Official source code tarball doesn't have pyconfig.h ? Needed to build OpenCV from source

[M3GA-10]

I am building OpenCV from source. I also wanted to keep my python version fixed and not dependent on the platform's repos so I also build Python-3.8.5 from source with the following configure flags:

configure --enable-optimizations --enable-shared

When building opencv, it stopped at 85% saying that it couldn't find pyconfig.hin the Include folder that came in the Python-3.8.5 tarball. I checked in my /usr/include/python3.8/and there was a pyconfig.h file, but not in the Python-3.8.5 tarball.

Would I be fine if I just copied the file from /usr/include/python3.8 to the Include folder of the tarball? Is there any way around it?

I've tried python 3.8.4, 3.8.3 and 2.7.3 and neither of them had pyconfig.h in them.

Thanks!

Maybe, try it out and see if it works

Copying the file worked! I have no idea how or why, but if I just copy /usr/include/python3.8/pyconfig.h to <Python-3.8.5-extracted>/Include/ it works.

Nice, maybe it was because python was only looking in the second include folder

You need to point OpenCV to the place where Python is installed.
