I'm still trying to figure out why some of the macros are throwing the
error with RPM. I notice that the file
/etc/rpm/macros.python3.rh-python36 has several lines like the
following:
%%{scl_no_vendor}_python_requires /usr/lib/rpm/pythondeps-scl-36.sh
--requires %{?scl:rh-python36-}
If I comment out all of those lines, the "Macro % has illegal name..."
errors go away. If I uncomment one line, I get one instance of the
error.
Looking in some of the other macro files, I did not see any instance
of %%{macro_name}, it was always %{macro_name} ... so I removed one of
the % at the beginning of the line, and I still get the illegal name
error.
Does anyone know where I should look next, lest I compile RPM from
source and run it in a debugger?
