Building FFMpeg Error in IOS6.1 unable to create an executable file

Question

I am trying to build ffmpeg on iOS6.1 (armv7), when I try to run ./configure like this:

./configure --disable-doc --disable-ffmpeg --disable-ffplay
--disable-ffserver    --enable-cross-compile --arch=arm --target-os=darwin    --cc=/applications/xcode.app/contents/Developer/usr/bin/gcc    --as='gas-preprocessor/gas-preprocessor.pl /applications/xcode.app/contents/Developer/usr/bin/gcc'   
--sysroot=/applications/xcode.app/contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk
--cpu=cortex-a8 --extra-cflags='-arch armv7'    --extra-ldflags='-arch armv7 -isysroot /applications/xcode.app/contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk'
--enable-pic

I get the following error:

/applications/xcode.app/contents/Developer/usr/bin/gcc is unable to create an executable file. C compiler test failed.

Could somebody please provide the correct parameters in iOS6.1?

Update Command :

./configure --disable-doc --disable-ffmpeg --disable-ffplay --disable-ffserver --enable-cross-compile --arch=arm --target-os=darwin --cc=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/llvm-gcc-4.2/bin/arm-apple-darwin10-llvm-gcc-4.2 --as='gas-preprocessor/gas-preprocessor.pl /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/llvm-gcc-4.2/bin/arm-apple-darwin10-llvm-gcc-4.2' --sysroot=/applications/xcode.app/contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk --cpu=cortex-a8 --extra-cflags='-arch armv7' --extra-ldflags='-arch armv7 -isysroot /applications/xcode.app/contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk' --enable-pic

Error in Update Command :

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/llvm-gcc-4.2/bin/arm-apple-darwin10-llvm-gcc-4.2 is unable to create an executable file. C compiler test failed.

If you think configure made a mistake, make sure you are using the latest version from Git. If the latest version fails, report the problem to the [email protected] mailing list or IRC #ffmpeg on irc.freenode.net. Include the log file "config.log" produced by configure as this will help solving the problem.

earlier your sysroot and isysroot were pointing to iPhoneOS5.1. Now that you've changed them to iPhoneOS6.1 (which is the correct path) try again using --cc=/applications/xcode.app/contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc instead of the arm-apple-darwin10... — Tushar Koul

You are using...

--cc=/applications/xcode.app/contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc

That's wrong for armv7, you should be doing...

--cc=/applications/xcode.app/contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/arm-apple-darwin10-gcc-4.2.1

Change the above to whatever arm-apple-darwin10-gcc-x.x.x version you have that bin folder.

As well, change the gas-preprocessor's target compiler to the same.

--as='gas-preprocessor/gas-preprocessor.pl /applications/xcode.app/contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/arm-apple-darwin10-gcc-4.2.1'

Additionally, don't put an -arch armv7 in your --extra-cflags, you don't need it and you may get an error: unrecognized command line option "-arch"
