【Linux】nasm/yasm not found

背景

在配置FFmpeg的时候，如下：

cd ~/Git
git clone https://github.com/FFmpeg/FFmpeg.git
cd FFmpeg

mkdir -p $(pwd)/build_x64_release_shared 
./configure \
 --prefix=$(pwd)/build_x64_release_shared \
 --disable-static \
 --disable-stripping \
 --disable-doc \
 --enable-shared

遇到nasm/yasm报错如下：

root@3fbaf54f21b4:/path/FFmpeg# ./configure  --prefix=$(pwd)/build_x64_release_shared  --disable-static  --disable-stripping  --disable-doc  --enable-shared
nasm/yasm not found or too old. Use --disable-x86asm for a crippled build.

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
[e-mail] mailing list or IRC #ffmpeg on irc.libera.chat.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.
root@3fbaf54f21b4:/path/FFmpeg# 

分析：yasm是汇编编译器，ffmpeg为了提高效率使用了汇编指令，如MMX和SSE等。
所以系统中未安装yasm时，就会报上面错误。

如果不需要yasm也可以：

./configure --disable-x86asm

解决办法

apt-get install yasm
