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 $XENOINSTALL/lib -o SimpleTask -Wall I get the following: >>> /tmp/ccwxJiOz.o(.text+0x30): In function `demo': : undefined reference to `rt_task_set_periodic' /tmp/ccwxJiOz.o(.text+0x34): In function `demo': : undefined reference to `rt_timer_read' /tmp/ccwxJiOz.o(.text+0x4c): In function `demo': : undefined reference to `rt_task_wait_period' /tmp/ccwxJiOz.o(.text+0x50): In function `demo': : undefined reference to `rt_timer_read' /tmp/ccwxJiOz.o(.text+0x160): In function `main': : undefined reference to `rt_task_create' /tmp/ccwxJiOz.o(.text+0x178): In function `main': : undefined reference to `rt_task_start' /tmp/ccwxJiOz.o(.text+0x188): In function `main': : undefined reference to `rt_task_delete' collect2: ld returned 1 exit status <<< Aren't the functions used in the example in the libraries in the "$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
