Is it planned to build pythonocc-core for linux-arm64 ?

[Spoutnik97]

I would like to install the library on a docker image build with my Macbook Pro M3.
Currently, the conda installer does not find pythonocc-7.7.2 because it is not available on conda-forge.

Should possible to build the library for linux-arm64 ? Or is there another solution ?
I could build it myself, but if the need is shared by someone else, we could share ressources and time

there are binaries for osx-arm64 on conda, but not linux-arm64. I don't know if there are plans on the conda-forge side to provide linux-arm64 packages. You can try it by yourself and report here your results. I think that the pythonocc-binderhub docker file is a good place for you to start with https://github.com/tpaviot/pythonocc-binderhub/blob/build-master/Dockerfile

Hi @tpaviot !
I tried to build the docker image. It works !

But the last command failed while executing python tests

Any idea where this could come from?

I will test the OCCT compiled lib to see if it seems ok, and will keep you informed

@jenkoj what do you exactly mean with "7.8.1 seems to be corrupt"? Can you please post the full trace when installing 7.8.1 from conda-forge channel?

[tpaviot]

ModuleNotFoundError: No module named 'OCC'

@jenkoj that means pythonocc is not installed in a known python path

@tpaviot and @Spoutnik97, my mistake. I thought docker on M2 was using osx-arm64 and not linux-arm64. So please ignore my Dockerfile above. While it does install and import the package, the precompiled binaries dont work. To avioid confusion, I am deleting that comment.

@tpaviot when installing directly using wget, I noticed that 7.2.2 has compatible python version in its name (here), whereas 7.8.1 does not. So 7.8.1 is not corrupted, its just hard to find the right version for you python version.

As you suggested, only solution for running occ in container on mac is to build the occ from source.

But it should work if it work for you. Where could be the problem ? Bad path ? Bad compilation ?
