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
If I try using the unpatched host Linux version (2.4) I get the
following error message from
Xenomai configuration:
...
checking for Linux build tree... /lib/modules/2.4.21-32.EL/build (kernel
2.4.21-32.ELcustom)
checking for Linux source tree... /lib/modules/2.4.21-32.EL/build
checking for interrupt pipeline extension... configure: error: No
interrupt pipeline extension enabled in your kernel.
You need to apply an Adeos patch first.
make: *** [config.status] Error 1
Should I:
1. Try compiling with my patched Linux 2.6 - won't I have problems
running programs
compiled for Linux 2.6 on Linux 2.4?
2. compile Xenomai without Simulator support and then try installing the
simulator separately?
BTW when I try to install the simulator separately:
I ran sim/configure it passed and so did make and make install of the
simulator directly in sim directory, but when I tried to compile the
demos with gcic (make sim) I received the error message:
"gcic:instrumenter/compiler is missing -- please check your
installation."
So I thought this might not be the correct way to do it. Maybe I should
continue on this
road?
3. Something else?
I'm new to Xenomai and Linux so excuse me if I'm missing something
basic.
I appreciate your help!

Hi,
I'm trying to build Xenomai 2.0.1 with MVM support.
My target board is PPC and I use patched Linux 2.6.13.4 with it +
Xenomai 2.0.1 , cross compiled with the flags: ARCH=ppc
CROSS_COMPILE=ppc_82xx:
The simulator is a _host_ based tool, not a target one, so
you don't
want to cross-compile it for your target, it's a native compilation
from and for your build system. Make sure to read sim/README to get
the software package deps, then select the simulation build in the
config menu, and specify a valid path to a GCC-2.95.3
archive as specified.
While you are at it, also make sure to read
sim/doc/mvm-manual.txt to get a detailed explanation about
what the simulator does and how it does it. It's an
event-driven simulation engine working at source code level,
not a CPU emulator.
