GammaRay 3.1.0 on Windows for Qt 5.15 inspection

[zoell]

Hi Guys, I want to inspect an app that was built with Qt 5.15 so I built GammaRay 3.1.0 on Windows, but when I start the launcher and select my app to launch it starts GammaRay which starts my app and after that I guess it would start the client but the client gives a message after like 1-2 minutes that the connection was refused.

This is in the Qt Application Output tab:

08:54:27: Starting D:\GammaRayBuild\GammaRay\build\Desktop_Qt_5_15_0_MinGW_64_bit-Release\bin\gammaray-launcher.exe...

08:59:19: The command "D:\GammaRayBuild\GammaRay\build\Desktop_Qt_5_15_0_MinGW_64_bit-Release\bin\gammaray-launcher.exe" finished successfully.

For this I installed Qt 5.15 with MinGW and have the latest CMake. I tried the MSVC way but there were huge amount of issues and problems during build that I am unable to fix.

What I did to build is I checked out the code and switched to tag 3.1.0 and imported the CMakeLists.txt into Qt Creator and added the Release build config.

There was one issue I had to fix however. Qt has this file here:
Qt\5.15.0\mingw81_64\lib\cmake\Qt5AttributionsScannerTools\Qt5AttributionsScannerToolsConfig.cmake

And had some problems with this:

    set(imported_location "${_qt5_qattributionsscannertools_install_prefix}/bin/qtattributionsscanner")
    _qt5_AttributionsScannerTools_check_file_exists(${imported_location})

Since the qtattributionsscanner file is not there, so I changed that to qtattributionsscanner.exe and it allowed me to build.

Wondering what else I can try? Looks like GammaRay is not listening for some reason?

Hi,

Does gammaray work for you with a minimal main.cpp application, or just broken with your real application ?

[zoell]

Just tried it with a minimal cpp app, just a few lines of code, same issue.

Anything I can do to check this issue on my side? I really need to examine that Qt 5.15 app.

[iamsergio]

how big is your swap, and how much RAM ?

Page file is 8GB, RAM is 64GB.
