[Xenomai-help] problem with trivial-periodic.c example

[Thomas Häberle]

Hello!

I am running Xenomai 2.3.5 on my MPC5200S on a STK52xx with a Linux 
2.4.25-DENX kernel (cross-compiling to the target).

When I try to compile the "trivial-periodic.c" example with
 >>> $ ppc_6xx-gcc SimpleTask.c -I $XENOINSTALL/include -L 
$XENOINSTALL/lib -o SimpleTask -Wall

I get the following:
 >>>
/tmp/ccwxJiOz.o(.text+0x30): In function `demo':
: undefined reference to `rt_task_set_periodic'
/tmp/ccwxJiOz.o(.text+0x34): In function `demo':
: undefined reference to `rt_timer_read'
/tmp/ccwxJiOz.o(.text+0x4c): In function `demo':
: undefined reference to `rt_task_wait_period'

/tmp/ccwxJiOz.o(.text+0x188): In function `main':
: undefined reference to `rt_task_delete'
collect2: ld returned 1 exit status
<<<

Aren't the functions used in the example in the libraries in the 
"$XENOINSTALL/lib" directory?
Or do I have to tell the compiler and/or linker about any of the Xenomai 
source paths to get this working?

Thanks & Greetings,
Thomas

Please use the Makefile in that directory to learn how to build it. You
may need to define DESTDIR as well.

Wolfgang.
