    compiling assembly in linux with nasm

    So I started messing around with assembly but I am having some issues compiling.

    From the directions on one page I followed i did
    nasm -f elf program1.asm
    ls program1.o -o program1
    But then I got this error message
    ld: i386 architecture of input file `program1.o' is incompatible with i386:x86-64 output
    So I looked up the error and there wasnt a clear answer, but it seems the linker is trying to do 64 bit and nasm is doing 32bit? Am I on the right track?

    If your version of NASM is 2.00 or greater, try using "-f elf64" instead of "-f elf"
    	if (a) do { f( b); } while(1);
    	else   do { f(!b); } while(1);
