I have gcc installed. as and ld are the ones from SunCC; I checked 
sunfreeware.com to download a new version of gcc, but they say that "it 
was compiled to use the SUN assembler and loader usually in 
/usr/ccs/bin", i.e. the same as my current gcc installation. Maybe 
that's the way it is supposed to be for Solaris.

as, ld, cc1 point now to the native ones as you guys suggested. RTEMS's 
configure script fails because it can't find a crt0.o file.
I don't have any crt0.o on my computer. But I do have libc.a and other 
files called crt1.o crti.o crtn.o
Is it supposed to be included in binutils? native/crosscompiler? where 
do i get a crt0.o?

May I ask why if I want to compile for my target, the native as and ld 
are to be used?

thank you,
