# # Description
1. gas-preprocessor.pl this file before, but tested, in the XCODE4 environment is needed, XCODE5 environment is no longer necessary.
2./applications/xcode.app/contents/developer/toolchains/xcodedefault.xctoolchain/usr/bin/cc here cc C + + clang++ It's all clang soft connections.
3. One more-miphoneos-version-min=7.0, no this field will make a dynamic library error, you can try it yourself.
