    As part, I assume, of PR19503, that includes 91 changed files with 27,058 additions and 147 deletions the AIX buildbot is broken.

    Rather than looking/finding Modules/ld_so_aix (where I expect it to be) tests are failing, ulitmately because they look/expect it to be in a new location, and with a name dependent on being debug (or not) as the bots are configured using --pydebug.

    Examples:
    FileNotFoundError: [Errno 2] No such file or directory: '/home/shager/cpython-buildarea/3.x.edelsohn-aix-ppc64/build/target/lib/python3.9/config-3.9d/ld_so_aix'

    or

    FileNotFoundError: [Errno 2] No such file or directory: '/home/aixtools/buildarea/3.x.aixtools-aix-power6/build/target/lib/python3.9/config-3.9d/ld_so_aix'

    This is (only?) in test_peg_generator.

    One traceback example:

    It looks like the newly added test_peg_gemerator tries to build C code at run time as part of executing the test. So most likely the test is not invoking distutils with the same set of options and/or environment variable values that the main Python setup.py does when building standard library C extension modules at Python build time. Pablo?

    Ned, the analysis seems correct. We need to fix test_peg_generator so it uses the same build options as the interpreter. I am slightly surprised as I was under the assumption that distutils propagates the compiler options that were used when the interpreter was built automatically

    Michael, could you check if PR 19674 fixes the issue? That PR ensures that we are using the same set of flags as to when building the interpreter, which independently of this issue, is the correct thing to do.

    I suspect that given the path '/home/aixtools/buildarea/3.x.aixtools-aix-power6/build/target/lib/python3.9/config-3.9d/ld_so_aix', distutils is triying to use an installed 'ld_so_aix' instead of the one in Modules/ld_so_aix.

    This is with gcc as compiler. Shall repeat with xlc and only update if different.

    I think the problem here is that distutils in AIX needs the ld_so_aix file installed and is not able to use the one in Modules from the source directory. This happens because sysconfig has "config-3.9d/ld_so_aix", which does not exist until python is installed.

    I propose skipping test_peg_generator for now, so that we don't hold the alpha6 release. It actually only tests the generator and not the parser and since we don't plan on adding new operators in the very near future, we can skip it and fix it after the release.

    Interestingly, test_distutils has the same problem, but basically skips the test:

    test_build_ext (distutils.tests.test_build_ext.BuildExtTestCase) ... skipped "The '/usr/local/lib/python3.9/config-3.9d/ld_so_aix' command is not found"

    so that we don't hold the alpha6 release.

    AIX is not a STABLE buildbot so I cannot hold the release

    We need to do the same thing as test_build_ext does:

    Michael, can you check if AIX is happy with the current master? :)

    New changeset 9e6a131 by Pablo Galindo in branch 'master':
    bpo-40370: Use the same compile and link args as the interpreter used in test_peg_generator (GH-19674)

    Tested on an AIX system:

    [pablo@ibm_machine cpython (master)]$ uname -a
    AIX ibm_machine 1 7 ******* powerpc ******** AIX
    [pablo@ibm1 cpython (master)]$ ./python -m test test_peg_generator
    0:00:00 Run tests sequentially
    0:00:00 [1/1] test_peg_generator

    == Tests result: SUCCESS ==

    1 test OK.

    Total duration: 5.0 sec
    Tests result: SUCCESS

    I will mark this issue as fixed as It was failing before on this machine and now the test suceeds. Feel free to reopen if is not fixes in your system :)

    Thanks for the quick work. I’ll test with xlc as well, as the builds behave differently this afternoon.

    Thanks for the quick response. I see both bots are good.
