I have a problem while compiling my ARM programs..

This is the error i get after i click "make -all"

> "make.exe" all

-------- begin --------
process_begin: CreateProcess((null), arm-elf-gcc --version, ...) failed.
make (e=2): The system cannot find the file specified.

make.exe: *** [gccversion] Error 2

> Process Exit Code: 2
> Time Taken: 00:02


I have given the correct paths in the environment settings...

What could be the problem ?

And here are the contents of the "make" file

# Hey Emacs, this is a -*- makefile -*-
#
# WinARM template makefile
# by Martin Thomas, Kaiserslautern, Germany
# <eversmith@heizung-thomas.de>
#
# based on the WinAVR makefile written by Eric B. Weddington, Jörg
Wunsch, et al.
# Released to the Public Domain
# Please read the make user manual!
#
#
# On command line:
#
# make all = Make software.
#
# make clean = Clean out built project files.
#
# make program = Download the hex file to the device, using lpc21isp
#
# (TODO: make filename.s = Just compile filename.c into the assembler
code only)
#
# To rebuild project do "make clean" then "make all".
#
# Changelog:
# - 17. Feb. 2005  - added thumb-interwork support (mth)
# - 28. Apr. 2005  - added C++ support (mth)

Is that really what the error message says or have you truncated it. If
it is verbatim then what is the "...)" part? If you modified it before
posting - don't. Error messages contain information to help find faults,
you only make it harder by omitting that information.

It looks like it failed at the gccversion rule: @$(CC) --version

You should consider removing the @ so you can see what it is actually
trying to execute.

Well we have to take your word for it I suppose. Have you checked them
for this session (enter "set" or "path" from the command line). You
could be certain by adding the full path to the CC macro.

Thats the exact error message that i copy-pasted from the pn console..
Its not modified in any way..

I double checked the path.. its correctly entered. Checked it from the
command line too.. Could it be a version conflict ?

My apologies, on second look, I see that CreateProcess() has a long list
of parameters, I guess that's what the ... indicates. The first argument
of create process is the executable, but you have (null) which is a
problem.

What is the path to arm-elf-gcc? Some builds of make.exe have trouble
with paths containing spaces.

I made a couple of other suggestions (remove the @ so we can see the
command line, add the full path to the CC macro rather than rely on
environment variables). What were the results of that?

I guess you missed the point about "taking your word for it" - I
expected you to perhaps post the paths you had set. You should have
winarm\bin and winarm\utils\bin (at least).

I got around the problem... I downloaded a zip/rar file
(WinARM_utils_testing_20060719) from this site. It had some test files.
I replaced those from C:\winARM\utils\bin with these... Now it works
fine. Probably some problem with the make.exe file ?

Is the used OS MS Vista? Which files have been replaced in the utils/bin
directroy. What "test files" have been used for replacement?
