CommonQt for Qt5

This is a version of CommonQt adapted for Qt5. It uses the same package names as the original CommonQt for Qt4, therefore the two cannot be loaded simultaneously.

Building CommonQt on Windows

Initial Setup

  1. Ensure you have the following tools accessible via PATH (https://doc.qt.io/qt-5/windows-requirements.html):
* jom (1.1.3 works)
* ninja (v1.10.2 works)
* Ruby (2.7.3 works)
* Python 2.7
* bison and flex 2.5.5
* gnuwin32
* GPerf
* xmlstarlet 1.6.1
* Visual Studio 2019 Community edition

  1. Make sure the directory that contains win_bison.exe and win_flex.exe has priority over gnuwin32 in the PATH environment variable.

  2. Copy or rename win_bison.exe and win_flex.exe to bison.exe and flex.exe.

  3. Add the qt-install\bin directory to the beginning of the PATH environment variable, it's where moc.exe and Qt's DLLs are installed.

Compiling Non-Lisp Dependencies

Every project listed below should be compiled using "x64 Native Tools Command Prompt for VS 2019" cmd.

llvm

msbuild INSTALL.vcxproj -maxcpucount:4 /p:Configuration=Release

Notes

  • CMAKE_INSTALL_PREFIX and -prefix (for compiling qtbase) indicate the installation directory. Ensure that all those directories are included in the PATH environment variable.

  • Compiling LLVM takes several GB of space, ensure that there is at least 30GB of free space.

  • The configure step of qtbase will set the definitions for all other Qt projects.

  • Every project must be compile in the same configuration: DEBUG or RELEASE.

  • Qt, LLVM and smokegen must be compiled in RELEASE mode. The reason why is that Qt5 on windows differentiate the debug vs release dlls by a suffix letter, e.g. Qt5Core.dll (release) vs Qt5Cored.dll (debug). smokegen and smokeqt are not capable of coping with such difference. When migrating to Qt6, this will not be a problem as the suffix letter was dropped.

  • While compiling LLVM openmp, an error about "setlocal" and missing copy files may occur. To work around it:

    • Go to llvm-project\build\bin\Debug and move libomp.dll to llvm-project\build\bin\;
    • Go to llvm-project\build\lib\Debug and move libomp.dll.lib to llvm-project\build\lib;
    • Go to llvm-project\build\lib\Debug and move libomp.lib to llvm-project\build\lib;
    • Run build Again

  • Visual Studio 2019.8.1 has a bug (microsoft/STL#1300) that can be fixed using this patch:

    • Go to C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.28.29333\include and back up files intrin.h and intrin0.h.
    • git apply --unsafe-paths -p6 --directory="C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.28.29333\include" vs2019.8.1.diff

TODO: The qt-libs project has not yet been adapted to commonqt5.
