I am using glfw and glew to create the window and it's giving me linker errors. How can I fix it. This is my first time installing glfw and glew so I could've missed a step in the installation. Any help?
I compile my code using just:
gcc main.c
I know there are some linker flags, but glfw and glew are not a part of them.
I use linux with the gcc compiler.
This is my code:
#define GLEW_STATIC
#include <stdio.h>
#include <stdlib.h>
#include <GL/glew.h>
#include <GL/glfw3.h>
#include <stdbool.h>
int main(){
glewExperimental = true;
if(!glfwInit()){
printf("failed to initialize GLFW\n");
return -1;
}
glfwWindowHint(GLFW_SAMPLES, 4);
glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE);
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
GLFWwindow* window;
window = glfwCreateWindow(1024, 768, "Game", NULL, NULL);
if(window == NULL){
printf("Sorry to say this, but your OpenGL version must be 3.3 or above! Thanks for playing, but to continue you must update your video card drivers or if you use an old GPU you may have to replace it with a new one to play this game. I will be developing my game for OpenGL 1 and 2 soon so stay on touch.");
glfwTerminate();
return -1;
}
glfwMakeContentCurrent(window);
glewExperimental = true;
if(glewInit() != GLEW_OK){
printf("Failed to initilize GLEW");
return -1;
}
}
This is the error log:
