I am in the process of getting libpfm into fedora rawhide. When building with
the older version of swig in rawhide (2.0.6) there was the following message in
the build:
swig -python -I../include -o src/perfmon_int_wrap.c src/perfmon_int.i
src/perfmon_int.i:95: Warning 521: Illegal destructor name ~perf_event_attr_t.
Ignored.
For the newer version of swig in rawhide (2.0.7) swig gets a segmentation
fault. I have filed the following bug to get swig fixed:
https://bugzilla.redhat.com/show_bug.cgi?id=830249
In the meantime it would be good to get libpfm upstream fixed so swig doesn't
complain about this error. I think that the attached patch eliminates this
problem. This is based on the approach mentioned in a similar swig bug report:
