在使用QML的项目中使用调试符号从VS 2017的源代码构建Qt的正确配置是什么？

Question

I'm having issues trying to build Qt such that I can get the debug symbols to figure out why the application crashes every few days or so. This is for a 64 bit qml application with c++ feeding data from a worker thread. This is a full screen (with on screen keyboard) application that runs on windows. Below is the output from config.log with the command given in the first line. I've X'ed all personal info. What would cause the error shown in the last 2 lines?

Command line: -platform win32-msvc2017 -commercial -prefix win32-msvc2017 -confirm-license -debug-and-release -force-debug-info -nomake examples -nomake tests -skip qtwebengine -skip qt3d

Answer 1

If you were using a precompiled Qt SDK for VS2017, then there is no reason to recompile Qt only for getting debug files.

Starting with Qt5.12, debug files (*.pdb) are available for download with the online installer. Just check this option when installing:

Your PATH doesn't include the location of the "rc.exe" program (the resource compiler). If you type in the same cmd.exe window the command "where rc.exe" it would say that the file could not be found.

You should call "vcvarsall.bat" to prepare the environment for the compiler and the tools. For instance:

C:\Qt\5.12.5\msvc2017_64>call "C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\VC\Auxiliary\Build\vcvarsall.bat" x64
