Hey guys, when I asssembled this AT&T macro file to .o and I disassembled it with objdump, it only shows the file format instead of the binary and source codes. What is wrong with the source codes here? Need to know it because it is urgent.

Urm, this is a fasm forum, you know that right?

But, however, I think the answer is clear. Defining macros will not generate any code. You have to use the macro in some way. Kind of like a recipe for meatloaf, the recipe itself is not edible, but if you get some real ingredients and follow the instructions within then you get a nice meal. Nice, that is, assuming that you are not a vegetarian.

Depends whether you write the recipe on rice paper or eggroll skins. But yeah Razz

To the OP, write an assembly stub and invoke your macro!

There is an updated version of these codes in MASM format, easier to convert, imho. Hm...over four years - seems OP solved his problem.

Haha sorry about that. I guess this forum hasn't had too much activity. I saw it in the first few posts and didn't look at the date.
