I have a broken version of the script to build FLAC library.

Need help!

@ngocdaothanh

Thanks! I could build ffmpeg 2.1.1 with your script.

This script is working for all ffmpeg versions since 1.0.

@wumingyun

is there any possibility that ffmpeg before 1.0 can be compiled by xcode5?
Have you ever try that?
thanks!!!

@chris-magic

Thanks! But when I compile ffmpeg2.1.1 use your script ,I still encounter the problem "Unable to identify target architecture at /usr/bin/gas-preprocessor.pl line 82" .
I used iPhoneOS7.0.sdk .
I don't where is wrong .Thanks again.

@d370urn3ur

i had to change line 56: tar zxf ffmpeg-${VERSION}.tar.bz2 -C $SRCDIR to
tar jxf ffmpeg-${VERSION}.tar.bz2 -C $SRCDIR

the z option is for gzip archives and the script downloads bzip2 archive. tar failed every time unless I changed the "z" to "j". now it works fine

On my building environment XCode5/ios7, the "--cross-prefix="${DEVELOPER}/Toolchains/XcodeDefault.xctoolchain/usr/bin/" MUST be added to the configure script, if not the ranlib should be failed when compile armv7/armv7s.

@wumingyun No i didn't. I built only >1.0.
@d370urn3ur Thanks, i will fix it.

Thnx for the script! It saved me a lot of time. Can you also make it compile for x86_64? I want to use ffmpeg on Mac app and i've tried changing the arch to x86_64 but for some reason the library is not working as intended...

@renlifeng

wonderful! I just need to use ffmpeg

@Ankish

Update for xcode 6.1 with ios 8 ver above. Recommended changes to the script ?
Moreover in the path I${DEVELOPER}/Platforms/${PLATFORM}.platform/Developer/SDKs/${PLATFORM}${SDKVERSION}.sdk/usr/lib - only 5.0sdk is avaialble even though i user xcode 6.1 with ios 8.0. Is sdks path changed , any changes in script? Thanks!
