[Xenomai] Xemomai 3 - posix demo programs don't seem to be loading the right socket program.

[Xenomai] Xemomai 3 - posix demo programs don't seem to be loading the right socket program.

[Glen Wernersbach]

Hi All,

Fooling around with Xenomai 3 RC4. I can get the TestSuite to work but when
I run any of the standard posix demo examples I get the following error:
./bufp-readwrite 
socket 1: Address family not supported by protocol
socket 2: Address family not supported by protocol

Looking on the web this would indicate that the wrapper instruction is not
in the linker flags but it is. I tried building my own copy just to make
sure the wrapper was included but got the same error.
make
gcc -o RsConMain RsConMain.c -I/usr/xenomai/include/cobalt
-I/usr/xenomai/include -D_GNU_SOURCE -D_REENTRANT -D__COBALT__
-Wl,@/usr/xenomai/lib/cobalt.wrappers   -L/usr/xenomai/lib -lcobalt
-lpthread -lrt   

Any ideas?


Glen

I do not think "RsConMain" is a "standard posix demo example", or I
do not know what you mean by that. Anyway, providing the source of
the code you compile would allow us to help you instead of making
educated guesses. But the obvious question is: do you have the
support for the socket family you are trying to use enabled in the
kernel configuration?

Giles,

RsConMain was just a copy of  the bufp-readwrite demo program so I could
fool around with the make file to see if I could prove the wrapper was
loading. The code is the standard unmodified demo of the bufp-readwrite
demo example.

As it turns out as you suspected, for the standard demos that are
installed to work, you must go in and change the Xenomai kernel setting
RTIPC Protocol Family from its default value of excluded/Off and change to
an included/On setting.

Once that was done all of the demo programs and my copy worked just fine.
