[New-bugs-announce] [issue45221] Linker flags starting with -h breaks setup.py (regression)

[ux]

New submission from ux <bugs-python-ahmiupek at pkh.me>:

Hi,

Since 3.8 (included), the following build command fails:

    LDFLAGS=-headerpad_max_install_names ./configure
    make

With the following error:

    setup.py: error: argument -h/--help: ignored explicit argument 'eaderpad_max_install_names'


A quick hack in setup.py "fixes" the issue:

-                options, _ = parser.parse_known_args(env_val.split())
+                options, _ = parser.parse_known_args([x for x in env_val.split() if not x.startswith('-h')])

Another workaround as a user is to do use `LDFLAGS=-Wl,-headerpad_max_install_names`.
