Hello friends,

  I am working on a project which has the short term goal of porting
Monta Vista Embedded Linux on a Intel PXA board (having ARM core). I
am facing the problem at the initial stage itself. I have installed
the Monta vista Linux on Windows platform.

   When i try to do make oldconfig (as per the kernel build guide) it
shows the warning

    /bin/sh: line 1: xscale_le-gcc: command not found.

 Although make oldconfig is successful. After that i try to do make
dep which gives me following error

720922@infva02366 /mykernel
$ make dep
/bin/sh: line 1: xscale_le-gcc: command not found
rm -f include/asm
( cd include ; ln -sf asm-arm asm)

make[2]: Leaving directory `/mykernel/arch/arm/tools'

make[1]: Leaving directory `/mykernel/arch/arm/tools'

Any idea why this is happening?
