Installation on M1 still failing on newer version

[joeylitalien]

Hi Francis,

Thanks for your great work, love your library! I usually develop on Linux but wanted to try your lib on my M1 Macbook. To my surprise, it failed even on the latest release and a fresh virtual env. This is the error I am getting on a normal import:

Traceback (most recent call last):
  File "/tmp/test.py", line 2, in <module>
    import point_cloud_utils as pcu
  File "/tmp/demo/lib/python3.10/site-packages/point_cloud_utils/__init__.py", line 4, in <module>
    from ._pcu_internal import sample_mesh_poisson_disk, sample_mesh_random, \
ImportError: dlopen(/tmp/demo/lib/python3.10/site-packages/point_cloud_utils/_pcu_internal.cpython-310-darwin.so, 0x0002): tried: '/tmp/demo/lib/python3.10/site-packages/point_cloud_utils/_pcu_internal.cpython-310-darwin.so' (mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64e')), '/usr/lib/_pcu_internal.cpython-310-darwin.so' (no such file)

For the record, a manual build of v0.29.2 works just fine, just not through pip. I've tried running pip install point-cloud-utils==0.29.2 but I get the same result.

Best, Joey

Hey Joey, thanks for pointing this out! The issue seems to be with the CI building m1 packages on Intel macs. It passes a flag to indicate it’s supposed to build for M1 which I’m currently ignoring. So the m1 packages on PyPI are actually Intel Mac packages 😬😬😬.

For now building from source should work. I’ll need to fix the ci at some point. Sorry!

Hi, fwilliams, could u fix this error? I have the same issue to install it on my mac with M1 -:) thanks

@usccolumbia, fixing bugs for an open source library like this one requires having access to an M1/M2 machine, which is not always possible. Please be considerate and build the library from scratch as a temporary fix until @fwilliams finds the time to solve this problem.

Hello, I have tried to build from source but was unable to. I get this error. I saw this was mentioned in #42 but I couldn't see any fixes for it. Is there no fix for this? Thanks for any info.

@fwilliams it looks like GHA now have an apple silicon runner. If you specify macos-13 you get intel, and if you specify macos-14 you get apple silicon. I assume this will help with fixing deployment of builds:
