For example, to link DJGPP and NASM you need:
Set up DJGPP:set djgpp=c:\djgpp\DJGPP.ENVset path=%path%;c:\djgpp\bin
A C file:
#include <stdio.h>
int main(void)
{
return 0;
}
An ASM file:bits 32
;Things from NASM are declared global:
;;
global _call0
;Things from DJGPP are declared extern:
;;
extern _printf
_call0:
ret
A BAT file for building:nasm asm.asm -f coff -o asm.o
gcc asm.o c.c -o exe.exe

Hello,
I’m currently trying to make a function in a separate assembly file, but I’m
having problems linking it with a C program. Are there any guides that show how
to do this?
Thanks in advance,
-Knedlik
