[Xenomai] Using pipes in 3.0rc

[Xenomai] Using pipes in 3.0rc

[Registrierungen]

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.
XDDP/rpc ist activted in th kernel.
  I used this Makefile config:

XENO_CONFIG := /usr/xenomai/bin/xeno-config
CFLAGS := $(shell $(XENO_CONFIG) --skin=alchemy --cflags)
LDFLAGS := $(shell $(XENO_CONFIG) --skin=alchemy --ldflags)
CC := $(shell $(XENO_CONFIG) --cc)

Has anything changed handling pipes in 3.0?

What exacliy this error means?

Thanks

   Sascha

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:

[Registrierungen]

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.

Just a stupid question, you are sure you have RTIPC and XDDP enabled
in kernel configuration, right?

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

No, it does not. Do you plan to debug with gdb as I suggested?

Re: [Xenomai] Using pipes in 3.0rc

[Registrierungen]

Sure. i compiled xenomai as your suggestion.
Ive got a a little problem with my eclipse debug enviroment.
It still does not debug into the xenomai files at moment. so i will fix
it first and come back with new informations.

This is what you need to enable pipes with Alchemy:

Re: [Xenomai] Using pipes in 3.0rc

[Registrierungen]

Sorry for the late feedback.

I found the source where it goes wrong:

     if (poolsize > 0) {
         ret = __RT(setsockopt(sock, SOL_XDDP, XDDP_POOLSZ,
                       &poolsize, sizeof(poolsize)));
         if (ret)
             goto fail_sockopt;
     }

Hope there could be found a solution for me.

Those patches are present in -rc2, released a couple of days ago. You
should not bother with -rc1 anymore.

I tried with rc2, but now it returns with error 3 (not -3) ?
