Code::Blocks - how to compile multiple source files

Question

I'm trying to compile a program with multiple source files - two CPP files and a header file, with code::blocks. As an example, I have created the following three files (an example program created by someone else on another forum):

main.cpp:

#include <stdio.h>
#include "other.h"

int main (void)
{
    printf("%d\n", getfavoritenumber());

    return 0;
}

other.cpp

#include "other.h"

int getfavoritenumber(void)
{
    return 3;
}

other.h

#ifndef _OTHER_H_
#define _OTHER_H_

int getfavoritenumber(void);

#endif

Despite the fact that these three files should link to each other, I receive the error "Linking stage skipped (build target has no object files to link)" when I try to build the project.

What am I doing wrong? Trying to compile the individual files presents the error "That file isn't assigned to any target".

Answer 1

Here is what worked for me:

Go to the left panel that says projects, and right-click on .cpp file. Select properties, then go to build. Check the boxes under the heading Belongs in Targets: "Debug" and "Release"

Answer 2

I had a similar problem when creating my first multi source code project. i believe the problem you are having is not with the linking but with you #include statement for me the directory's were different to what i expected. to include the header file in a project i had to write #include "include/other.h" have a look at how your folder system is constructed....if you could post what folders/directory`s you have in the project i might be able to give you a better answer.
