nios2-linux-uclibc-gcc: 权限不够

Hi,all,

I build the kernel according to hippo.

When I execute "make",this err appears:

/bin/sh: line 1: nios2-linux-uclibc-gcc: command not found

make[1]: execvp: nios2-linux-uclibc-gcc: 权限不够

make[1]: Entering directory `/home/w/uClinux-dist-test/linux-2.6.x'

make[1]: execvp: nios2-linux-uclibc-gcc: 权限不够

Could anyone give some advice?
