[Xenomai] Compiling testsuite and utils

[Eder Alves de Moura]

Dears,

I am starting with Xenomai and rt systems and I want to compile it for
a raspberry pi 2/3 and beaglebone black but first I compiled it to a
PC and, apparently it is working fine.

$ dmesg | grep -i xenomai
[    3.224489] [Xenomai] scheduling class idle registered.
[    3.224491] [Xenomai] scheduling class rt registered.
[    3.224515] [Xenomai] disabling automatic C1E state promotion on
Intel processor
[    3.224521] [Xenomai] SMI-enabled chipset found, but SMI workaround disabled
                         (see xenomai.smi parameter). You might encounter
[    3.224592] I-pipe: head domain Xenomai registered.
[    3.224916] [Xenomai] Cobalt v3.0.2 (Exact Zero)



But after install I could not compile the tools for xenomai, running

$ mkdir $build_root && cd $build_root
$ $xenomai_root/configure --with-core=cobalt --enable-smp --enable-pshared \
  --host=i686-linux CFLAGS="-m32 -O2" LDFLAGS="-m32"

I am receiving the following message

Did you check config.log?

Are you sure you have everything installed for gcc -m32 to work? I
mean, did you try to compile an "hello world" application with gcc
-m32 to see if the compilation works? Also, what is the point of
compiling in 32 bits mode, why not using a 64 bits kernel and
user-space?

Ok. This is a different issue. You are not answering my questions
though. So I am going to repeat them:
- do you really want to compile a 32 bits version of Xenomai?
- if yes, did you check that you have everything in place to do it,
by compiling a C language hello world command with gcc -m32?

Until you have answered these questions, any later attempt at
compiling xenomai is useless.

- do you really want to compile a 32 bits version of Xenomai?

no. I am not want to compile it to a specific 32 bits.

I want to run this program on my machine

The run configure without a --host or CFLAGS, or LDFLAGS. The
defaults should be fine.

The sources may be found here:
https://xenomai.org//downloads/xenomai/stable/xenomai-3.0.2.tar.bz2

When you extract them, the directory should be named
"xenomai-3.0.2".

You do not need to run autoreconf.

a C language hello world program, I mean.

I mean, please answer these questions, the right arguments to pass
to configure depend on the answer.
