Re: [Ccrtp-devel] undefined reference

[Federico Montesino Pouzols]

        Hi,

        To compile the demos, just use make inside the demo
directory. You can compile them all with just make, or use 'make
rtphello'. ccRTP depends on Common C++, so to compile ccRTP based
applications you should use 'ccgnu2-config' in order to specify CC++
compiler flags and libraries. For example:

        g++ `ccgnu2-config --flags --libs` -lccrtp1 -ofoo foo.cpp

        The mailing list web is at
        mail.gnu.org/mailman/listinfo/ccrtp-devel
