GCC 4.5.2 compile on solaris 10

[Vincent]

Wondering if anyone has tips to help get a clean 64-bit build of gcc
4.5.2 on Sparc for Solaris 10? Or pointers to where I might look?

I've been noodling around with trying to use the /usr/sfw/bin/gcc and
Sun Studio 12.2 for about a day now. Latest attempt has configure
line like so:
/tank/src/gcc-4.5.2/configure CC=cc CXX=CC CFLAGS=-m64 CXXFLAGS=-m64 --
build=sparc-sun-solaris2.10 --with-gmp=/ucd --with-mpfr=/ucd --with-
mpc=/ucd --prefix=/ucd --with-gnu-as --with-as=/usr/sfw/bin/gas --
without-gnu-ld --with-ld=/usr/ccs/bin/ld --enable-shared --enable-
languages=c,c++

and this produces ELFCLASS 64 errors like so:

cc -g -DIN_GCC -DHAVE_CONFIG_H -DGENERATOR_FILE -o build/genmodes
\
build/genmodes.o build/errors.o ../build-sparc-sun-solaris2.10/

Have built all requisites from recent source. Used the 32-bit /usr/
sfw/bin/gcc and oddly seems I am ending up with 64-bit libraries. I'd
like in the end to have a complete 64-bit set of tools, but can't get
so far as building a 64-bit gcc on this platform to achieve that.

Why would you want to do this? Even if the compiler binary is 32-bit,
it is able to generate 32 and 64-bit code just fine.

I think you're missing --target=sparcv9-sun-solaris2.10. --build above
is wrong, too: your build compiler creates 64-bit code.

Note that it's a looong time I've tried this myself.
