In FFmpeg we check the endianness like this: check_cc <<EOF || die "endian test failed" unsigned int endian = 'B' << 24 | 'I' << 16 | 'G' << 8 | 'E'; EOF od -t x1 $TMPO | grep -q '42 *49 *47 *45' && enable bigendian This works on every combination of build and target system we use. -- Måns Rullgård m...@mansr.com
