It's impossible to say without more information (e.g. exact errors
messages).

The main issue is that everything has to use the same architecture:
you can't link a 32-bit executable against 64-bit libraries or vice
versa.

That option only affects certain platforms, specifically AIX, HP-UX,
IRIX and Solaris.

On Linux, unless there's something wrong with your build environment,
you shouldn't need any additional options. The compiler should
automatically generate 64-bit object files and the default library
search paths used by the linker should only contain 64-bit libraries.

If you need to use any libraries which you compiled yourself, ensure
that they were built as 64-bit. Don't point any --with-*-includes=
options to directories containing 32-bit libraries.
