  • Issue #2 when compiling Xuggler for Raspberry pi with libx264

    2 août 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 at libx264 :
