Red face difficulty in compiling the uClinux for lpc2478 ARM7TDMI using ubuntu9.04

Hi all,

I tried to compile the uClinux for the lpc2478 ARM7 controller using

make menu config.

After that i used the make command and I got the following errors and the output.

As you can see from the following message
/bin/sh: arm-linux-gcc: not found
you don't have an ARM cross compiler toolchain. Get one from uClinux site
