Hi I trying to follow the source compile instructions at https://trac.ffmpeg.org/wiki/CompilationGuide/Centos for CentOS 7.1

however on make stage i always git the error - the full log is at https://gist.github.com/centminmod/ba9cbd30b4cd79bb4ef6

okay seems problem was with my use of ccache, if i bypass it it works fine with

cmake -DCMAKE_C_COMPILER=gcc -DCMAKE_CXX_COMPILER=g++ -G "Unix Makefiles" -DCMAKE_INSTALL_PREFIX="${OPT}/ffmpeg" -DENABLE_SHARED:bool=off ../../source
make
make install
