Why is Program.system == Null????

Hi,

when i try to compile with xdc tool, i get the error :

codecs.videnc_copy.close() ...
ti.sdo.ce.bioslog.close() ...
ti.sdo.ce.osal.close() ...
error: xdc.cfg.Program: "C:/Programme/TI/bios_5_21_03/xdctools/packages/xdc
/runtime/package.xs", line 59: xdc.cfg.Program : the target module ti.sdo.c
e.CERuntime is present, but Program.system == null

My target is set to C64P, the user.bld and xdcpath.mak are right, i think... ;)

I'm using WinCE 6.0 and the dm6446.

What could be the reason for this??

Thx :)
