Open knutster opened this issue 1 year ago • 3 comments

Describe the bug The arm64 (aarch64) server architecture is becoming more commonplace yet python-mip doesn't not work on these architectures.

To Reproduce Try to run a model on aarch64.

Expected behavior The model is parsed and run.

Error received

An error occurred while loading the CBC library:	 
cannot load library '/usr/local/lib/python3.10/site-packages/mip/libraries/cbc-c-linux-x86-64.so': /usr/local/lib/python3.10/site-packages/mip/libraries/cbc-c-linux-x86-64.so: cannot open shared object file: No such file or directory.  
Additionally, ctypes.util.find_library() did not manage to locate a library called '/usr/local/lib/python3.10/site-packages/mip/libraries/cbc-c-linux-x86-64.so'

Desktop (please complete the following information):

  • Operating System, version: docker container python-3.10-slim (bookworm and bullseye) aarch64
  • Python version: 3.10.x
  • Python-MIP version (we recommend you to test with the latest version): 1.16rc0 and earlier

Add pull request #391 to solve the above.

Yes for MacOS, not Linux. Not quite the same thing.
