[FFmpeg-user] Error in audiotoolboxenc.o when compiling on OS X 10.6.8

[Jonathan Alland]

Hello!

I am trying to compile a build of ffmpeg on macOS X 10.6.8. My hope is to eventually get a statically linked binary which is also Snow Leopard compatible.

I am using the following options:

./configure --cc=/usr/bin/clang --prefix=/opt/ffmpeg --extra-version=tessus --enable-avisynth --enable-fontconfig --enable-gpl --enable-libass --enable-libbluray --enable-libfreetype --enable-libgsm --enable-libmodplug --enable-libmp3lame --enable-libopenjpeg --enable-libopus --enable-librubberband --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libtheora --enable-libtwolame --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxvid --enable-libzmq --enable-version3 --pkg-config-flags=--static --enable-nonfree --enable-libfdk-aac --extra-ldflags=-L/opt/local/lib

The compilation fails at libavcodec/audiotoolboxenc.o. The last few lines are:

Please let me know if there's anything I can try. If Snow Leopard is just too old to work, please let me know that too! Thank you!
