pip install pycddlib failed

[S-kewen]

Hi, first of all thank you very much for your contribution.

I recently tried to install pycddlib in ubuntu, but I found that the official website document does not include conda install, I tried using conda install -c conda-forge gmp && conda install -c anaconda gmp, but it still fails.

So, I would like to ask if it is possible to use the conda command instead of the following command: apt-get install libgmp-dev python3-dev

here is the errormsg (I guess it's caused by missing libgmp-dev): `Collecting pycddlib Using cached pycddlib-2.1.6.tar.gz (159 kB) Preparing metadata (setup.py) ... done Building wheels for collected packages: pycddlib Building wheel for pycddlib (setup.py) ... error error: subprocess-exited-with-error

I tried to execute the following command successfully in python 3.9.13: conda install -c conda-forge gmp && pip install pycddlib

But this method doesn't work in python 3.7.13. QAQ!!

It appears that the python install command is not finding the gmp headers installed by conda. I wish I could help, however I don't know much about conda. A quick search showed this on stackoverflow (different package but same problem):

https://stackoverflow.com/questions/43625797/how-should-conda-handle-header-files

It appears that conda install gcc to ensure conda uses its own gcc compiler rather than the system one somehow solved this for the poster: I guess because the conda installed gcc will find headers of packages installed by conda. If you manage to make it work, do let me know. Good luck!

Thanks for your quick reply, but I found that my above method works fine in python3.9.13.

So i think have any version compatibility issues between gmp and python and pycddlib?

I don't think so, since it works on Python 3.7 outside of conda, therefore the problem seems conda specific. Can you ask for help with the conda community?
