ARM工具链未与14.2 ISE一起安装

我有一个Linux Mint 12 64位客户端机器，我正在尝试安装14.2 EDK。
我已经解压缩Xilinx_ISE_DS_14_.2_p.28xd.3.0并运行xsetup。
我已按照安装步骤进行操作，并确保已检查ARM工具。
安装完成，我可以运行xsdk等。
但是，当我查看/opt/Xilinx/14.2/ISE_DS_EDK/gnu/arm目录未正确创建时。
现在我相信我可能必须在安装之前修改我的shell（我似乎记得在另一台机器上进行原始的14.1安装时读这个），但是对于我的生活，我找不到文档说我应该做什么改变
。
任何帮助将非常感激。
提前致谢！



以下为原文

I have a Linux Mint 12 64bit client machine and am trying to get 14.2 EDK installed on it.
I have unpacked Xilinx_ISE_DS_14_.2_p.28xd.3.0 and run xsetup. I have followed the installation steps and have made sure that the ARM tools are checked.

Installation completes and I can run xsdk, etc.

However when I look in /opt/Xilinx/14.2/ISE_DS_EDK/gnu/arm directory is not being created correctly.

Now I believe that I may have to modify my shell prior to installation (I seem to remember reading this when doing my original 14.1 installation on another machine), but for the life of me I cannot find the document to say what changes I should make.

Any help would be much appreciated.
Thanks in advance!
