[I had the same problem on Arch Linux](https://aur.archlinux.org/packages/hplip-3.18/#comment-724715), and a solution was to add the output of `python-config --includes` to the `CFLAGS` before invoking `./configure`, e.g. to add CFLAGS+=" $(python-config --includes)" export CFLAGS to the script which does the compilation. `python-config --includes` returns, on my machine, `-I/usr/include/python3.8 -I/usr/include/python3.8`, and more special versions of it are `python3-config --includes` and `python3.8-config --includes`.

Should be fixed in Git. Please reopen if there are still issues.
