hi

iam working with uclinux
i got errors while compilation..

help me to solve this

thanks in advance

The code with issues is not actually C, as far as I can see. This
newsgroup is about C not assembler.

You'd probably do better asking in a group or forum which is related to
the compiler (I presume it's gcc, so gnu.gcc or gnu.gcc.help may be
appropriate) or the software you're trying to build
(http://www.uclinux.org/maillist/ may be helpful).
