You need to use GCC 3.1: 3.0 and earlier do not properly support the
64-bit Solaris ABI.

GCC 3.1 is currently in development but is in a bug-fixing development
phase. You'll have to fetch source from CVS (as described on the GCC
website) or obtain a development source snapshot. You don't need any
special configuration options: it will, by default, built a 32-bit
compiler and both 32- and 64-bit libraries.

To generate 64-bit objects use option '-m64'.

64 bits code generation

[Celestino Gómez Cid]

Hello,

	I'im using the gnu g++ compiler running in a UltraSparc solaris 2.7, and I
would like to know, please, if it is possible with any of the versions of
the compiler to generate 64 bit, binary files (similar to the -v9 option in
the compiler from SUN).

	There is a compiler option -mcpu=v9 but I'm not sure that has the same
results as I get an error:

/usr/ccs/bin/as: "/var/tmp/ccax7Qbi.s", line 33: error: cannot use v8plus
instructions in a non-v8plus target binary
/usr/ccs/bin/as: "/var/tmp/ccax7Qbi.s", line 36: error: cannot use v8plus
instructions in a non-v8plus target binary

Is it possible to generate 64 bits objects ? If it is,  which version shall
I use ? do I need to add some configuration options when installing the
compiler ?

Thanks very much.
