[Unbound-users] various issues with python and unbound?

[Paul Wouters]

Hi,

While upgrading various branches with the latest unbound, I run
in issues with libunbound_wrap.c and swig.

On rawhide ("fedora 18") the shipped swig just segfaults:

On fedora 17 things seem to build fine.

On RHEL5 and RHEL6, I am seeing:

pythonmod/pythonmod.c:43: warning: ignoring #pragma GCC diagnostic
pythonmod/pythonmod.c:44: warning: ignoring #pragma GCC diagnostic

make: *** [libunbound_wrap.lo] Error 1

So there are some things that seem very sensitive to the tool chains used.
