Using 64-bit Ubuntu 12.04 LTS... ? Today I noticed ffmpeg libavcodec, libavformat, ... libavxxx were in the Ubuntu update list. Fetched and installed these and successfully rebuilt pjsip 2.0.1, i.e. this time there were no compilation errors and application and samples were present. Build problem solved. -------------- next part -------------- An HTML attachment was scrubbed...
