Commands to compile run and clean the output file

make compiles the source code and runs the executable. make clean cleans up the compiled file.

OpenGL Setup Guide for Arch Linux

This guide will take you through the steps to set up a new OpenGL project on Arch Linux using GLFW for window management and input, and GLAD for OpenGL function loading.

Update Your System

Ensure that your system's package list and installed packages are up-to-date:

sudo pacman -Syu

Install Development Tools

Install the base-devel group of packages which includes the gcc compiler, make, and other development tools:

sudo pacman -S base-devel

Install OpenGL Libraries

Mesa is the open-source implementation of OpenGL. Install it with:

sudo pacman -S mesa

Install GLFW

GLFW is a library that allows the creation of windows with an OpenGL context and manages input. Install it with:

sudo pacman -S glfw

Generate and Install GLAD

GLAD is used to load OpenGL functions. Generate the GLAD loader for your OpenGL version using the Glad web service (https://glad.dav1d.de/), then download and include the files in your project.

Setup Your Project Structure

Create a new directory for your project with the following structure:

project_name/
│
├── include/
│   ├── glad/
│   │   └── glad.h
│   └── KHR/
│       └── khrplatform.h
│
├── src/
│   └── glad.c
│
├── main.cpp
└── Makefile

Write Your Makefile

Create a Makefile in your project root that compiles your source code:

CC=g++
CFLAGS=-Iinclude
LDFLAGS=-ldl -lglfw
TARGET=learning-opengl

all:
    $(CC) main.cpp src/glad.c $(CFLAGS) $(LDFLAGS) -o $(TARGET)
    ./$(TARGET)

clean:
    rm -f $(TARGET)

Remember to replace placeholder values such as project_name and learning-opengl with your actual project name and desired executable name. The CC, CFLAGS, LDFLAGS, and TARGET variables are set for compiling and linking, and should be adjusted if your setup differs.
