ASM and C

I am attempting to mix C++ and Assembly. I have the following code:

MIX.C

Code:

---

extern void sayhi(void);
extern void quit(void);

int CurrPos = (int)0xb8f9a;
char CurrChar = 'H';
//--------------------------------------------------------------------
int main(void)
        {
        sayhi();
        quit();
        }

---

MIX.ASM

Code:

---

GLOBAL _sayhi
GLOBAL _quit

extern _CurrPos
extern _CurrChar
SECTION .text

_sayhi:        mov byte [_CurrPos],'H'
        mov byte [0xb8f9e],_CurrChar
        ret

---

When I try to compile, i get the following error:
Error: COFF format does not support non-32-bit relocations.

This is for the line "mov byte [0xb8f9e],_CurrChar".

Will I have to declare CurrChar as an int so that its 32 Bits?

I'm not sure this will work but you could try:

Code:

---

asm { //this has to be in the same line
    GLOBAL _sayhi
    GLOBAL _quit //Your asm code

    extern _CurrPos
    extern _CurrChar
    SECTION .text

    _sayhi: mov byte [_CurrPos],'H'
        mov byte [0xb8f9e],_CurrChar
        ret
        }

---

Note that I've just copy-paste'd your code and don't know any assembly but this is how my book says you write asm in a C++ program.
Hope this helps

try adding:

Code:

---

[BITS 32]

to the top of the asm file. maybe it'll work, maybe not
