Hi Graham, Hi Scott;

Thanks for your help for cross compiling.

though.

I have pgcc-2.91.66 (egcs-1.1.2 release) and I founded
a gcc-2.95 tar file but I have problem with the
./configure command (system can't find any sources in
. or ..).
I see you work on a pentium station and I would have
known how you have configured your machine.
Where can I find the last binutils and gcc release and
how install them (is there specifics command other
than --target=powerpc-linux and --with-newlib)?
Which modif must I make in the spec files?

I don't realy understand which role play this makefile
and what is ADB?

Thanks in advance for your help.
Good Day
