Addendum:
I am using a x64 Kernel.
Does it matter?

Thanks for your support.

Unfortainly it din'twork for me.
I patched and recompiled and installed xenomai and my app,
but i have still the same error.

Have you got another idea, or need some other informations from my side?
You may want to trace your app with gdb, configuring with
--enable-debug=full, then single-stepping in rt_pipe_create() to
pinpoint the failing call in there.

Hello,

i try to switch with my working project from Xenomai 2.6 to 3.0rc
Cobaltusing the native/alchemy skin.

Creating tasks,etc. seems to works fine.

If i try to open a pipe from the realtime taks using rt_pipe_create it
returns with the error -88.
This is -ENOTSOCK, you can check all error codes there:
/usr/include/asm-generic/errno-base.h
/usr/include/asm-generic/errno.h

ENOTSOCK is not raised by the alchemy API, so this must be a syscall
taking the wrong route to the glibc in the core lib.
Please try this patch:

Has anything changed handling pipes in 3.0?
