Hi,

Following the wiki: http://wiki.freeswitch.org/wiki/Event_Socket_Library
On MacOSX 10.5, I can't get ESL for ruby work. make throws error:

sevens-mac-pro:~/workspace/test/freeswitch/trunk/libs/esl$ make rubymod

Thanks for any help.

The makefile will have to be changed to work with OS X since the linking is done differently.

It would be very similar to this one http://www.bkw.org/esl.imac.diff


Below will get it to compile:

Thanks Brain. Got ESL.so, however on my Mac it is #include <ruby.h> instead of <ruby/ruby.h>.


But it can't find the ESL when I require 'ESL' in ruby. Even I put ESL.so in one of the dir of $:


Any clue for me?
