compiler-errors - 为 FFMPEG 编译 libvpx 时出现编译错误

Question

我正在我的 64 位 Ubuntu 14 机器上编译 FFMPEG。一切都编译得很好，除了 libvpx 库，它不断抛出错误:

[AS] vp9/common/x86/vp9_subpixel_8t_ssse3.asm.o
vp9/common/x86/vp9_subpixel_8t_ssse3.asm:856: warning: label alone on a line without a colon might be in error

make[1]: *** [vp9/common/x86/vp9_subpixel_8t_ssse3.asm.o] Error 1
make: *** [.DEFAULT] Error 2

我遵循了这个指南: https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu
我不知道这个错误是什么意思，但是在某处读到用 NASM 编译 libvpx 被破坏了，但我不知道如何编译它。安装 1.2 或 1.1 版没有任何区别。有任何想法吗？

用 Yasm 编译它就可以了:

PATH="$PATH:$HOME/bin" ./configure --prefix="$HOME/ffmpeg_build" --disable-examples
PATH="$PATH:$HOME/bin" make

假设 Yasm 在主目录中编译
