Glad fails on Windows with Python 3.9

[Janrupf]

Running Glad via CMake (Generator Ninja) yields the following crash:

Generating with args --out-path C:/Projects/MathAnimation/cmake-build-debug/Animations/vendor/gladsources/glad --api gl:core=4.2 c

Thanks, this slipped through the cracks in testing.

I can second this bug. I just tried to build glad2 into a static library. Here is my toolchain IDE: CLion Compiler: mingw64 9.0 Cmake: 3.24 OS: Windows 10, latest SR

The errors @Janrupf is getting are exactly the same as the ones I get.

[Janrupf]

Should be fixed by now, are you getting this with the latest glad2 commit? https://github.com/Dav1dde/glad/commit/e576e95d95ad407084f61ec02e1d3823d7b06c9f fixed it for me

i updated the repository but i am getting another error now:

    from jinja2 import Environment, ChoiceLoader, PackageLoader
ModuleNotFoundError: No module named 'jinja2'

Seems to be, that my python installation is missing "jinja2"

[Dav1dde]

@Tremah yes, glad2 does require jinja2.

I usually recommend to not integrate glad into the build process of your binary but instead just include pre-generated headers and source files. Less dependencies and faster compilations.

@Dav1dde The python installation was corrupt, for whatever reason. It has been working fine now. I made a small custom CmakeLists.txt and it works very smooth. Thanks for this library and all your effort!
