我试图在iOS6.1(armv7)上构建ffmpeg,当我尝试运行./configure时:
./configure --disable-doc --disable-ffmpeg --disable-ffplay
--disable-ffserver --enable-cross-compile --arch=arm --target-os=darwin --cc=/applications/xcode.app/contents/Developer/usr/bin/gcc --as='gas-preprocessor/gas-preprocessor.pl /applications/xcode.app/contents/Developer/usr/bin/gcc'
--sysroot=/applications/xcode.app/contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk
--cpu=cortex-a8 --extra-cflags='-arch armv7' --extra-ldflags='-arch armv7 -isysroot /applications/xcode.app/contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk'
--enable-pic
我收到以下错误:
/applications/xcode.app/contents/Developer/usr/bin/gcc无法创建可执行文件 . C编译器测试失败 .
有人可以在iOS6.1中提供正确的参数吗?

如果您认为configure出错了,请确保您使用的是Git的最新版本 . 如果最新版本失败,请将问题报告给irc.freenode.net上的ffmpeg-user@ffmpeg.org邮件列表或IRC #ffmpeg . 包括configure生成的日志文件“config.log”,因为这将有助于解决问题 .

您正在使用...
这对armv7来说是错误的,你应该这样做......
将上面的内容更改为
arm-apple-darwin10-gcc-x.x.x
文件夹中的arm-apple-darwin10-gcc-x.x.x
版本 .同样,将gas-preprocessor的目标编译器更改为相同 .
另外,不要在你的
--extra-cflags
中放置-arch armv7
,你不需要它,你可能会收到错误:unrecognized command line option "-arch"
