Basic OpenGL project template for c++ with CMake, glfw and gl3w meant to work out of the box on Windows and Linux

OpenGL_template

DISCLAIMER: This project is work in progress and thus breaking changes may appear without any previou announcement.

Basic OpenGL project template for c++ with CMake, glfw and gl3w meant to work out of the box on Windows (currently considered untested due to recent major changes) and Linux and eliminate as much frustration as possible in the setup phase of any OpenGL project or OpenGL prototype. It includes glfw.

It also features my OpenGL C-style C++11 wrapper library for a less verbose API for OpenGL along with gl3w as the OpenGL function loader. More details.

You can find examples of how to use this API in the examples folder.

Cloning

You should clone the repository with git clone --recursive https://github.com/Kravantokh/OpenGL_GLEW_GLFW_template/\

Current code

The file src/main.cpp contains a basic example code which creates an openGL context and opens it in a window with the help of glfw.

Prerequisites (for using the included compile.sh)

• CMake
• GNU GCC (mingw on Windows)
• ninja
• glu*
• Python (3 or 2 should both work)

*Linux-only dependency - may be installed with the package manager. On Arch the package glu exists on its own. On Debian the package containing it is libglu1-mesa-dev. On other distros it may be contained in a different package.

Build process

• Linux: run build.sh

On linux don't forget to run chmod +x build.sh.

Until now the build process has been succesfully tested on Arch Linux, Kubuntu 20.10 and Windows 10(before the major changes) with the mentioned build tools.

Errors you may meet

XInput headers not found; install libxi development package - Installing the package xorg-dev may help on Debian distros.

opengl_template's Issues

nonesense error at shader compilation

Sometimes the error handler does not properly print some errors in shader compilation.

Uniform location: 1Error during shader compilation: 0(60) : error C0000: syntax error, unexpected $undefined at token "<undefined>"

requires latest CMake version for apparently no good reason

Be honest, do you absolutely need CMake version 3.22.2 ?
