GLFW initialized, yet not?

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

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
