--- Comment #12 from Emil Velikov emil.l.velikov@gmail.com --- Paul small tip from a fellow Arch user: The quickest/easiest way to get debug symbols is to add 'debug' in the OPTIONS array of the PKGBUILD and rebuild the package [1]. This way separate *debug* packages will be created.
The configure's --enable-debug does something a big different :-)
