pycddlib cannot be installed on MacOS Monterey M1

[ubayram]

The pycddlib installation problem cannot be resolved with the commands provided at the ReadMe unfortunately. I've done some digging at the github page of pycddlib and it seems like the currently available version (2.1.6) isn't compatible with MacOS. It seems like they experimented with new versions that are compatible (2.1.7a0) but aren't available to install yet. I've inferred all these information from the page https://github.com/mcmtroffaes/pycddlib/actions

So, how can we work around this issue and be able to install & test LNN regardless?

Currently running the code brew install gmp; env "CFLAGS=-I/usr/local/include -L/usr/local/lib" pip install pycddlib returns the following error:

Same issue. gmp is installed via brew without fault. gmp version 6.2.1_1

I think it might have something to do with folders. Location of gmp.h for me is here: /opt/homebrew/include/gmp.h

[sodoherty-ai]

This worked for me.

env "CFLAGS=-I/opt/homebrew/include -L/opt/homebrew/lib" pip install pycddlib

[ubayram]

This worked for me.

env "CFLAGS=-I/opt/homebrew/include -L/opt/homebrew/lib" pip install pycddlib

It worked!!! Thank you!!!
