Which package to install to get header file glad.h?

I am trying to compile this example https://learnopengl.com/Getting-started/Hello-Window:

#include <glad/glad.h>
#include <GLFW/glfw3.h>
// ...

I have installed libglfw3-dev but I am still missing the glad.h header file. A search on packages.ubuntu.com gave no results. There is a github page for glad but it does not provide glad.h as far as I can see.

Solution 1:

Thanks to @dc37 for the comment on the webservice! Here is what I did: Go to the webservice and download the required files:

Check the "local files" option and click on the "Generate" button in the lower right corner,

download the glad.zip file to the current directory and extract it.

Create a test program test.cpp:

#include <iostream>
#include "glad.h"
#include <GLFW/glfw3.h>  
void framebuffer_size_callback(GLFWwindow* window, int width, int height)
{
    glViewport(0, 0, width, height);
}

int main() {
    glfwInit();
    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
    glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
    //glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE);
    GLFWwindow* window = glfwCreateWindow(800, 600, "LearnOpenGL", NULL, NULL);
    if (window == NULL) {
            std::cout << "Failed to create GLFW window" << std::endl;
            glfwTerminate();
            return -1;
    }
    glfwMakeContextCurrent(window);
    if (!gladLoadGLLoader((GLADloadproc)glfwGetProcAddress)) {
        std::cout << "Failed to initialize GLAD" << std::endl;
        return -1;
    }
    glViewport(0, 0, 800, 600);
    glfwSetFramebufferSizeCallback(window, framebuffer_size_callback);
    while(!glfwWindowShouldClose(window)) {
        glfwSwapBuffers(window);
        glfwPollEvents();    
    }
    glfwTerminate();
    return 0;
}

Compile it (remember to install libglfw3-dev first):

g++ -c glad.c 
g++ test.cpp -o my_test glad.o -lglfw -ldl

Run it:

$ ./my_test

(It shows an empty window on the screen)
