I'm currently trying to make a program that should run in VGA-mode. To do this I'm trying to use assembly. My basic assembly code looks like this: mov ax, 0013h int 10h But since Dev-C++ uses the AT&T syntax I think it should look like this: mov H0013, %ax int H10 But when I try to compile this I get an error from the assembler telling me that: "suffix or operands invalid for 'int' I have found no reason to why this is happening. Does anyone have a solution?

Inline assembly for x86 in Linux

(Don't be fooled by the title)

BTW, GCC has an option like -masm=intel, so you can use the intel assembler syntax...

What you're trying to do won't work anyway. You can generate interrupts like that in programs that run in a 16-bit OS like DOS, not in 32-bit OS like Windows and in protected mode. You're probable going to get a fault when you'll try to execute the 'int' instruction. And no, console programs made in Dev-C++ are not DOS programs, they're still 32-bit Windows programs that just use a console.
