    python-config has the following non-trivial code for discovery of cflags/ldflags, which should be callable as a sysconfig API instead:

    elif opt in ('--includes', '--cflags'):
    flags = ['-I' + sysconfig.get_path('include'),
             '-I' + sysconfig.get_path('platinclude')]
    if opt == '--cflags':
        flags.extend(getvar('CFLAGS').split())
    print(' '.join(flags))

elif opt in ('--libs', '--ldflags'):
    libs = getvar('LIBS').split() + getvar('SYSLIBS').split()
    libs.append('-lpython' + pyver + sys.abiflags)
    # add the prefix/lib/pythonX.Y/config dir, but only if there is no
    # shared library in prefix/lib/.
    if opt == '--ldflags':
        if not getvar('Py_ENABLE_SHARED'):
            libs.insert(0, '-L' + getvar('LIBPL'))
        libs.extend(getvar('LINKFORSHARED').split())
    print(' '.join(libs))

    Also, it begs the question why distutils doesn't use the same code in its compiler class, or even in customize_compiler()...

    +1 on the request. I don’t think it can go in 3.2, though. I’ll propose a patch, this will let me learn more about the flags.

    Also, it begs the question why distutils doesn't use the same code in
    its compiler class, or even in customize_compiler()...

    Certainly because distutils pre-dates python-config. In packaging, we should certainly use sysconfig functions.

    @eric.araujo curious if you still have the interest to work on this. If not, I can help open a PR.

    I don’t have specific expertise in this, so please take it!

    I can help out, but would like to wait until we get a resolution in python/issues-test-cpython#25718 as it will likely conflict.

    Closing as duplicate of more recent issue, which has more up to date discussion.
