Compiling a class with separate source and header - c++

Question

EDIT: the solution to the problem is the following: http://www.jusuchyne.com/codingchyne/2011/03/codeblocks-failed-to-find-the-header-file/
It won't compile, I have the following errors:
foo.h no such file in directory;
foo has not been declared;
num was not declared in this scope
foo is not a class or a namespace
It is odd, to say the least, because I just used the code blocks "Create a new Class" and then added it to this project. This is the source code:
Header:
#ifndef FOO_H
#define FOO_H
class foo
{
private:
int num;
public:
foo();
void set_num(int set);
int get_num();
};
#endif // FOO_H
the cpp
#include "foo.h"
foo::foo()
{
num = 10;
}
void foo :: set_num(int set)
{
num = set;
}
int foo :: get_num()
{
return num;
}
Disregard the calss itself and what it does, the problem is that it doesn't compile even though I used the default code blocks class creation setting.
The errors:

Answer 1

If the header is not in the same directory you must either specify the path in the include command, or you must add -I Path directive to your makefile or include settings.
Maybe this link also helps as codeblock seems to have problems.

This should be a comment, but I don't have 50 rep yet...
Can you navigate to the source directory in the command line and try to compile manually to ensure that the error isn't with the IDE?
If your IDE is using g++ (it probably is) then the command would be g++ foo.cpp

Answer 3

Open Windows Explorer
Navigate to the folder containing the files
Make sure the header is called "foo.h" (You know Explorer sometimes hides file extensions, right?)
If that doesn't do it, your compiler is broken.
