Hello all! I'm having trouble with a cross compiled libopus for an embedded application and would like some help. preamble: embedded details: processor: bf537 kernel: Linux release 3.0.8-ADI-2011R1-svn4693, build #2834 Fri Apr 22 12:35:34 ADT 2016 toolchain: bfin-linux-uclibc-gcc release gcc version 4.3.5 (ADI-2011R1-RC4) audio interface: ALSA opus: version: 1.1.2 build process: export CC=...
