Describe the issue:

When trying to build numpy, I get the following error during evaluating BLAS variants:

../../numpy/meson.build:119:13: ERROR: Unhandled python exception

    This is a Meson bug and should be reported!

ERROR Backend subprocess exited when trying to invoke build_wheel

The issue appears specific to pep517 backend: on the same system, it does not happen if pep517 is disabled.

@rgommers Confirmed the same failure on 10.6.8 x86_64 (so error is unrelated to PowerPC or Rosetta).

Reproduce the code example:

This is a build (or rather configure) error. What seems to fail is this chunk:

# First try scipy-openblas, and if found don't look for cblas or lapack, we
# know what's inside the scipy-openblas wheels already.
if blas_name == 'openblas' or blas_name == 'auto'
  blas = dependency('scipy-openblas', required: false)
  if blas.found()
    blas_name = 'scipy-openblas'
  endif
endif
if blas_name == 'auto'
  foreach _name : get_option('blas-order')
    if _name == 'mkl'
      blas = dependency('mkl',
        modules: ['cblas'] + blas_interface + mkl_opts,
        required: false,  # may be required, but we need to emit a custom error message
        version: mkl_version_req,
      )
      # Insert a second try with MKL, because we may be rejecting older versions
      # or missing it because no pkg-config installed. If so, we need to retry
      # with MKL SDL, and drop the version constraint (this always worked).
      if not blas.found() and mkl_may_use_sdl
        blas = dependency('mkl', modules: ['cblas', 'sdl: true'], required: false)
      endif
    else
      if _name == 'flexiblas' and use_ilp64
        _name = 'flexiblas64'
      endif
      blas = dependency(_name, modules: ['cblas'] + blas_interface, required: false)
    endif
    if blas.found()
      break
    endif
  endforeach
else
  if blas_name == 'mkl'
    blas = dependency('mkl',
      modules: ['cblas'] + blas_interface + mkl_opts,
      required: false,
      version: mkl_version_req,
    )
    # Same deal as above - try again for MKL
    if not blas.found() and mkl_may_use_sdl
      blas = dependency('mkl', modules: ['cblas', 'sdl: true'], required: false)
    endif
  else
    blas = dependency(blas_name, modules: ['cblas'] + blas_interface, required: false)
  endif
endif

../../numpy/meson.build:119:13: ERROR: Unhandled python exception

    This is a Meson bug and should be reported!

ERROR Backend subprocess exited when trying to invoke build_wheel

Python and NumPy Versions:

numpy 1.26.1
python 3.11.4

Runtime Environment:

macOS 10.6.8 x86_64
macOS 10.6.8 ppc (Rosetta)

Context for the issue:

numpy is broken in Macports for a number of systems after it switched to pep517 backend. Given that Python 3.12+ needs that, reverting is not an option.

    The same error on 10.7 x86_64 on buildbot: https://build.macports.org/builders/ports-10.7_x86_64-builder/builds/168185/steps/install-port/logs/stdio

    Update: as @dnicolodi suggested earlier, the cause for the error is in fact xcrun. Specifically, this code in mesonbuild/dependencies/blas_lapack.py breaks the build:

        def check_macOS_recent_enough(self) -> bool:
        # We need the SDK to be >=13.3 (meaning at least XCode 14.3)
        cmd = ['xcrun', '-sdk', 'macosx', '--show-sdk-version']
        sdk_version = subprocess.run(cmd, capture_output=True, check=True, text=True).stdout.strip()
        macos_version = platform.mac_ver()[0]
        deploy_target = os.environ.get('MACOSX_DEPLOYMENT_TARGET', macos_version)
        return sdk_version >= '13.3' and deploy_target >= '13.3'

    There are two problems here:

    1. The syntax used is unsupported on macOS < 10.8.
    svacchanda$ xcrun -sdk macosx --show-sdk-version
xcrun: error: unrecognized option: --show-sdk-version

usage: 
xcrun [-verbose] [-no-cache] [-kill-cache] [-sdk <sdkroot>] [-log] [-run] <utility> [utility argument(s) ...]
xcrun [-verbose] [-no-cache] [-kill-cache] [-sdk <sdkroot>] -find <utility> 
<tool> [tool arguments ...]
    1. Restriction to the OS version is totally unjustified: I can say for the fact that numpy 1.26.2 builds fine at least on 10.6 (and I am reasonably sure it will build on 10.5 too).

    The code checking for the SDK version need to be read in context: https://github.com/numpy/meson/blob/708d52853d744916884d66a630f20b68cf4d3674/mesonbuild/dependencies/blas_lapack.py#L723-L729 The check is there to ensure that the Accelerate framework is used only on macOS 13.3. Most likely, the fix is to catch the subprocess error and assume the SDK version is too old in this case.

    By the way, the version comparisons here https://github.com/numpy/meson/blob/708d52853d744916884d66a630f20b68cf4d3674/mesonbuild/dependencies/blas_lapack.py#L744C1-L750C65 seem broken to me. What is done is a lexicographic comparison not a version comparison. In other words, if sdk_version = '13.10' the sdk_version >= '13.3' check would fail. Same for deploy_target.

    The code checking for the SDK version need to be read in context: https://github.com/numpy/meson/blob/708d52853d744916884d66a630f20b68cf4d3674/mesonbuild/dependencies/blas_lapack.py#L723-L729 The check is there to ensure that the Accelerate framework is used only on macOS 13.3. Most likely, the fix is to catch the subprocess error and assume the SDK version is too old in this case.

    @dnicolodi Thank you. That sounds like a good way to solve the problem, then we do not need to bother with finding a way to get SDK version from Python on < 10.8.

    @barracuda156 Please note that the version of macOS you are trying to build for is unsupported at least since November 19, 2015 (end of support for macOS 10.8). There is no realistic way for anyone to test new development on that OS. The amount of things that do not work on that an old system increases exponentially as time passes. If you have hardware that is supported only by such old releases of macOS, installing a different but current OS on it would IMO be time better spent than keep fixing build failures.

    @dnicolodi There is no failures with the build itself, what fails is configure stage, and this is a totally avoidable error.
    Of course I do not expect the upstream to keep testing everything on every existing macOS version, it is clearly both unrealistic and wasteful.
    Normally older OS testing is community-based. And not everything may be fixable, or fixable with reasonable efforts; here, however, we just have a script with a missing condition. Since the script is designed to filter out older OS, as you point out above, it should filter out <10.7 too, so that Accelerate is not used, but another BLAS is picked. There is no need to prohibit building on <10.7, since as a matter of fact it works.

    Thanks for digging in @barracuda156 and @dnicolodi. I agree with the conversation above - macOS versions that old are unsupported, but in this case the fix is simple enough that we'll fix it. There's no guarantee of there not being more issues on macOS PPC of course. I'm surprised more every year that someone is still using that.

    @rgommers Thank you very much, greatly appreciated!

    (P. S. As long as GCC upstream supports macOS PPC, it remains usable with much of the modern software running, at least on the late G5 hardware. The Quad with maxed RAM is decently fast in fact.)

    The fix in gh-25455 should take care of the issues reported here. The plan is to also backport that fix to 1.26.3
