Hello. I can’t compile a simple program.

#include <GLFW/glfw3.h>

void render();

int main(int argc, char **argv)
{
    GLFWwindow* window;
    glfwInit();
    window=glfwCreateWindow(640, 480, "Test", NULL, NULL);
    glfwMakeContextCurrent(window);
    
    while(!glfwWindowShouldClose(window))
    {
        render();
        glfwSwapBuffers(window);
        glfwPollEvents();
    }
    
    glfwTerminate();
    return 0;
}

void render()
{
    glClear(GL_COLOR_BUFFER_BIT);
    
    glBegin(GL_TRIANGLES);
    glColor3f(0.0f, 1.0f, 0.0f);
    glVertex2f(-1.0f, 0.0f);
    glVertex2f(0.0f, 1.0f);
    glVertex2f(1.0f, 0.0f);
    glEnd();
}

Sorry for the horrible formatting, I don’t know why the text has turned a large size and has been cropped.

You are using an old version of MinGW. You need to manually link against gdi32.
