• Issue #1 when compiling Xuggler for Raspberry pi with libspeex

  23 juillet 2014, par Ashish Sharma

  I am trying to compile Xuggler for Raspberry Pi(Running on Debian OS aka Raspbian),

  I followed the ’Basic Build Instructions’ available here for compiling Xuggler.

  After I successfully installed all the prerequisites and set the correct paths, I ran the following command :

  ant run-tests

  After sometime I am facing the following error and the ant build fails :
