Unable to compile a C++ class using code blocks

Question

Everytime I try to compile a class in c++ I get this error:

||=== Build file: "no target" in "no project" (compiler: unknown) ===|

Here is the code for my Classes class:

#include <iostream>
#include "Cat.h"
using namespace std;

int main() {
    Cat cat1;
    cat1.speak();
    cat1.jump();

    return 0;
}

Here is the code for my header Cat.h:

#ifndef CAT_H_
#define CAT_H_

class Cat {
public:
    void speak();
    void jump();
};

#endif /* CAT_H_ */

And here is the code for my Cat Class:

#include <iostream>
#include "Cat.h"
using namespace std;

void Cat::speak() {
     cout << "Meouwww!!!" << endl;
}

void Cat::jump() {
    cout << "Jumping to top of bookcase" << endl;
}

You should learn a bit about the IDE you're using, or run some tutorial. — A.S.H

This error have nothing to do with your code. It's a problem related to your environnement. There is 2 commun mistake that will lead to this:

There is no compiler associated with your IDE so try to install one. Or you should Download codeBlocks with mingw compiler integrated

You didn't create a project So try creating a project and then add this files.

I hope that I answered your question.

I created the project , then I added all of the files to the folder of the project and I am still getting the same error when I attempt to compile it. So complicated

Am I required to install mingw in order for a class file to compile?

I did not install mingw when I initially installed codeblocks
