building a Lexer using flex and icc in the PASE-shell

Hi,

I'm trying to build a Lexer with flex and icc in the PASE-shell. I generate
a testprogram from a file named sum.l
with the command flex sum.l > sum.c. Then I have to change the ccsid from
the file sum.c with the command
setccsid 37 sum.c because the braces were changed to german umlauts. But if
I try to compile it with
icc -o sum sum.c -lfl I get following errormessages:

The same file works on linux and windows. I know that OS/400 doesn't
provide shared libraries like Unix.
 Have anyone a clue  how I get this work under OS/400?
