Currently the focus on Sage it so build it in 32-bit on Solaris, not
64-bit. Ultimately, 64-bit would be the goal. The GNU compilers are
generally reckoned to present more problems on 64-bit SPARC than on
32-bit. Hence initially, we don't intend using 64-bit. I think the plan
is basically
1) Get it building reliably in 32-bit mode with gcc.
2) Works towards 64-bit and Sun compilers (not sure what order these
will come).
Inside Sage, 'ABI=32' is used as a configure option on Solaris. Look at
spkg-install and you will see:
build()
{
SAGE_CONF_OPTS="--enable-shared --disable-static"
case $UNAME in
SunOS)
if [ "$SAGE64" = "yes" ]; then
echo "Building 64 bit Solaris version"
ABI=64
else
ABI=32
fi;;
Darwin)
So far, no serious attempt at been made at 64-bit and I suspect that
would bring a lot more problems, especially while the GNU compiler is
used. But too many things would break if we switched to the Sun compiler.
