[OpenWrt-Devel] Package compile which requires Python.h

[Alexandru Ardelean]

Yep, seen this a couple of times.

You're building for an x86 target, but you're including the host Python's
Python.h file.
Any idea why this happens ? Or if you're include paths are ok ?

It could also [very likely] be a regression with the Python package.
If you want, you could show me your Makefile and I can try to figure out
what's wrong.

An example of a Python package that builds as  C extension is this:

Here's a similar issue [a Github link] which is closed:

Cheers
