[ECOS] powerpc eabi installation and compilation

[Matthieu dot GIRARDIN at fr dot thalesgroup dot com]

Thanks a lot Andrew and Nick for your help.

As you suggested me, I created a new directory (a "clean" one) and I have no
problem any more. But I didn't succeed in compiling my application which had
no problem under Linux Synthetic Target (i386-elf-gcc)...

I think I forgot a option in my compilation line or maybe I have an error in
my installation but I don't see why.

Just under, you can see what I did with some comments... It's a good way to
summarize my installation and my compilation line.

My problems during compilation are at the end. If you can translate, explain
it to me, it would be great. Thanks

Thanks by advance.

Voilà pour l'installation d'eCos;
Aucun probleme n'est apparu.
La suite correspond aux tests que Nick m'a demandé.
Toutefois je n'ai plus de problème depuis que sur les conseils d'Andrew j'ai
tout réinstallé dans un répertoire clean
[ENG]
Done for eCos installation;
No problem.
Next you can see results of tests that Nick asked me.
But there is no problem any more since my new installation in a clean
directory as Andrew suggested me. Thanks

J'ai aussi compilé un autre eCos Psim à l'aide de configtool cette fois.
Il se trouve dans /opt/ecos.ppc/configurations/ppc.psim.auto
Je tente ensuite de compiler mon application qui ne générait aucune erreur
sous Linux Synthetic Target;
Les erreurs (ci-dessous) sont donc dues (pour moi) soit à ma réinstallation,
soit à la compilation powerpc-eabi...

I compiled too another eCos PPC version with configtool this time.
It's localised in /opt/ecos.ppc/configurations/ppc.psim.auto
I try then to compile my application which did no error under Linux
Synthetic Target;
Errors of ppc version (just under) can be explain only (for me) by my new
installation or by powerpc-eabi compil...
