有些程序在ubuntu 14.04 64bit上不能成功运行，比如arm-none-linux-gnueabi安装成功了，但运行arm-none-linux-gnueabi-gcc -v，出现:

 
 

  
  
1
 
 
bash: /opt/arm-2014.05/bin/arm-none-linux-gnueabi-gcc: No such file or directory

此时需要安装ia32-libs:

  
  
1
 
 # sudo apt-get install ia32-libs

如果找不到ia32-libs，需要做如下处理：

sudo -i
apt-get install -f
apt-get update
apt-get upgrade




 
 


  
  
1
  
  
2
  
  
3
  
  
4
  
  
5
 
 

要等待一段时间进行下载安装，安装成功后建议再还原：
  
  

   
   
1
   
   
2
   
   
3
  
  
再去运行需要32位库的程序，就会发现可以运行了。
# sudo -i
# cd /etc/apt/sources.list.d
# echo "deb http://old-releases.ubuntu.com/ubuntu/ raring main restricted universe multiverse" >ia32-libs-raring.list
# apt-get update
# apt-get install ia32-libs sudo apt-get install lib32ncurses5 lib32z1 # rm /etc/apt/sources.list.d/ia32-libs-raring.list
# exit
