I have just installed djgpp according to all the directions (it seems).

I have a certain module I cannot compile into an executable. It is called
IniUtils.cpp. Here's a brief rundown of it and it's .h file:

*IniUtils.h*
#ifndef __INI_UTILS__
#define __INI_UTILS__

// here's the class and prototypes for the methods.

#endif __INI_UTILS__

*IniUtils.cpp*
#include <fstream.h>
#include "StringUtils.h" // defined by me.
#include "IniUtils.h"

// class methods are defined here

int main() {
    // do some stuff
}

I use the following command to compile to an object file:

gcc -c -Wall IniUtils.cpp

with no errors.

Later, I use the following command to compile to an executable:

gxx -o IniUtils.exe IniUtils.o

(sometimes I use gxx -o IniUtils.exe IniUtils.cpp)

I get the following error:

d:/djgpp/lib/crt0.o(.data+0xc2):crt0.s: undefined reference to `main'
d:/djgpp/lib/libc.a(crt1.o)(.text+0x446):crt1.c: undefined reference to
`main'

My PATH and DJGPP environment variables are both pointing to the correct
places on the D: drive.

I can't figure out what the problem is. Please help.

Morpheus.
