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

2 comments

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)

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

codesign --deep --force --verbose --sign "$SIGNNAME" ./Skipper.app
/path/Skipper.app/Contents/Frameworks/QtCore.framework: bundle format is ambiguous (could be app or framework)

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

it’s necessary to use

cp -R ./Source ./Destination

QDialog::reject can be invoked multiple times

Leave a comment

When user use ESC to close the dialog and press it very quickly two or more times in a row, QDialog::reject can be invoked also multiple times.

This is very dangerous and unpredictable because in case your reject will contain some one-time-execute routine the application will start crashing.

The only solution I found is to add these routines to QDialog destructor instead of to reject/accept.

Everything is perfectly explained in this post:

List of commands

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update; sudo apt-get install gcc-4.8 g++-4.8
sudo update-alternatives --remove-all gcc 
sudo update-alternatives --remove-all g++
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 20

sudo update-alternatives --config gcc
sudo update-alternatives --config g++
gcc --version

Starting with OS X 10.10 existing code signing method doesn’t work. If you have application signed for 10.9 and application works without problems, with 10.10 you will get following error:

How to verify application sign status from command line:

codesign -dvvv /Applications/APP.app

Executable=/Applications/Skipper.app/Contents/MacOS/Skipper
Identifier=com.skipper.Skipper
Format=bundle with Mach-O thin (x86_64)
CodeDirectory v=20100 size=239848 flags=0x0(none) hashes=11986+3 location=embedded
Hash type=sha1 size=20
CDHash=98839e7aa72de4105ac5ad8a2612682ba3bca53f
Signature size=4237
Authority=Developer ID Application: Inventic s.r.o. (6BYV46LH6T)
Authority=Developer ID Certification Authority
Authority=Apple Root CA
Signed Time=03 Feb 2015 17:38:21
Info.plist entries=10
TeamIdentifier=not set
Sealed Resources version=1 rules=4 files=44
Internal requirements count=1 size=300

As it’s seems from the verification output, application is correctly signed but OSX doesn’t accept it. Another way how to verify application sign status is via spctl command:

spctl --assess --type execute --verbose Skipper.app/

Skipper.app/: rejected
source=obsolete resource envelope

We have some error at least. Now it’s necessary to find out what is wrong. We can try one more test:

codesign -v Skipper.app/
Skipper.app/: resource envelope is obsolete (version 1 signature)

where we dest little bit more details. All these errors we get only on 10.10 mac, not on 10.9 or older.

After another investigation I found following article. The most important part is:

“Important: For your apps to run on updated versions of OSX they must be signed on OS X version 10.9 or later and thus have a version 2 signature.”

Another post about this topic is in felix-schwarz.org blog.

So ,it’s bad. We need to update our build machine to 10.9 or at least create new “sign machine” and make sure that everything will work as expected.

edit file sudoers

sudo nano /etc/sudoers

or

sudo visudo

and modify

%sudo ALL=(ALL) ALL

to

%sudo ALL=(ALL) NOPASSWD: ALL

and add following line to the end of the file:

user ALL=NOPASSWD: ALL

Be careful!

When editing sudoers, it’s necessary to be very careful. Any error cause that you will not be able to edit this file anymore and also not to use sudo ;-).

Here are links how to fix it (verified 😉 )
