I'm getting this error when compiling the examples in the ipc folder

gcc -I/usr/xenomai/include -D_GNU_SOURCE -D_REENTRANT -Wall
-Werror-implicit-function-
declaration -pipe -D__XENO__ -I/usr/xenomai/include/posix
-Wl,@/usr/xenomai/lib/posix.wrappers -L/usr/xenomai/lib -lpthread_rt
-lxenomai -lpthread -lrt   -lrtdm -Xlinker -rpath -Xlinker
/usr/xenomai/lib  xddp-echo.c   -o xddp-echo

/usr/bin/ld: /tmp/cc4VCXFp.o: undefined reference to symbol
'pthread_sigmask@@GLIBC_2.2.5'
/usr/bin/ld: note: 'pthread_sigmask@@GLIBC_2.2.5' is defined in DSO
/lib/x86_64-linux-gnu/libpthread.so.0 so try adding it to the linker
command line
/lib/x86_64-linux-gnu/libpthread.so.0: could not read symbols: Invalid
operation
collect2: ld returned 1 exit status
make: *** [xddp-echo] Error 1

Is this a xenomai bug or glibc library bug?

Thanks

Danilo

Also,
if I remove the -lpthread flag the example compile successfully, but then
when I run it I get:

socket: Address family not supported by protocol

and this is the output of

nm -s ./xddp-echo

Linker wants to see references first, for pulling symbols. Does this help?

Thanks! now I can build the examples successfully, but at runtime I still
get the error:

You need to enable CONFIG_XENO_DRIVERS_RTIPC options in your kernel 
configuration, specifically CONFIG_XENO_DRIVERS_RTIPC_XDDP. If you 
enable them as modules, don't forget to load xeno_rtipc.ko.
