Process is not injecting to GammaRay with MingW

[SUBRBHCONT]

Setup: Qt 6.2.4
Cmake: 3.24.2

I have took the latest GammaRay code and tried building with Mingw compiler. The build was successful. But When I tried running the Gammaray Launcher getting the below error:

Startup: gammaray-launcher
Qt Assistant not found in QT_INSTALL_BINS. Looking in standard Path next.
gammaray.qhc not found in "C:/Mahindra/GammaRay/build-GammaRay-Desktop_Qt_6_2_4_MinGW_64_bit-Debug/bin\..//share/doc/GammaRay" - help not available

Working Directory: C:/Users/ZBHA1KOR/Desktop/build-test2-Desktop_Qt_6_2_4_MinGW_64_bit-Debug

Do guide if I doing anything wrong here or any other additional setup or env paths need to be set for running the Gammaray Launcher. Thanks for the support in advance.

How did you build gammaray? Can you share the cmake command used to configure?

> Option GAMMARAY_QT6_BUILD, Build with Qt6.

Not sure if it will make a difference but can you try to enable GAMMARAY_QT6_BUILD and see if it changes anything.

Besides that, can you use a debugger to see what's happening? Perhaps GammaRay is crashing or something else.

[gitqic]

Same here. The GammaRay built with Qt6 MinGW crashes when trying to attach a program. However, the GammaRay built with Qt6 MSVC 2019 works.

CMake command I used is (using msvc command prompt):

cmake . -B build_msvc -DCMAKE_INSTALL_PREFIX=C:/Tools/gammaray_msvc -DCMAKE_PREFIX_PATH=c:/Qt/6.5.0/msvc2019_64 -DGAMMARAY_QT6_BUILD:BOOL=ON -DQMLLINT_IS_WORKING:BOOL=OFF

A workaround has to be applied to avoid the qmllint issue, which is mentioned here: #781

Comment out qml_lint(mapview.qml) in GammaRay/plugins/positioning/CMakeLists.txt (line 49)

seems duplicate of #959
