ruby extconf.rb install fxruby
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.
This is what I get when I'm trying to install fxruby, I did some reasearch and maybe I'm missing some dependencies.
So, how do i know where mkmf.log is located so I can see this?
