g++ problem!!!

[milicic.marko]

I have very simple problem to solve.

I have three files

--
first is: main.cpp
--
#include "osoba.h"

int main (void)
{
osoba o;
o.stampaj();
}



--
Second is "osoba.cpp"
--
#include "osoba.h"

void
osoba::stampaj()
{
std::cout<<"zdravo";
}

osoba:soba()
{
}

osoba::~osoba()
{
}

--
Third is: "osoba.h"
--
#ifndef OSOBA_H
#define OSOBA_H

#include <string>

class osoba
{

public:

osoba();
~osoba();
void stampaj();

private:

std::string _ime;
std::string _nadimak;

};
#endif


When I complile, I got this error:
bash-2.05b$ g++ -o main main.cpp
/tmp/ccLgxIrl.o(.text+0x19): In function `main':
: undefined reference to `osoba:soba[in-charge]()'

How should I solve this problem?

I have very simple problem to solve.

I have three files

OK. You have two source files and you only compile one of them.

How should I solve this problem?

Add the second source file to your command line.

When I complile, I got this error:

bash-2.05b$ g++ -o main main.cpp

You have main.cpp and osoba.cpp but you only compiled main.cpp. Try

g++ -o main main.cpp osoba.cpp

I cannot see why, with the proper invocation, and
the required include of <iostream> (added below),
your code should not compile. Your invocation
did not include compilation and linking of osoba.cpp,
so the complaints you got are not surprising since
you (implicitly) asked for an executable image.

Here can be seen a CLI shell session:

Thanks you all.

It was all about compiling one instead of two files.

Silly me!

Ciao

 

[Larry Brasfield]

Thanks you all.

Not sure who is included here.

It was all about compiling one instead of two files.

Not *all*. As I mentioned, there was a problem
with your code that needed correction.

Silly me!

Yep, your silliness account has been debited.
Maybe somebody not in the red will care.
