ios - Integrating ffmpeg in xcode5, Cannot find gcc -

i have been trying integrate ffmpeg in xcode5. step [here][1]

[1]: ffmpeg integration on iphone/ ipad project says cc parameter needs gcc in iphoneos.platform.

but not find in xcode5. nowadays in xcode 4.6.3 have.

i tried ./configure command cc gcc xcode4. :

./configure --prefix=armv7 --disable-ffmpeg --disable-ffplay --disable-ffprobe --disable- ffserver --enable-avresample --enable-cross-compile -- sysroot="/applications/xcode5.app/contents/developer/platforms/iphoneos.platform/developer/sdks/iphoneos7.0.sdk" --target-os=darwin --cc="/applications/xcode4.6.3.app/contents/developer/platforms/iphoneos.platform/developer/usr/bin/gcc" --extra-cflags="-arch armv7 -mfpu=neon -miphoneos-version-min=6.0" --extra-ldflags="-arch armv7 -isysroot /applications/xcode5.app/contents/developer/platforms/iphoneos.platform/developer/sdks/iphoneos7.0.sdk -miphoneos-version-min=6.0" --arch=arm --cpu=cortex-a9 --enable-pic

it works ok create command after fails this:

libavcodec/arm/mdct_vfp.s:113:unknown register alias 'tcos_d0_head' libavcodec/arm/mdct_vfp.s:114:unknown register alias 'tcos_d1_head' libavcodec/arm/mdct_vfp.s:115:unknown register alias 'tcos_s0_tail' make: *** [libavcodec/arm/mdct_vfp.o] error 1
