how to use "msgget" in nios2 uclinx?

hi:

I use function ret = msgget(KEY_MQ_CORE, IPC_CREAT|0660); make successed.

After exec, but the return value is -1

I want to use cmd "IPCS" to check the ipc ID. but shell return: not found.

http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif

How can I do? The same function "msgget" used in other uClinx os is OK.

Why failed in nios2 uClinux? Why the cmd "IPCS" not support nios2 linux?

Thanks a lot.

    I make ~/apps/mqueue but failed. So I rework the Makefile of mqueue .

    But I meet a question. If I want to use mqueue ,frist I must make ~/apps/mqueue/src to make libmqueue.a

    So I added "ar = nios2-linux-uclibc-ar&#39; id makefile.

    but in make process, the cc use gcc not nios2-linux-uclibc-gcc,so the libmqueue.a

    is wrong.

    Please look at download/mx140apps.diff, and modify the Makefile.
