Trying to compile x264 and ffmpeg for iPhone - "missing required architecture arm in file"
11 février 2013, par jtrimI'm trying to compile x264 for use in an iPhone application. I see there are instructions on how to compile ffmpeg for use on the platform here : http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2009-October/076618.html , but I can't seem to find anything this complete for compiling x264 on the iPhone. I've found this source tree : http://gitorious.org/x264-arm that seems to have support for the ARM platform.
Here is my config line :
./configure —cross-prefix=/usr/bin/ —host=arm-apple-darwin10 —extra-cflags="-B /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.2.sdk/usr/lib/ -I /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.2.sdk/usr/lib/"
...and inside
configure
I'm using the gas-preprocessor script (first link above) as my assembler :gas-preprocessor.pl gcc
When I start compiling, it chunks away for a little while, then it spits out these warnings and a huge list of undefined symbols :
ld : warning : option -s is obsolete and being ignored ld : warning : -force_cpusubtype_ALL will become unsupported for ARM architectures ld : warning : in /usr/lib/crt1.o, missing required architecture arm in file ld : warning : in /usr/X11R6/lib/libX11.dylib, missing required architecture arm in file ld : warning : in /usr/lib/libm.dylib, missing required architecture arm in file ld : warning : in /usr/lib/libpthread.dylib, missing required architecture arm in file ld : warning : in /usr/lib/libgcc_s.1.dylib, missing required architecture arm in file ld : warning : in /usr/lib/libSystem.dylib, missing required architecture arm in file Undefined symbols :
My guess would be that the problem has to do with the "missing required architecture arm in file" warning...any ideas ?
