µclinux ,problem of script checkout

This is the error :

nios2-linux-gnu-gcc: command not found; perhaps you need to fix your PATH?

Did you followed the guide step by step at http://www.nioswiki.com/linux ?

In the Quick start page, the first thing you have to do is to set up the path to the toolchain :

PATH=$PATH:~/nios2-linux/toolchain-mmu/x86-linux2/bin

If you don't want to add it to your .bash_profile ok but then you have to set up the path in a terminal, bash. This command is useful to find program for the cross-compilation.
