Original question:
-----------------------------------------------------------------------
Hello everybody,
i've installed the Sun Workshop Compiler 5.0 and now I'm trying to compile some
programs in 64-bit mode for Solaris 7 (machine is an Enterprise 250).
Compiling with "-fast -xtarget=ultra -xarch=v9a" is OK, but at the linking
stage I get the following error:
ld: fatal: file ssh.o: wrong machine class
# file ssh.o
ssh.o: ELF 64-bit MSB relocatable SPARCV9 Version 1, UltraSPARC1
Extensions Required
can anybody give me a hint what the problem is?

Yes, we've installed the 64 bit version of the OS.

That's it! I've gone through the "ld" manpage but haven't found a hint like
this. Instead i found the following statement in the manpage:
There is no specific option that tells ld to link 64-bit
objects; the class of the first object that gets processed
by ld determines whether it is to perform a 32-bit or a
64-bit link edit.
I've set LDFLAGS to -xarch=v9a, rerun the configure script and the compiling
and linking worked!
Thank you both,
