libopcodes.a isn't built with -fPIC, which prevents people from linking it into a shared library (on x86_64, at least).
Here's a patch against the F15 branch which recompiles libopcodes.a with -fPIC, based off of what was done with libbfd.a and libiberty.a.
Ping, any update on this?
Ping, does the patch look reasonable?
Sorry for the very long delay in responding to this issue. Your patch look reasonable and so I have applied it to the rawhide, F16 and F15 releases.
