Re: [Linphone-developers] compile [libmediastreamer.so.0] problem

[Simon Morlat]

Hello,

Before everything, you should read a tutorial about automake/autoconf.
You'll learn that you should never edit a Makefile, but a Makefile.am, and 
you'll learn how to add files into library and add custom flags.
