1) Are you trying to build for big- or little-endian? Because that 
command is from the big-endian section of the page.

2) Do you have a standard /etc/fpc.cfg?

3) What version of the FPC compiler etc. are you using?

4) Are you using the sources recently checked out from subversion?

5) Have you build binutils of the recommended version?

6) Immediately before that command, what is the value of the PP shell 
variable?

7) To get context, what is the last line of explanatory text immediately 
before you've entered that command?

8) Please could a German-speaker comment on those error messages?

I admit to being slightly stumped by this, because I specifically noted 
the commands in the second part of that page (for big-endian MIPS) to 
illustrate that transcription from the first part (little-endian) 
worked. The only thing that you need to be *careful* *about* is the 
*directory* *structure* - but I'd hoped that was pretty obvious- and in 
the case of big-endian the name of the directories that are storing the 
unit files.

I'm by no means experienced at this, and if I can do it I don't see why 
you shouldn't be able to.
