Compiling lilxgates in MacBook Air M2

[maremnev]

Hi!

I tried to run qcc simulator on a MacBook Air with the processor M2. The macOS is Ventura 13.5.2. It works correctly. The python was installed though brew and downloaded by git.

But I can't run it with C++ accelerator, the module returns the message:

**************************************************************`
  WARNING: Could not find 'libxgates.so'.
  Please build it and point PYTHONPATH to it.
  Execution is being re-directed to a Python implementation,
  performance may suffer greatly.
  **************************************************************`

All paths are corrected according libraries place that file WORKSPACE takes into accounts the python positions:

new_local_repository(
    name = "third_party_python",
    build_file = __workspace_dir__ + "/python.BUILD",
    # Configure:
    path = "/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.9/Headers/",
)

new_local_repository(
    name = "third_party_numpy",
    build_file = __workspace_dir__ + "/numpy.BUILD",
    # Configure:
    path = "/Users/maremnev/Library/Python/3.9/lib/python/site-packages/numpy/core/",
)

And variables PATH and PYTHONPATH are corrected too:

export PATH=/Users/maremnev/WorkPlace/qcc:$PATH
export PYTHONPATH=/Users/maremnev/WorkPlace/qcc:$PYTHONPATH

export PYTHONPATH=/Users/maremnev/WorkPlace/qcc/bazel-bin/src/lib:$PYTHONPATH

Command bazel build all returns no errors. But it made in directory qcc/bazel-bin/src/lib files libxgates.a and libxgates.dylib, but python searchs for file libxgates.so.

I guess it's a remainder from Linux.

How to compile the library correctly in Mac? May be it's needed to point the another library in python?

I eliminated the warning message by copying libxgates.dylib into libxgates.so. But I'm not sure it's correct.

Thanks Mikhail

Yes, this seems to work, I ran into the same issue with a new MacMini I just got. I actually don't know what exactly is happening here ;-) I will investigate and likely update something to make it work across environments. I'll keep you posted.

Hmm, I tried but failed. I think I will have to update the documentation for MacOS and also improve the warning message a bit. Thanks R

Oh wait, as I write this notice, it turns out the solution may be to just rename the rule in the src/lib/BUILD file to specify the full filename (libxgates.so instead of just xgates). I will check that in and test it for the OSs that I have.

Thanks R

The fix seems to work. Checked in. Thank you again (I also added your name to the Thank You notes in the README.md).
