I'm getting frustrated trying to build midididings.

I tried following @stefets wiki but I'm becoming confused....

I get these warnings during the build:

Hi!

I can't really help you but I would ldd the .so file to check if there is someting broken in it

Try :

ldd /usr/local/lib/python3.9/dist-packages/mididings-2015+rbbec99a-py3.9-linux-x86_64.egg/_mididings.cpython-39-x86_64-linux-gnu.so

Check the output if there is broken links.

Also, if you dont want to mess your system, create a python virtual environment, activate it and do all the pip and build stuff
