Thank you, that seemed to work.

However,
1) going on lazarus and choosing ppc386 as compiler, I got no errors 
(also the project in the "code" section of "compiler options" is set to 
i386).
2) the project compiles well
3) I fail during the link process with that error: "/usr/bin/ld: 
skipping incompatible /usr/lib/crti.o when searching for /usr/lib/crti.o"

The file /usr/lib/crti.o exists.

In the guide: http://wiki.lazarus.freepascal.org/Cross_compiling
something about a ld script was written, I created the scripts as 
indicated (plus chmod +x), but I have not launched them.

I have to do something related to this?
