Hi Philippe,
Do you think I should wait for the v2.1 to be released
or is it stable enough To start playing with it now?
If we are still talking about the simulator, this is a rather mature
piece of code since 2000 or so. Actually, it has been adapted from an
old RTOS simulator project I recently moved to GNA:
www.gna.org/projects/carbonkernel.
Thanks a lot for all your help!
Sarit.

Hi Philippe,
I did read the files. What I don't understand is how to build the
Xenomai With Simulator support?
When I build Xenomai without simulator support - everything
works just
fine (crossed compiled to work on PPC with Linux 2.6.13.4).
As soon as I mark Simulator->Minute Virtual Machine I get
that error
(X11 library..).
I understood from reading previous mails on the internet
that I should
be able to build the MVM on my host computer which is NOT
patched by
Adeos (RHEL3.0 Linux on i686) through Regular Xenomai
CROSS_COMPILING
and installation.
Try this:
- Build your target system first without the simulator using
cross-compilation for ppc. Let's say that you installed the results
under /usr/realtime, which is the default.
- Then, build the simulator separately for the host:
$ mkdir sim-build && cd sim-build
$ .../xenomai/sim/configure --with-xeno-dir=/usr/realtime
--with-gcc-tarball=/something/gcc-2.95.3.tar.bz2
$ make install
Everything compiled fine, but when I tried to compile the
native demo
for the Simulator I received the following error:
cd .../skins/native/demos
[demos]$ /usr/realtime/bin/gcic -o satch_s.o -c satch.c -g -I

Gah. Ok, my mistake. Since you are cross-compiling for your
target, you need to have two Xenomai installations, once for
the ppc target to run the real stuff, another one to run the
virtual simulation environment for the x86 host.
So, ...
- Configure and cross-compile Xenomai for ppc without
simulation support for installing to /opt/nfsroot
- Configure and compile Xenomai natively for x86 with
simulation support for installing to, e.g. /opt/local
This way at least, you won't need to build the simulator
apart, it will be built as part of the second step. Most of
the native x86 support won't be used (aside of the simulator,
of course), but at least, this will work. On the host, you
will need to set your PATH and LD_LIBRARY_PATH to
/opt/local/bin, and /opt/local/lib respectively, so that the
simulation libs and tools are found.
The #warning won't go away though; only v2.1 gets rid of this
by avoiding any kernel header inclusion in user-space. Debian
systems would not bother you with this (at least sarge
doesn't), but RH actually do.
