Could you tell me how to solve this problem? I have checked several websites, but there is no relevant solution.

I'm not sure what environment you're trying to build in.
But there's obviously a mismatch in the function signature in cyglfw and your version of GLFW3.
The code appears to still be in sync with GLFW 3.3.

How to solve this problem???

[BeiHaigogogo]

I also encountered the same problem, have you solved it?

[Zephyr-One]

The same problem. Have you solved it?

[zhaoxuefengeric]

I have just happend to solve this problem.

1. VERSION : use GLFW3.3.0 version. Just as the ahthor said, cyglfw3 3.1.0.2 appears to still be in sync with GLFW 3.3.
2. BUILD: when building GLFW3 mannually, make sure you use command like cmake -DBUILD_SHARED_LIB=ON .. to make it generate .so file. This is because cyglfw3 3.1.0.2 use -lglfw to indicate the library name. In CMakeList.txt with verision of GLFW3.3, if you generate dynamic library file, you can get libglfw.so, which is perfect with cyglfw3 3.1.0.2; but if you generate static library file, you will get libglfw3.a, which will cause errors when pip install cyglfw3.

BTW, I use cython==0.28.2 and setuptools==63.0.1
Hopefully, this could help
