RTEMS has a different view of resource usage control than Linux.  You
have to configure the maximum number of each object type you will use.
You need to look for an include of confdefs.h and make you define
the appropriate number of each object type required.  Here is an
example from c/src/tests/psxtests/psx01.

/* configuration information */

#define CONFIGURE_APPLICATION_NEEDS_CONSOLE_DRIVER
#define CONFIGURE_APPLICATION_NEEDS_CLOCK_DRIVER

#define CONFIGURE_MAXIMUM_POSIX_THREADS     2

#define CONFIGURE_POSIX_INIT_THREAD_TABLE

#include <confdefs.h>

See 
http://www.rtems.com/onlinedocs/releases/rtemsdocs-4.6.0pre5/share/rtems/html/c_user/c_user00375.html
for all the details.
