Re: [Interest] Qt 5.6.2 Git on Windows: -force-debug-info configure option triggers linker warning on usage

This is a bug.

 

Try to use this patch and tell me if it works for you:

diff --git a/qmake/generators/win32/msvc_nmake.cpp b/qmake/generators/win32/msvc_nmake.cpp

Betreff: [Interest] Qt 5.6.2 Git on Windows: -force-debug-info configure option triggers linker warning on usage

I checked out Qt 5.6.2 from the git repository and configured it with

 

..\configure -prefix "%DESTINATION_DIR%" -release -force-debug-info [...]

 

Qt configures, builds and installs ok, but when using the result in a project, I get this linker warning for every executable using Qt:

 

qtmain.lib(qtmain_win.obj) : warning LNK4099: PDB 'qtmain.vc.pdb' was not found with 'qtmain.lib(qtmain_win.obj)' or at 'L:\SVN_Work\source\mb\BIN\Release_x64\qtmain.vc.pdb'; linking object as if no debug info

 

​I found the file in (builddir)\qtbase\src\​winmain\.obj\release but it does not get copied to the installation directory.

​Is this a bug / missing feature of the Qt build process or am I doing things wrong?​
