KSYMS hard problem...

Hi everyone,

I'm using RTAI 24.1.8 with LTT 0.9.5pre6 on a 2.4.16 kernel (patched for
RTAI and LTT, of course)
with GCC 2.95.3. My goal is realize a real-time environment to work on a
CANopen fieldbus network; I
have a HILSCHER CIF-50 master card with Linux driver v2.100. Driver are load
as module (cif.o module).

I have mounted RTAI-LTT system and everything is ok, and the same for my can
bus network without
real-time. Now I must integrate the two worlds, so I write a user space
program using LXRT, and there
are no problems at compiling time, but when I run my aplication, I receive
the messages that I paste
below.

They are very strange because I have no error at compile time but many, for
examples, undefined
symbols a run time also on "printf" or puts "command"....and then, what is
"KSYMS line 1270" that
appears so many times?

Google search only find "ksyms" linux command, that returns kernel exported
symbols...

Can you say me something usefull? Also know what is KSYMS error is very
important for me!

Thank you very much.

Valerio.
