I’m having this weird issue where the glfwCreateWindow function fails, complaining about how I havn’t initialized GLFW, even though the glfwInit function returns successful just before?

I’m guessing the reason for this might be because I havn’t setup GLFW completely correctly, but if so I’m gonna need some help getting that fixed, as I’m not to experienced in setting up external libraries, especially in Code::Blocks.

Here’s is an outtake from my Base class’s Init function, which is where I’m getting the error

```auto
bool Base::Init()
{
    glfwSetErrorCallback( error_callback );
    
    if( !glfwInit() ) // <-- this function returns true, yet sends an error to the error_callback function
    {
        cout << "Failed to initialize GLFW!" << endl;
        return false;
    }
    
    // Here is my main issue. GLFW sends the same error to the call_back function again
    window = glfwCreateWindow( 800, 600, "GLFW Window", glfwGetPrimaryMonitor(), NULL )
    
    if( !window )
    {
        cout << "Failed to create window!" << endl;
        return false;
    }
    
    glfwMakeContextCurrent( window );
    
    ...
    
    return true;
}

```

Here’s the error messages from the console

> 65537 The GLFW library is not initialized  
> 65537 The GLFW library is not initialized  
> Failed to create window!

Thanks in advance for any help you can give me

Have you tried placing the glfwSetErrorCallback( error\_callback ); after the glfwInit();?

According to the documentation the glfwSetErrorCallback is one of the functions that may be called before glfwInit. Initially I didn’t have that function at all, and added it after the window failed to create.

I can try to do what you say, but I doubt it’ll change anything

edit:  
I tried changing the order, but got the same result  
Interesting enough, I still got 2 of the 65537 error - I thought one of them came from glfwInit, but apparently not

In any case, thanks fro your reply
