Same issue on M1 MacOS, Python 3.10. I ran poetry add ecos, and it fails with:

      ecos/ecos_bb/ecos_bb.c:388:5: error: implicitly declaring library function 'memcpy' with type 'void *(void *, const void *, unsigned long)' [-Werror,-Wimplicit-function-declaration]
          memcpy(problem->tmp_branching_bool_node_id, get_bool_node_id(node_idx, problem), bool_node_size);

      error: command '/usr/bin/clang' failed with exit code 1

Any ideas on how to fix that?

Installing 2.0.5 version worked for me in Mac M1 processor. Looks to be some issue with the latest version. pip install ecos==2.0.5

[jacopofar]

@thirumalairajr could you share on which Python version you are? I'm trying to help a colleague with M1 but cannot get this to work with Python 3.9 nor building it

[baslia]

Hey, I have the same issue with M1 mac and python 3.9

[thirumalairajr]

@thirumalairajr could you share on which Python version you are? I'm trying to help a colleague with M1 but cannot get this to work with Python 3.9 nor building it

I am using Python 3.11.2
