iPhone SDK 4.3 libav编译问题

我遇到了奇怪的问题。我安装了iPhone SDK 4.3和xCode 4，现在我无法从ffmpeg为ARMv6架构编译libav。这是我编译它的脚本（适用于iPhone SDK 4.2）： 
./configure 
--disable-doc --disable-ffmpeg --disable-ffplay --disable-ffserver --enable-cross-compile 
--enable-encoder=rawvideo 
--enable-decoder=h264 
--enable-decoder=mpeg4 
--enable-encoder=mjpeg 
--enable-muxer=rawvideo 
--enable-demuxer=h264 
--enable-parser=h264 
--enable-cross-compile 
--arch=c 
--target-os=darwin 
--enable-libopencore-amrnb --enable-libopencore-amrwb 
--cc=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/arm-apple-darwin10-gcc-4.2.1 
--as='gas-preprocessor/gas-preprocessor.pl /Developer/Platforms/iPhoneOS.platform/Developer    /usr/bin/arm-apple-darwin10-gcc-4.2.1' 
--sysroot=/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk 
--cpu=arm1176jzf-s --extra-cflags='-arch armv6' --extra-ldflags='-arch armv6'

make clean
make
因此我得到了库文件，但是当我用lipo -info命令检查它时，它显示库是为i386架构编译的。 也许有人面临这样的问题？请帮帮我。 谢谢。

    更新的帖子 这是一个更新的脚本，删除armv6，添加armv7s，使用iOS 6.0 SDK，并修复了对
    lipo
    工具的更改问题。确保你拥有最新的

    原帖 这将为armv6，armv7和i386架构构建ffmpeg静态库，并将它们组合成iOS 4.3（iPhoneOS4.3和iPhoneSimulator4.3）的胖（通用）文件：
