mplayer 配置错误：共享 FFmpeg 需要 libavutil/x86/asm.h 标头

在 Ubuntu 14.04 中，我运行./configure --enable-gui --enable-xvid-lavc --enable-xv --enable-alsa安装mplayer，然后Checking for FFmpeg ....出现错误。cat config.log错误详细信息如下：

collect2: error: ld returned 1 exit status

我不知道发生了什么，请帮忙

答案1

如果您想mplayer从源代码构建，我会安装其所有构建依赖项：

sudo apt-get build-dep mplayer

答案2

实际错误是：

/usr/bin/ld: cannot find -lasound

我认为你需要安装libasound2-dev：

sudo apt-get install libasound2-dev

答案3

按照 Ubuntu 论坛上的这个指南操作可能是最简单的：

如何：在 Ubuntu 最新发布版本下构建 svn MPlayer

这将保证 MPlayer 和最新的 SMPlayer 能够正常工作且功能齐全...
