Problem with eclipse, yagarto and LPC2148 test project

Hi,

I wanted to check all settings of eclipse and yagarto with this LB2148 
test project.
http://www.yagarto.de/howto/examples/index.html
I configured everything as it is described on yagarto.de. No changes 
where done in the files of this project.
After making the project, I got the error:

Description  Resource  Path  Location  Type
make: *** [test_ram.elf] Error 1  LPC2148pro    line 0  C/C++ Problem

Where can be the problem?
I also checked some other projects and got the same error, so it should 
be anywhere in the eclipse settings or ...?
I use yagarto from 23.12.2009 and eclipse is also the newest.

Possibly its a trivial error but I am very new to ARM and GCC tools.

Thank you
Max
