報錯：

Neither yasm nor nasm have been found. See the prerequisites section in the README for more info.

這個只需要安裝yasm

有兩種方法

1）

yum install yasm

2)

wget http://www.tortall.net/projects/yasm/releases/yasm-1.2.0.tar.gz
tar zxvf yasm-1.2.0.tar.gz
cd yasm-1.2.0/
./configure
make
make install

還有個執行 ./configure後面後很多引數。依賴比較多。建議不需要的不要enable
