Description Jeremy Messenger freebsd_committer 2011-03-06 16:50:00 UTC
When you have libevent and libevent2 installed then try to build
transmission* and other ports that depend on libevent2. Those ports will
get build failure because of incorrect in the libevent*.pc when build
ran like this:

# pkg-config --libs libevent
-L/usr/local/lib/event2 -levent
# pkg-config --libs libevent_openssl
-L/usr/local/lib/event2 -levent_openssl -levent
# pkg-config --libs libevent_pthreads
-L/usr/local/lib/event2 -levent_pthreads -levent

It will pick up libevent-1.4 library instead of libevent-2.0.


The fix is to patch in those libevent*.pc by add '-2.0' in the front of those

# ldconfig -r | grep libevent
	606:-levent-2.0.5 => /usr/local/lib/event2/libevent-2.0.so.5
	607:-levent_core-2.0.5 => /usr/local/lib/event2/libevent_core-2.0.so.5
	608:-levent_extra-2.0.5 => /usr/local/lib/event2/libevent_extra-2.0.so.5
	609:-levent_pthreads-2.0.5 => /usr/local/lib/event2/libevent_pthreads-2.0.so.5

# pkg-config --libs libevent
-L/usr/local/lib/event2 -levent-2.0
# pkg-config --libs libevent_openssl
-L/usr/local/lib/event2 -levent_openssl-2.0 -levent-2.0
 pkg-config --libs libevent_pthreads
-L/usr/local/lib/event2 -levent_pthreads-2.0 -levent-2.0

With that, those ports are able to build while have devel/libevent and
devel/libevent2 installed in the system with no problem. Oh yeah, here's
