Cannot find <Python.h> on Debian 12 (bookworm)

[Sven Wehrend]

Hi there,

I've updated my system from Debian bullseye where I could successfully compile kicad, bnut had severe space issues to bookworm, in the hope that it would 

ease the kicad compiling. Sadly, I was not right, now I am confronted with this error:

[ 18%] Built target s3d_plugin_vrml

Despite, python3 and python3-dev being installed. I dont really understand the issue. This is on branch 8.0 ...

Any help appreciated.

Best,

Sven

Usually, this means that your development environment is not correctly configured.

The easiest way to fix it is to delete your build directory and start fresh.

Alternatively, you can run `ccmake` in your build directory and manually update the python directories.  My guess is that bookworm uses python3.11 and bullseye used python3.9, so the directories still point to the old location

And install the python-is-python3 package.

Thanks for the advice it seems to run  now.

And I want to excuse the "dumb" questions, its a while since I compiled software on a regular base, so I became a bit rusty... 

Best,
