1、在网上找到相应的C源码
2、如果带有makefile文件的
3、直接在shell里面执行
i386:
CC=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc ./configure --host=i386-apple-darwin --sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator9.3.sdk --extra-cflags='-arch i386' --extra-ldflags='-arch i386 -L/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator9.3.sdk/usr/lib/system -arch i386 ' --disable-asm --enable-shared --enable-static --disable-asm
不同xcode和系统版本,要修改iPhoneSimulator.platform、iPhoneSimulator9.3.sdk、/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc,这几个配置
最后
make&&make install
合并静态库
lipo -create ./aall/libx264.a ./x86_64/libx264.a -output libx264.a
查看静态库
lipo -info libx264.a
Architectures in the fat file: libx264.a are: i386 armv7 armv7s x86_64 arm64
