[Libav-user] Unable to compile i386 compatible ffmpeg dylibs on Mac OS X

[Simon Daniels]

Hi Carl,

Here's what I get with ./configure --disable-static --enable-shared
--disable-outdev=sdl --disable-bzlib --disable-libfreetype
--disable-libopenjpeg --enable-zlib --enable-runtime-cpudetect
--extra-cflags="-m32 -fomit-frame-pointer" --extra-ldflags="-m32
-fomit-frame-pointer" --cc="gcc -m32 -fomit-frame-pointer"

libavcodec/h264.c: In function ‘fill_filter_caches’:
libavcodec/h264.c:3224: warning: initialization from incompatible pointer type
libavcodec/h264.c:3301: warning: initialization from incompatible pointer type
libavcodec/h264.c:3316: warning: initialization from incompatible pointer type
CC	libavcodec/h264_cabac.o
cc1: error in backend: Ran out of registers during register allocation!
make: *** [libavcodec/h264_cabac.o] Error 1


Here is the uncut make V=1:

gcc -m32 -fomit-frame-pointer -I.
-I"/Users/user/Downloads/ffmpeg-0.8.7" -D_ISOC99_SOURCE
-D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -DPIC -DHAVE_AV_CONFIG_H

libavcodec/h264_cabac.c
cc1: error in backend: Ran out of registers during register allocation!
make: *** [libavcodec/h264_cabac.o] Error 1


When I ran only ./configure --cc="gcc -m32", I got this from make V=1

gcc -m32 -I. -I"/Users/user/Downloads/ffmpeg-0.8.7" -D_ISOC99_SOURCE
-D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -DHAVE_AV_CONFIG_H -std=c99

Thanks!
