Question / Help OBS 23.1.0 fails to Install on Debian 9 Testing/Buster Fatal error: Python.h: No such file or directory

[dannysupernova]

Update: I was able to install OBS 23.0.2 just fine. This only happens on OBS 23.1.0.

So long story short, my HDD died yesterday, and my OS was installed on it. I had OBS running just fine on Debian 9 only a few days ago. I don't recall what version OBS (sorry). So I got a new SSD today, and installed Debian 9 Stable/Stretch. OBS would not install, so I decided to try Debian 9 Testing/Buster. Still nothing. Here's what I'm getting during make -j4 step.

I have python3-dev installed, and it's version 7. Perhaps I'm missing a symlink somewhere? I know I've had to create symlinks for stuff for OBS before, but this error is a bit more cryptic for me. Any help would be appreciated. Thanks in advance.

Python.h: No such file or directory # include <Python.h>

Most of the time these are dependency-issues. Python.h is used by GNU Compiler Collection (gcc) to build applications. You need to install a package called python-dev for building Python modules, extending the Python interpreter or embedding Python in applications. You encounter "Python.h: No such file or directory" error while trying to build a shared library using the file extension of another language ( e.g. 'C' ). If you are trying to build a shared library using the file extension of another language, you need to install the correct development version of Python.

Reason for this error:

• You haven't properly installed the header files and static libraries for python dev.
• Also, sometimes include files might not be default in the include path.

How to solve this error:

• Install the missing files and libraries.
• Include Path and Library.
• Finally, Compile it.
