ios - 为 iOS 和 gas-preprocessor.pl 编译 ffmpeg

Question

我想为 iOS 编译 ffmpeg。我之前做过几次。但现在我在全新的 Mavericks 和 configure 我总是得到

Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
GNU assembler not found, install gas-preprocessor

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solving the problem.

我安装了当前的 Xcode。还冲泡。和电流 gas-preprocessor.pl ( https://github.com/yuvi/gas-preprocessor ) 在 usr/bin以及 usr/local/bin .

在 perl /usr/bin/gas-preprocessor.pl gcc我收到 Unrecognized input filetype at /usr/bin/gas-preprocessor.pl line 33.
此配置有效:

./configure \
--extra-cflags='-arch arm64 -mios-version-min=7.0 -mthumb' \
--extra-ldflags='-arch arm64 -mios-version-min=7.0' \
--enable-cross-compile \
--arch=arm64 \
--target-os=darwin \
--cc=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang \
--sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk \
--prefix=arm64 \
--disable-doc \
--disable-shared \
--disable-everything \
--enable-static \
--enable-pic \
--disable-muxers \
--enable-muxer=flv \
--disable-demuxers \
--enable-demuxer=h264 \

--enable-parser=h264 \

--disable-decoders \
--enable-decoder=h264 \
--enable-decoder=pcm_s16le \
--disable-protocols \
--enable-protocol=rtmp \
--disable-filters \
--disable-bsfs

此配置在上面抛出错误(未找到 GNU 汇编器，安装气体预处理器):

./configure \
--cpu=cortex-a8 \
--extra-cflags='-arch armv7 -mios-version-min=7.0 -mthumb' \

chmod +x gas-preprocessor.pl做到了!
