g++ 64 bit compile option?

successful install gcc64
but...

try this:

Please consider using one of the 32 headers found in section 17.4.1.2 of the C++ standard. Examples include substituting the header for the header for C++ includes, or instead of the deprecated header . To disable this warning use -Wno-deprecated.

do you know g++ 64 bit compile option?

[H.Merijn Brand (procura]

If your gcc/g++ is ELF 64, it can *only* produce 64bit code. You need a seperate gcc/c++ to produce 32bit code. There is no option (yet) to switch from 32 to 64 bit or back.

There /is/ an option to switch architecture, and it /does/ have effect: -mpa-risc-2-0 / -mpa-risc-1-1 (or something like that) check with 'gcc -v --help'
