X11 Hello World!

X11 windowing system and GLX based C++ application with basic colored triangle following the mouse position, which is rendered with modern OpenGL graphics.

Technologies

• X11 library for native OS windowing and input handling
• GLX for OS specific OpenGL context setup
• OpenGL for graphics
• C++ language (11 standard)
• CMake for build configuration

Dependencies

• glm for 3d vector math and transformations
• glew for OpenGL functions and extensions loading

These dependencies are stored as project submodules. No extra installation step is required.

Platforms

• Linux-based OS with X11 and GLX support

Get started

Requirements

• Linux-based OS (tested on Ubuntu 20.04)
• GCC compiler for C++11 (tested on 8.4.0)
• CMake 3.11 or greater (tested on 3.16.3)

Configuration

To build requires X11 and OpenGL packages, as well as GLEW's dependencies to be installed. So, the set of required tools can be installed as follows (may be too excessive):

$ sudo apt-get update -y
$ sudo apt-get install -y libgl1-mesa-dri libgl1-mesa-glx libgl1-mesa-dev
$ sudo apt-get install -y libxmu-dev libxi-dev libgl-dev libglx-dev
$ sudo apt-get install -y libx11-dev
$ sudo apt-get install -y xorg-dev

Get the source code

$ git clone https://github.com/EgorOrachyov/X11HelloWorld.git
$ cd X11HelloWorld
$ git submodule update --init --recursive

Configure and build

$ mkdir build
$ cd build
$ cmake ..
$ cmake --build .

Run application

./x11helloworld
