Microsoft Windows:

In SystemPropertes -> Enviroment variables add/update following values:

QTDIR = P:\QT\4.7.0<br />
PATH = %QTDIR%\bin<br />
QMAKESPEC=%QTDIR%\mkspecs\win32-msvc2005<br />
LANG = en_US<br />

Unix Bourne shell: (not tested)

QMAKESPEC=/usr/local/qt/mkspecs/linux-g++<br />
PATH=$PATH:/local/qmake/bin<br />
export QMAKESPEC PATH&lt;/pre&gt;<br />

Unix C shell: (not tested)

setenv QMAKESPEC /usr/local/qt/mkspecs/linux-g++<br />
setenv PATH $PATH:/local/qmake/bin&lt;/pre&gt;<br />

Note

You can optionally use LANG variable to setup QtCreator language.

Qt #Qt #MacOs #Linux #Windows

List of known issues and tips

This is list of all known issues and problems which we had to solve during our first Qt installation on Linux, Windows and Mac.

Known errors

Error: undefined interface

What to do when compilation of QT crash with message “Error: undefined interface”.
http://www.qtforum.org/article/31561/error-when-building-libraries.html
http://www.qtcentre.org/threads/26245-Qt-4.6-api/qscriptextensionplugin.h(43)-Error-Undefined-interface

make: g++: Command not found

it’s necessary to instal g++ support (sudo apt-get install g+)

Basic XLib functionality test failed!

it’s necessary to instal xlib(xorg??) support (sudo apt-get install xorg-dev)

*** [sub-corelib-make_default-ordered] Error 2

Probably mishmash on 32bit / 64bit  system and QT versions.

undefined reference to `QEventDispatcherGlib::versionSupported()’

Probably missing libglib2.0-dev on your system. (sudo apt-get install libglib2.0-dev).

Undefined reference to QSslSocket::*

Missing OpenSSL library on your system. (sudo apt-get install libssl-dev)

gtk/gtk.h: No such file or directory

Missing gtk package. (sudo apt-get install libgtk2.0-dev ). After that its necessary to update db (sudo updatedb).

if system can’t find file gtk/gtk.h because gtk is stored in gtk-2.0 directory, add -I (capitalised i) param to configure with gtk path:

 ./configure -opensource -I /usr/include/gtk-2.0 

cups/cups.h: No such file or directory

install libcups2. (sudo apt-get install libcups2-dev)

gst/gst.h: No such file or directory

install gstreamer 0.10. (sudo apt-get install libgstreamer0.10-dev)

Missing Include/glibconfig.h

it’s because this file isn’t in /usr/include/glib-2.0, but in /usr/lib/glib-2.0. So you have to include also this /usr/lib path or copy file to include/glib-2.0

Hints and tips

create symbolic link using **ln -nsf /usr/include/gtk-2.0/gtk /usr/include/gtk **

Minimal required libraries

List of libraries required by Qt:

  • libfontconfig1-dev
  • libfreetype6-dev
  • libx11-dev
  • libxcursor-dev
  • libxext-dev
  • libxfixes-dev
  • libxft-dev
  • libxi-dev
  • libxrandr-dev
  • libxrender-dev

And other which are required by some modules of Qt:

To install all required on Linux, use following commands

 sudo apt-get install libfontconfig1-dev libfreetype6-dev libx11-dev libxcursor-dev libxext-dev libxfixes-dev libxcups/cups.h: No such file or directory ft-dev libxi-dev libxrandr-dev libxrender-dev

sudo apt-get install bison flex libqt4-dev libqt4-opengl-dev libphonon-dev libicu-dev libsqlite3-dev libxext-dev libxrender-dev gperf libfontconfig1-dev libphonon-dev  

If error doesn’t disappear after installing correct library

Sometimes it’s necessary to reconfigure Qt using make confclean

How to find where is missing header file located on disk

Use find /path -iname xxx.h command

How to find package which contains missing header file

use apt-file application with following syntax:

 apt-file search gdk/gdk.h 

List of links about installation:
Building Qt on Linux

Qt configuration for succesfull build

This is currently my latest configure command to compile Qt on my Ubuntu 10.10.

Compilation fixes

This is necessary when search path for following libraries isn’t entered to configure.

 sudo ln -nsf /usr/include/gstreamer-0.10/gst /usr/include/gst 

Todo

Figure out how works pkg-config (pkg-config –cflags gstreamer-0.10)

Qt installation and configuration

This is our company step-by-step guide to install and configure Qt on our developer machines.

How to install Qt

Link to Qt download site: http://qt.nokia.com/downloads

Windows (VS2005)

Download VS 2008 distribution from download site. When 2008 distribution is downloaded, it’s necessary to reconfigure and rebuild it for VS 2005 using next steps.

Linux

Download linux/x11 distro from Qt page. Download 32/64bit distro package. Setup downloaded files as executables:

 chmod +x qt-sdk-linux-x86-opensource-2009.01.bin chmod +x qt-creator-linux-x86-opensource-1.0.0.bin 

Install Qt sdk to default directory and begin with configuration.

MacOS

Download latest Qt SDK distribution and latest XCode developer pack from apple site. Then install both.

How to configure Qt

Qt configuration is done via Configure script/executable on all platforms.

Windows

Run “Start menu->Visual studio->Tools-> Visual studio command prompt”
Then go to “c:\Qt\Qt_Version\Qt” and run “configure” with additional params.

Our current configuration:

 configure -debug-and-release -opensource -shared -platform win32-msvc2005 -incredibuild-xge -openssl  

Clean configurations

run nmake confclean and nmake distclean to remove all previous version of QT compilations.

SSL support

For SSL Support add -openssl switch to configure.

Note!

: configure param HAVE TO be executed from Visual studio command prompt!

Linux

Enter Qt directory and enter following configure param:

 ./configure -opensource -I /usr/include/gtk-2.0 -L /usr/lib/gt-2.0 -I /usr/include/gstreamer-0.10 -L /usr/lib/gstreamer-0.10 -I /usr/include/glib-2.0 -L /usr/lib/glib-2.0 -I /usr/include/libxml2 -fast  

Clean configurations

run make confclean and then configure.

MacOS

How to compile Qt

Windows

Compile Qt using command prompt:

  • Run Visual studio command prompt.
  • And run nmake to build a whole library

Second option is open projects.sln located in p:/Qt/4.7.1/ using Visual Studio IDE  and compile it.

Linux

  • As first thing, use configure to setup Qt settings.
  • As next, run make to build a whole library
  • After a while when everything is compiled, use make install. This will install library to /usr/local/Trolltech/Qt-4.7.0

MacOS

Currently not tested, using default compilation.

How to compile application

When we have prepared Qt library, it’s time to compile our application.

MacOS

When using  qmake without additional params, qmake generate xcode project from .pro instad makefile for g++. To generate makefile, use following params:

 qmake -spec macx-g++  
make
