how to use GLFW with openGL? - c++

Question

I'm trying to compile a short openGl and GLFW code but I'm failing in..
I've included all the .h like this :
#include <stdio.h>
#include <stdlib.h>
#include <GL/glew.h>
#include <GL/glfw2.h>
I'm on linux so I've made a :
sudo zypper install libglfw2
When I'm compiling like this :
g++ main.cpp -lGLU
I have :
main.cpp:14:22: fatal error: GL/glfw2.h:Any file or directory
#include <GL/glfw2.h>
^
compilation terminated.
I've also tried to include #include <GL/glfw3.h> but without success.
This is my complet code :
#include <stdio.h>
#include <stdlib.h>
#include <GL/glew.h>
#include <GL/glfw2.h>
int main()
{
if (glfwInit() == false)
{
fprintf(stderr, "GLFW failed to initialise.\n");
return (-1);
}
glfwWindowHint(GLFW_FSAA_SAMPLES, 4);
glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
GLFWwindow* window;
window = glfwCreateWindow(640, 480, "OPENGL", NULL, NULL);
if (!window)
{
fprintf(stderr, "Window failed to create\n");
glfwTerminate();
return (-1);
}
glfwMakeContextCurrent(window);
glewExperimental = true;
if (glewInit() != GLEW_OK)
{
fprintf(stderr, "Failed to initialize GLEW\n");
return (-1);
}
return (0);
}
Could someone know what I have to do to compile my code ?
Thanks

There is no GL/glfw2.h and never has been, and the code above uses the GLFW 3 API. See Renamed library and header file for more information about header paths.
There is no reason to use GLFW 2 for new projects, so I would avoid the libglfw2 package. Instead see if there is a GLFW 3 package.
