undefined reference error

May 21st, 2008

Hi I am getting an undefined reference error from my code
here is a snippet of my code.

 Help with Code Tags 
 C Syntax (Toggle Plain Text) 
#include <stdio.h>
#include <windows.h>
 
//defining functions
void ErrorFunc(int error);
 
int error = 0;
 
int main(void){
    return 0;
}
 
void ErrorFunc(int error)
{
    FunctionFromALibrary(error);
}
#include <stdio.h>
#include <windows.h>

//defining functions
void ErrorFunc(int error);

int error = 0;

int main(void){
    return 0;
}

void ErrorFunc(int error)
{
    FunctionFromALibrary(error);
}

I am using DEVC++ 5 and I have included the library that I need to use in the project-project options-parameters - linker
there i have:

thisLibrary.lib
-lmingw32

I also added that directory in
project-project options-directory-directories-library directories

it is at least partially linked because if i hold my mouse of the
FunctionFromALibrary()
DEVC++ will show me the prototype

thisLibrary.lib
-lmingw32

You need to check the naming convention, and whether (or not) you need the initial -l
For example, saying mingw32 could really mean libmingw32.lib

Any libraries of your own would need to follow the same naming convention.
