我已经成功地构建了libyuv.a库，但是当我运行configure-iPhone（https://code.google.com/p/siphon/wiki/VIdeoSupport）时我得到的日志告诉 libyuv 不可用并且视频支持被禁用。任何人都可以告诉我如何将 libyuv.a 文件链接到 configure-iPhone

Configurations for current target have been written to 'build.mak', and 'os-auto.mak' in various build directories, and pjlib/include/pj/compat/os_auto.h.
Further customizations can be put in:
- 'user.mak'
- 'pjlib/include/pj/config_site.h'
The next step now is to run 'make dep' and 'make'.
Done configuring for iPhoneOS6.1.sdk

你自己在建造 libyuv 吗？ 如果是这样，我也遇到了这个问题，不得不做：
ln -s /usr/local/include/libyuv/libyuv /usr/local/include/libyuv/libyuv/
或到您安装 Libyuv 的任何地方。
希望对您有所帮助，如果您仍在尝试使其正常工作。
