Is there a way I can alter the gcc/g++ and gfortran behavior so that it always
creates 64-bit binaries on Solaris? I know you can do this with the -m64 flag,
but unfortunately Sage
http://www.sagemath.org/
unsets CFLAGS in places. There is over 260 MB of source code, and fixing it all
is a real pain. I've tried creating a wrapper script, which gets called instead
of the real gcc, but some bits of the source code simply wont compile like that.
I'm using gcc 4.3.4
drkirkby@hawk:~$ gcc -v
Using built-in specs.
Target: i386-pc-solaris2.11
Configured with: ../gcc-4.3.4/configure
--prefix=/usr/local/gcc-4.3.4-GNU-assembler-Sun-linker
--with-as=/usr/local/binutils-2.20/bin/as --with-ld=/usr/ccs/bin/ld
--with-gmp=/usr/local --with-mpfr=/usr/local
Thread model: posix
gcc version 4.3.4 (GCC)
The oupput of the specs file is below, but I'm not sure where I would need to
add the -m64's, or if they could be added.
