ios - iFrameExtractor 无法使用 XCode 4.3.3 和 iOS 5.1 为 armv7 构建库

Question

我已经从这个链接下载了使用 XCode 4.3.3 for iOS 5.1 构建的代码 - https://github.com/lajos/iFrameExtractor
我能够使用 build_universal 脚本成功地为 FFmpeg 构建库。但它总是为 X86_64 架构构建库。用 lipo -info 命令检查。

还尝试了链接中的构建脚本 - http://stexgroup.com/blog/ffmpeg-for-iphone-ios-xcode4.3-build-script .它还为 X86_64 架构构建库。

我根据这篇文章更改了脚本 - problem compiling ffmpeg for iFrameExtractor

但没有什么对我有用。

armv7 [iFrameExtractor] 的构建脚本如下

./configure \
--disable-bzlib --disable-doc \
--disable-ffmpeg --disable-ffplay \
--disable-ffserver --disable-mmx \
--cc=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc \
--as='gas-preprocessor/gas-preprocessor.pl /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc' \
--enable-cross-compile --target-os=darwin \
--arch=arm --cpu=cortex-a8 --enable-pic \
--sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk \
--extra-ldflags="-arch armv7 -    L//Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk/usr/lib" \
--extra-cflags="-arch armv7"

考虑到同样的事情对其他人有用，谁能指导我可能是什么问题？

使用以下脚本，我可以构建库。这些脚本是 Far Pointer 在此链接中共享的脚本的修改版本 - problem compiling ffmpeg for iFrameExtractor

armv6

#!/bin/tcsh -f

if (! -d armv6) mkdir armv6

rm lib/*.a

cp i386/*.a lib/

现在的问题是所有脚本都为 armv6 架构构建库。有没有人遇到这样的问题？
