Thanks Gavin, I am using the latest SDK and the latest FFMPEG..
I tried this: ./configure --enable-static --disable-shared --enable-pic --sysroot="* /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk *" --extra-ldflags="-arch armv7 -isysroot * /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk * -miphoneos-version-min=*5.1*" --enable-cross-compile --arch=arm --target-os=darwin --cc="* /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc *" --cpu=cortex-a8 --extra-cflags="-arch armv7 -mfpu=neon -miphoneos-version-min=*5.1*" --disable-debug --enable-small *--disable-asm* based on your command, with some modifications in BOLD.... well.. it compiles... but when I try to link with my application I have: Undefined symbols for architecture armv7: "__Z13avcodec_open2P14AVCodecContextP7AVCodecPP12AVDictionary", referenced from: __Z4doItv in Smooth.o "__Z21avformat_write_headerP15AVFormatContextPP12AVDictionary", referenced from: __Z4doItv in Smooth.o "__Z26av_interleaved_write_frameP15AVFormatContextP8AVPacket", referenced from: __Z4doItv in Smooth.o "__Z7av_freePv", referenced from: __Z4doItv in Smooth.o "__Z10avio_flushP11AVIOContext", referenced from: __Z4doItv in Smooth.o "__Z15av_guess_formatPKcS0_S0_", referenced from: __Z4doItv in Smooth.o "__Z13av_dup_packetP8AVPacket", referenced from: __Z4doItv in Smooth.o "__Z15av_register_allv", referenced from: __Z4doItv in Smooth.o "__Z14av_dump_formatP15AVFormatContextiPKci", referenced from: __Z4doItv in Smooth.o "__Z14av_free_packetP8AVPacket", referenced from: __Z4doItv in Smooth.o "__Z20avcodec_find_decoder7CodecID", referenced from: __Z4doItv in Smooth.o "__Z10avio_closeP11AVIOContext", referenced from: __Z4doItv in Smooth.o "__Z19avformat_open_inputPP15AVFormatContextPKcP13AVInputFormatPP12AVDictionary", referenced from: __Z4doItv in Smooth.o "__Z16av_write_trailerP15AVFormatContext", referenced from: __Z4doItv in Smooth.o "__Z9avio_openPP11AVIOContextPKci", referenced from: __Z4doItv in Smooth.o "__Z13avcodec_closeP14AVCodecContext", referenced from: __Z4doItv in Smooth.o "__Z19avformat_new_streamP15AVFormatContextP7AVCodec", referenced from: __ZL17add_output_streamP15AVFormatContextP8AVStream in Smooth.o "__Z25avformat_find_stream_infoP15AVFormatContextPP12AVDictionary", referenced from: __Z4doItv in Smooth.o "__Z8av_freepPv", referenced from: __Z4doItv in Smooth.o "__Z22avformat_alloc_contextv", referenced from: __Z4doItv in Smooth.o "__Z13av_read_frameP15AVFormatContextP8AVPacket", referenced from: __Z4doItv in Smooth.o ld: symbol(s) not found for architecture armv7 clang: error: linker command failed with exit code 1 (use -v to see invocation) Any suggestion?
