ubuntu12.04下装个软件，提示没有libSM.so.6库

ubuntu12.04下装个软件，提示没有libSM.so.6库，我查看依赖库，提示如下：

    libSM.so.6 => not found
libICE.so.6 => not found
libXrender.so.1 => not found
libfontconfig.so.1 => not found
libfreetype.so.6 => not found
libXext.so.6 => not found
libX11.so.6 => not found

可是我用sudo apt-get install libSM.so.6安装不成功，请问应该怎么解决，谢谢。

安装32位支持包ia32-libs即可
sudo apt-get install ia32-libs

sudo apt-get install libsm6:i386
