How to link multiple files in Turbo C++? - c++

Question

I know Turbo C++ is oudated as hell, but so is the curriculum of our central board in my country (India). And I am doing a school project. And I don't have the freedom to choose my own IDE and compiler. Go figure.
NOTE: I am using Turbo C++ 3.0 in DOSBox in Win10
Anyway, here is the project directory I made to test TC++'s linking:
TC/BIN
-MAIN.CPP
#include <iostream.h>
#include <conio.h>
#include "CL.H"
int main()
{
clrscr();
cout<<"HW";
cl c;
c.set(5);
cout<<c.get();
getch();
return 0;
}
-CL.CPP
#include "CL.H"
void cl::set( int i )
{
a = i;
}
int cl::get()
{
return a;
}
-CL.H
#ifndef CL_H
#define CL_H
class cl
{
int a;
public:
void set( int i);
int get();
};
#endif
All of these compile fine. Upon trying to link, I get the following linker error:
LINKER ERROR: Undefined symbol cl::get() in module MAIN.CPP
LINKER ERROR: Undefined symbol cl::set( int ) in module MAIN.CPP

Answer 1

You can do that:
1- Open TC.exe
2- From project select Open Project
3- Enter the name of project eg: MyProj.prj and Press ok.
4- From project select Add item
5- Locate all the source files and add them.
6- compile and build.

I had the .h files also added to the project. That caused all the trouble. Removing the .h files from the project seems to make it work.
