本文介绍了一个用于构建跨平台libmp3lame静态库的Shell脚本。该脚本使用Xcode 4.3及iOS 5.1编译器针对不同架构（i686, armv6, armv7）进行编译，并最终通过lipo工具合并为一个通用库文件。适用于在模拟器或真实设备上使用。

I used this shell script to build a universal libmp3lame.a file. Note this uses Xcode 4.3 paths and iOS 5.1 compilers.

#!/bin/bash

SDK_VERSION="5.1"

mkdir build

function build_lame()
{
    make distclean

    ./configure \
        CFLAGS="-isysroot /Applications/Xcode.app/Contents/Developer/Platforms/${SDK}.platform/Developer/SDKs/${SDK}${SDK_VERSION}.sdk" \
        CC="/Applications/Xcode.app/Contents/Developer/Platforms/${SDK}.platform/Developer/usr/bin/gcc -arch ${PLATFORM}" \
        --prefix=/Users/mcrute/Desktop/lame \
        --host="arm-apple-darwin9" \
        --disable-shared \
        --enable-static \
        --disable-decoder \
        --disable-frontend

    make
    cp "libmp3lame/.libs/libmp3lame.a" "build/libmp3lame-${PLATFORM}.a"
}

PLATFORM="i686"
SDK="iPhoneSimulator"
build_lame

PLATFORM="armv6"
SDK="iPhoneOS"
build_lame

PLATFORM="armv7"
build_lame

lipo -create build/* -output build/libmp3lame.a

Take the libmp3lame.a file from build along with the lame.h file from the include directory and drop them in your Xcode project and you should be ready to use lame in either the simulator or a real device.
