qcc4cp / qcc Goto Github PK

Hello,

After following the instructions for compiling the C++ code in Docker, I get the following Bazel error:

`$ docker build -t qcc4cp:latest .
DEPRECATED: The legacy builder is deprecated and will be removed in a future release.

I get the exact same error when running the compilation outside of Docker following README.Linux.md. I am on Ubuntu 22.04.

I am not a Bazel user and Google so far didn't help.

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 am using Linux Ubuntu 22.04.3 LTS (WSL 2) on a windows 11 machine and I have python 3.10, numpy 1.26.3 and bazel 7.0.0 installed.
I modified the WORKSPACE script according to my path to python and numpy, which are respectively:
/usr/include/python3.10
/usr/local/lib/python3.10/dist-packages/numpy/core/

However, when I go in qcc/src/lib and try to build using bazel build all I got this error:

ERROR: /home/username/qcc/WORKSPACE:1:21: //external:third_party_python: invalid label '/home/username/qcc/python.BUILD' in attribute 'build_file' in 'new_local_repository' rule: invalid target name '/home/username/qcc/python.BUILD': target names may not start with '/'
ERROR: /home/username/qcc/WORKSPACE:8:21: //external:third_party_numpy: invalid label '/home/username/qcc/numpy.BUILD' in attribute 'build_file' in 'new_local_repository' rule: invalid target name '/home/username/qcc/numpy.BUILD': target names may not start with '/'
ERROR: Error computing the main repository mapping: Encountered error while reading extension file 'toolchains/jdk_build_file.bzl': no such package '@@rules_java_builtin//toolchains': error loading package 'external': Could not load //external package

SOLUTION

My solution was the following:

• in the main folder qcc, create a folder called external:
• move python.BUILD and numpy.BUILD from qcc to qcc/external
• then modify the WORKSPACE script as follows:

new_local_repository(
    name = "third_party_python",
    build_file = "//external:python.BUILD",
    path = "/usr/include/python3.10",
)

new_local_repository(
    name = "third_party_numpy",
    build_file = "//external:numpy.BUILD",
    path = "/usr/local/lib/python3.10/dist-packages/numpy/core/",
)

This solved the issue for me.
Hope this was helpful, have a greate day :)
