[sting sting]

Hello,
First Thnxs Ian Lance.

Second:

I took the "powerpc-*-elf" from the "INSTALL" folder
of the gcc where there are some docs in HTML about configuring .

Now  I made a separate folder for build, and ran from there
../gcc-3.3.2/configure --target=powerpc-elf

I got again the message:
Configuring for a i686-pc-linux-gnu host.
*** This configuration is not supported in the following subdirectories:
     target-libffi target-boehm-gc target-zlib target-libjava
    (Any other directories should still work fine.)

But again configure finished successfully; but in make I had passed the 
"Ada" stage and
got a different error this time
(I think it has to do with the assmebler)

if [ -f stmp-dirs ]; then true; else touch stmp-dirs; fi

Any idea?
any help will be appreciated.

sting

You are building a cross-compiler, so you need a cross-assembler.  gcc
didn't find a cross-assembler, so it tried to use the native assembler
on your system, which failed.

Building a cross-compiler is a slightly tedious exercise.  I'm afraid
I can't help you walk through it.  I think there are various FAQs out
there on how to do it.
