Hi,
I am trying to learn how to place classes in separate files.My main code is :
#include <iostream>
#include "Burrito.h"
using namespace std;

int main()
{
Burrito bo;

return 0;
}

My Burrito header file is :
#ifndef BURRITO_H
#define BURRITO_H


class Burrito
{
public:
Burrito();
protected:
private:
};

#endif // BURRITO_H

My Burrito Class is:

#include "Burrito.h"
#include <iostream>

using namespace std;
Burrito::Burrito()
{
cout<<"Tanmay Nath NBRC"<<endl;

}
I am using Ubuntu and I need to compile my main.cpp .I am using gcc main.cpp..Unfortunately it is giving me following errors:
/tmp/cc66TksP.o: In function `main':
main.cpp.text+0x10): undefined reference to `Burrito::Burrito()'
/tmp/cc66TksP.o: In function `__static_initialization_and_destruction_0(int, int)':
main.cpp.text+0x3e): undefined reference to `std::ios_base::Init::Init()'
main.cpp.text+0x43): undefined reference to `std::ios_base::Init::~Init()'
/tmp/cc66TksP.o.eh_frame+0x12): undefined reference to `__gxx_personality_v0'
collect2: ld returned 1 exit status


Please provide me the steps to compile it in correct manner.
Thanks

You need to compile this second file Burrito.cpp also, like that: Please use a CODE tags around your code for better readability.

Thanks it worked..I did not try g++, rather i was trying gcc main.cpp Burrito.cpp.This did not work.In brief can you explain why did gcc not work and g++ work?
Thanks

I believe because it is C++ you wrote and not C

thnx..

The gcc can compile C++ programs too (it detects it by .cpp file extension) but you also need a C++ library to link, which is done automatically by g++ and not by gcc.
