xcrun -sdk iphoneos clang is unable to create an executable file.

[daneov]

Dear,

When executing the script I receive the following output :

sh build-ffmpeg.sh 
    building arm64...
    Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
    Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
    xcrun -sdk iphoneos clang is unable to create an executable file.
    C compiler test failed.

The script is a fresh checkout, I'm trying ffmpeg version 2.7.2 & I've set the deployment target in the script to 7.0.

I've never done something like this before, so if you require additional logs/information I'll be happy too, if you point me to where I should get them from as well :)

Thanks in advance.

I have the same problem I'm using the script with Xcode 6.4 and with yam 1.3.0

if I double click on the config log I get this warning

You must be using Xcode 6. "-fembed-bitcode" is only available in Xcode 7. Edit build-ffmpeg.sh and remove "-fembed-bitcode".
