Qt5 Windows compilation with Mingw fails on qvkgen_wrapper.sh execution

SebastianM

Hi,

Windows 10, Qt 5.15.1, mingw 8.1 64b
Strawberry Perl and cygwin64 installed

where g++

c:\Qt\Tools\mingw810_64\bin\g++.exe
C:\Strawberry\c\bin\g++.exe

When Strawberry g++ was first - compilation ended with internal compiler error.

configure -debug-and-release -opensource -confirm-license -shared -platform win32-g++ -nomake examples -nomake tests -no-compile-examples -no-vulkan

Now, when I trigger compilation it fails with

mingw32-make[3]: Entering directory 'C:/Qt/5.15.1/Src/qtbase/src/gui'
C:/Qt/Tools/mingw810_64/bin/mingw32-make -f Makefile.Release all

I'm on Windows without shell. Why it executes qvkgen_wrapper.sh ?
I found this part in qtbase/src/gui/Makefile for vulkan files.

Someone mentioned in https://bugreports.qt.io/browse/QTBUG-66435 about similar problem which was supposed to not appear any more since 5.12.

How to complete successfully compilation?

Can you check whether you've sh.exe in the PATH? If so, qmake will assume you're running inside it, and will assume a shell environment.

Hi,
Yes, sh was accessible in PATH. I renamed cygwin64 folder, configured and build whole Qt without problem.
Thank you
