make full gcc unsuccessful for powerpc on Solaris (target=powerpc-elf), also linking with 'core' target gcc unsuccessful

["Bertin, Philippe" <philippe dot bertin at barco dot com>]

Hi all,

"An accident never comes alone", one sometimes says :(  Well, what am I to
do with this situation in which
1. I can't, apparantly due to problems in libiberty, upgrade (with the C
run-time libraries) my 'core' gcc (version 2.95.3, for target powerpc-elf on
Solaris2.6.0) after having built newlib(1.9.0) - see first extract of error
messages at the end -, AND
2. I can't link the normal runtime libraries (and another library) into a
basic program without linker errors - see second extract at the end -
neither.

So I'm trying to compile and link using the core-gcc, libc and another
library. Having looked at archives of several newsgroups, and having tried
several possible solutions (e.g. copying crt0.o to the current directory, or
using several rpath-options), I stay stuck at the same point. Could anyone
say what exact options I should give to the linker (note : core -cross-gcc
is used, a full -cross-gcc couldn't be made as I just mentioned) so that I
can be sure not to miss any linker directory and/or any file that should be
found ? The program I'm compiling/linking is a basic main with a basic
printf- statement, so I shouldn't need any much more than libc.a; my command
line read :

powerpc-elf-gcc
-Wl,-L~/cross/newlib-1.9.0/powerpc-elf/newlib,-L$prefix/powerpc-elf/lib,-L.,
-lgp-new,-lc test.c

Am I missing something here ? (what's the logic with crt0.o, BTW) Should I
continue looking for setting the environment variables GCC_INCLUDE_DIR,
GPLUS_INCLUDE_DIR, LOCAL_INCLUDE_DIR, CROSS_INCLUDE_DIR or TOOL_INCLUDE_DIR
(if yes, what exact settings should these be set at) ?

Regards,

Philippe Bertin.
