此篇文章的环境:xcode6.1 sdk8.1
编译的版本:真机armv7 arm64

这两天在编译x264的库，按照网上的方法

一，x264库的编译
首先到http://www.videolan.org/developers/x264.html下载x264的库，然后解压。

打开shell，进入x264的目录，执行如下语句

CC=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc ./configure --host=arm-apple-darwin --sysroot=/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk --extra-cflags='-arch armv7' --extra-ldflags='-arch armv7 -L/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk/usr/lib/system' --enable-pic

make,make install;

发现，出现No working C compiler found.错误，原因是没有在/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc 下面找到gcc，因为上面的语句是在xcode4.2编译的，现在xcode6.1了，那个路径下没有gcc了，后来根据查找各种资料，各种尝试，希望遇到同样问题的不要走弯路，最后的命令如下：

armv7

CC=/Applications/Xcode.app/Contents/Developer/usr/bin/gcc ./configure --host=arm-apple-darwin --sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk --extra-cflags='-arch armv7' --extra-ldflags='-arch armv7 -L /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/usr/lib/system' --enable-pic --disable-asm

运行完了以后再运行make就可以找到libx264.a库

arm64

CC=/Applications/Xcode.app/Contents/Developer/usr/bin/gcc ./configure --host=arm-apple-darwin --sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk --extra-cflags='-arch arm64' --extra-ldflags='-arch arm64 -L /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/usr/lib/system' --enable-pic --disable-asm

运行完了以后再运行make就可以找到libx264.a库
