    What on earth is 64bit programming?


    Hello,

    I think I dont know what is 64bit programming...if even exist.. . What is the difference between 32 and 64 bit application?

    Is the difference in data types only?

    There really isn't any difference at all, except for the low level aspects of things. The only thing to be concerned with is that 32-bit systems can't run 64-bit software, so a recompile is in order.

    thanks....

    So that means I will need 64bit compiler as well? Or I will be able to use same compiler just on 64bit system?

    I've only used GCC, and with that you only need one compiler. My default is 64bit, so to use 32bit I just use -m32....
