How do I add Gosu framework for XCode4 project?

Hey there,
I'm completely new to XCode and even tho I've been a programmer for 4 years, I have little to no knowledge about linking and referencing files/resources when it comes to compiled languages (I'm a Ruby programmer).

I'm trying my best using general tutorials on "how to add a framework to XCode 4 project", but I'm having a rough time trying to understand how am I supposed to do this, as everything I do fails in the end.

I've simply created a new cocoa application, went to build phases / Link Binary With Libraries and added Gosu.framework there. I didn't do anything else.

Now when I try to run the application, I get this error:

dyld: Library not loaded: @executable_path/../Frameworks/Gosu.framework/Versions/A/Gosu
  Referenced from: /Users/ellmo/Library/Developer/Xcode/DerivedData/gosuTest-hkmqdspnwjepredgslldpnmuhlvx/Build/Products/Debug/gosuTest.app/Contents/MacOS/gosuTest
  Reason: image not found

What should I do?

You also need to copy the framework into your app bundle. To do so, select your target, go to Build Phases and add a Copy File build phase. It needs to copy Gosu.framework into the "Frameworks" folder inside your app.

Hey, thanks, things moved on, but I have another problem.
I tried to follow https://github.com/jlnr/gosu/wiki/Getting-Started-on-OS-X so I deleted main.m and AppDelegates and such, and I added main.cpp wich contains the following code:


//
//  main.cpp
//  gosu test

#include "main.h"
#include <Gosu/Gosu.hpp>

class MyWindow : public Gosu::Window
{
public:
    MyWindow()
    :   Gosu::Window(640, 480, false)
    {
        setCaption(L"Hello World!");
    }
};

int main()
{
    MyWindow window;
    window.show();
}

Whenever I try to build, the compiler returns error for IO.hpp file

Lexical or Preprocessor Issue

Old versions of Gosu required the boost library. Please download the latest version here: http://libgosu.org/downloads/
