Hello, i just built gcc 4.1.0 from sources. I'd like to be able to target
both 32 bit and 64 bit apps. I try to add the -m64 flag to a compile though
and i get:
hello.c:1: sorry, unimplemented: 64-bit mode not compiled in
what did i do wrong in the build? i didn't see anything about targetting
multiple configs.
My configure command is:
../gcc-4.*/configure \
--prefix=/tp/tools/gcc/4.1.0 \
--enable-shared \
--enable-threads \
--enable-tls \
--with-arch=pentium3 \
--with-tune=pentium4 \
--enable-__cxa_atexit \
--enable-languages=c,c++,fortran \
--disable-nls \
--with-gmp=$GMPDIR \
--with-mpfr=$MPFRDIR
any tips? thank you
