[tor-talk] Tor build failed - can't find libevent..
Hello everyone,
I go by the name of Air0s & this is my first post to the list so pls bear
with me..
I've got a problem building Tor from source which has to do with libevent..
Check-out the response I got from Nick Mathewson..

So here I am.. I've removed the 1.4 version of libevent but now
I need to set the --with-libevent-dir option or change the CFLAGS/LDFLAGS..
# pkg_version -v | grep libevent
>>> libevent2-2.0.16
# locate libevent
>>> /usr/local/lib => This is the location of the old 1.4
library
>>> /usr/local/lib/event2 => This is the new 2.0 library
Question is how & where do I set these flags..?
Much obliged for any feedback..
Regards,
E.
