Hi,
with latest wireshark-1.8.2, I noticed I get error messages on wireshark
or tshark startup:
/lib64/libwireshark.so.2: undefined symbol: py_create_dissector_handle
Digging a bit into compile process, I found out that
py_create_dissector_handle is not mentioned in libwireshark.def and even
if it was there, it would be removed during compilation. Attached patch
fixes the problem for me.
I tried to understand bug
https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=6448, but I failed
to see how SVN rev. 39439 *adds* the python symbols to libwireshark.sym,
it can only remove them. Do I miss something?
