Running example 'widgets\graphicsview\boxes' under windows7, needs '-opengl desktop' error

@TopDoozer said in Running example 'widgets\graphicsview\boxes' under windows7, needs '-opengl desktop' error:

Do i need to revert anything before i run configure and mingw32-make again?

You should start from clean state. Best is to use out of source builds.

[TopDoozer]

OK. So i now created a 'build' folder. Opened a console in that folder and called configure.bat from there. This is the configure.log file:

Command line: -prefix d:\Qt\Qt5.12.3\build -opengl desktop -nomake tests

I do have a configure.log file.... but i cannot upload it and its toolong to post in toto.
There are a couple of configure tests that fail:

executing config test alloca_h

• cd /d D:\Qt\Qt5.12.3\build\config.tests\alloca_h && D:\Qt\Qt5.12.3\build\qtbase\bin\qmake.exe "CONFIG -= qt debug_and_release app_bundle lib_bundle" "CONFIG += shared warn_off console single_arch" D:/Qt/Qt5.12.3/build/config.tests/alloca_h
• cd /d D:\Qt\Qt5.12.3\build\config.tests\alloca_h && set MAKEFLAGS=& mingw32-make

is the first one...

@TopDoozer Failing tests are normal. The question is: is any feature you need disabled because of failing tests? If not then just build.

[TopDoozer]

@jsulm are you suggesting, that build might fail if i try to run it with a feature that might not have passed the configure test (running nmake right now but expecting it to fail again)?

[jsulm]

@TopDoozer No, it should not fail, but some features will not be built.

[TopDoozer]

i ran nmake with this result:

[TopDoozer]

Any idea whats going on, or what i am missing? Anything i can do to provide more information to gain insight into the error?

[TopDoozer]

Tried to keep it simple and just ran configure followed by nmake. Same error: Unknown module in Qt: bootstrap-private. WTF?

[TopDoozer]

Tried something else again. went and ran configure in the source directory (Command line: -prefix d:\Qt\Qt5.12.3\build2 -opengl desktop -nomake tests -nomake examples). Then i ran mingw32-make in the Source folder. Thats what i got:

Anyone any idea, what the hell is going on here? I am starting to think Qt might not be worth it anymore trying to get back into, which would be fine crying shame!

@TopDoozer Which version of MinGW do you use to compile?
