I tried to create a window with the simplest code possible:
#include <stdio.h>
#include <stdlib.h>
#include <GL/glew.h> // Always include it before glfw.h
#include <GLFW/glfw3.h>
#include <glm/glm.hpp>
int main(void) {
glfwInit();
glfwWindowHint(GLFW_VERSION_MAJOR, 3); // OpenGL 3.3
glfwWindowHint(GLFW_VERSION_MINOR, 3);
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GLFW_TRUE); // Mac
GLFWwindow* window = glfwCreateWindow(720, 480, "OpenGL", NULL, NULL); // Create a window
if (window == NULL) {
fprintf(stderr, "Failed to create window\n");
glfwTerminate();
return -1;
}
glfwMakeContextCurrent(window);
return 0;
}
This is my Makefile:
game:
g++ src/main.cpp -std=c++17 -o play -I include -L lib -l glfw.3 -l GLEW.2.2
When I compile my code there is no error, but when I try to play my code I have this error:
Failed to create window
Invalid window hint 0x00000003
Invalid window hint 0x00000003
Context profiles are only defined for OpenGL version 3.2 and above
Can someone help me? I don't know why my window doesn't want to be created...
GLFW_VERSION_MAJOR
& GLFW_VERSION_MINOR
are not valid arguments to glfwWindowHint
:
glfwWindowHint(GLFW_VERSION_MAJOR, 3); // OpenGL 3.3
^^^^^^^^^^^^^^^^^^ nope
glfwWindowHint(GLFW_VERSION_MINOR, 3);
^^^^^^^^^^^^^^^^^^ also nope
Use GLFW_CONTEXT_VERSION_MAJOR
& GLFW_CONTEXT_VERSION_MINOR
instead.
As per the docs, emphasis mine:
GLFW_CONTEXT_VERSION_MAJOR
andGLFW_CONTEXT_VERSION_MINOR
specify the client API version that the created context must be compatible with. The exact behavior of these hints depend on the requested client API.Note: Do not confuse these hints with
GLFW_VERSION_MAJOR
andGLFW_VERSION_MINOR
, which provide the API version of the GLFW header.
