[Ccrtp-devel] rtcpp-1.5.0/demo/rtpsend ... undefined reference to 'pthread_...'

[Chuck Harrison]

Working on the embbedded mips install for openWRT

Now libccrtp1.la has been created! Rah! Rah! On with the show...

The rtcpp-1.5.0/demo/Makefile does not put a -pthread flag in the
link, but the first demo file to be processed, rtpsend, fails --
looking for pthread references.

As a trial, I added -pthread to the Makefile.in
