Error during make zImage

Hi,

Stating up with a project, I am prepering a first image for testing.

I am following the instruction from

buildrootguide (http://nioswiki.jot.com/wikihome/operatingsystems/buildrootguide).

Currently at step 5, just after succefull complition of: "make menuconfig".

(ARCH=nios2nommu CROSS_COMPILE=nios2-linux-uclibc- are defined as part of my environment)

I encounter the following during make zImage:

$ make zImage

Any ideas?
