Could not find the Qt platform plugin “xcb” in “”
Full error code:
Library searching paths: - /home/dev/dev/SharedLibraries/qt/plugins qt.qpa.plugin: Could not find the Qt platform plugin "xcb" in "" This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem. Available platform plugins are: linuxfb, minimal, offscreen, vnc.
The reason is that libqxcb.so really missing in the plugins directory. It’s because Qt compilation issue.
It’s necessary to install:
sudo apt-get install libclang-dev #XCB sudo apt-get -y install "^libxcb.*" libx11-xcb-dev libglu1-mesa-dev libxrender-dev sudo apt-get -y install libxkbcommon-dev libxkbcommon-x11-dev sudo apt-get -y install libfontconfig1-dev libfreetype6-dev libx11-dev libxext-dev libxfixes-dev libxi-dev libxrender-dev libxcb1-dev libx11-xcb-dev libxcb-glx0-dev sudo apt-get -y install libxcb-keysyms1-dev libxcb-image0-dev libxcb-shm0-dev libxcb-icccm4-dev libxcb-sync0-dev libxcb-xfixes0-dev libxcb-shape0-dev libxcb-randr0-dev libxcb-render-util0-dev sudo apt-get install libxcb-devel libxkbcommon-devel xcb-util-devel xcb-util-image-devel xcb-util-keysyms-devel xcb-util-renderutil-devel xcb-util-wm-devel mesa-libGL-devel #D-Bus sudo apt-get install libdbus-1-dev libdbus-glib-1-dev libx11-dev
Note:
It’s necessary to install also correct xinerama packages and dev packages: https://packages.ubuntu.com/search?keywords=xinerama
Google breakpad 2020
Get breakpad
git clone https://chromium.googlesource.com/breakpad/breakpad git clone https://chromium.googlesource.com/external/gyp
Prepare windows
gyp\gyp.bat --no-circular-check breakpad\src\tools\windows\tools_windows.gyp gyp\gyp.bat --no-circular-check src\client\windows\breakpad_client.gyp
Prepare linux
- add src/third_party/lss/linux_syscall_support.h
Fix few things in VS studio in tools_windows
– library output from $(OutDir)lib\$(ProjectName).lib to $(OutDir)\$(ProjectName).lib
– add missing dependency lib Pathcch.lib
– unload gtest, gmock and dump_syms_unittest
Fix few things in VS studio in breakpad_client
– library output from $(OutDir)lib\$(ProjectName).lib to $(OutDir)\$(ProjectName).lib
– unload all unittests projects
– for crash_Generation_client, crash_generation_server, exception_handler, common, crash_generation_app
– c++ -> language -> enable RTTI YES
– c++ -> codegeneration ->runtime library -> MD/MDd
How to extract symbols
The simplest way is to use
dump_syms.exe APP_PATH\APP.exe > app.sym
but this doesn’t prepare correct structure for automatic dmp file evaluation, so we need to use symbolstore.py

Notarized Qt binaries for OSX
Notarization sh script for automate whole process. Script is created based on several examples found on the web. Links to these examples can be found bellow (mostly thanks to Logcg.com blog).

How to generate new Apple developer certificate
“KeyChain Access application” -> KeyChain access -> Certificate assistant -> Request certificate from authority
- Save the certificate request to disk.
- Open website https://developer.apple.com/account/mac/certificate/distribution/create
- MacOS -> Developer ID
- Developer application -> Next -> Next
- Upoad request file, download generated certificate
- Doubleclick on certificate and import it to Keychain access
Usage
For the first time it’s necessary to use codesign from the OSX directly, not via putty/remote.
Execute
codesign --deep --force --verify --sign "$SIGNNAME" --options "runtime" $APP
and enter keychains passwords and confirm with “Always use” . Next time you can use putty as usual.

Incredibuild and “cannot create temporary il file”
This is caused by latest MS security update. After applying these two 3126587 and 3126593 previous versions of Incredibuild stopped working.
Command line error D8037 : cannot create temporary il file
The solution is to uninstall it
https://support.microsoft.com/en-us/kb/3126587
https://support.microsoft.com/en-us/kb/3126593
On Windows 10 the responsible update is KB3135173
Next steps
Also it’s necessary to disable these updates in auto-update!
