- dnl Some versions of SWIG (like 3.0.12) generate code that produces
- dnl -Wcast-function-type warnings. This warning is present in gcc >= 8. This
- dnl combo happens on RHEL/Centos 8, for example. Later versions of SWIG (like
- dnl 4.0.1) have the correct function signatures to not produce this warning.
- dnl It's simpler to just disable the warning globally.
- dnl
- dnl Note that the Debian/Ubuntu SWIG package 3.0.12-2 contains a local patch to
- dnl fix this (python-fix-function-cast-warnings.patch), so you won't be able to
- dnl reproduce the warning using that package.
