can't run setup , something to do with bjoern?

[oknoote]

Sorry a bit of a noob here when it comes to python but when I run $ sudo python3 setup.py develop I get the following error followed by a stacktrace:

  error: subprocess-exited-with-error

  × python setup.py bdist_wheel did not run successfully.

Try sudo apt install libev-dev

Hi @jackw01 ,

thanks for helping out.

I'm running into a a whole different kind of error this time unfortunately.. I upgraded to a RPI 4B and followed the installation instructions but now getting different errors running the setup.py script again. I'm running python 3.11.2.

Everything is going fine until running the setup.py script again, this time with a whole range of different errors:

$ sudo python setup.py develop
/usr/lib/python3/dist-packages/setuptools/installer.py:27: SetuptoolsDeprecationWarning: setuptools.installer is deprecated. Requirements should be satisfied by a PEP 517 installer.
  warnings.warn(
  error: subprocess-exited-with-error

  × python setup.py bdist_wheel did not run successfully.
  │ exit code: 1
  ╰─> [366 lines of output]

and then hundreds of lines of which I'll post the start here:

and so on.....

From what I can read out of this is that my gcc-compiler doesn't support mentioned flags, any other help from your end possible?

$ aarch64-linux-gnu-gcc --version outputs aarch64-linux-gnu-gcc (Debian 12.2.0-14) 12.2.0

Thanks...

Please try the latest commit in the master branch instead of the 2.1.0 tag.
