README

The repo contains simple demos of using GLFW, Glad and OpenGL.

Tested only with Linux Fedora 41, X11, glfw 3.5.0, glad 2.0.8 and zig 0.14.0

📌 Requirement

Before running the demos:

• check GLFW 3.5.0 requirements, especially installing dependencies; system environment is not checked for required packages and their absence may generate errors
• update Glad with webservice, existing files may not meet desired requirements (optional, check first include/glad/gl.h)
• install Zig 0.14.0 programming language
• install Clang (19.1.7), this version is informative, the code may or may not work with other versions

Demos requires linking to the C libraries from target environment; this is done by default, but the system must provide these libraries.

📌 Implementation

Repo uses the Zig Build System to build and run the demos written in C language.

GLFW and Glad are built by default when building a demo, and outputs will be in zig-out/include and zig-out/lib folders; see the related files in pkg/glfw and pkg/glad for their implementation.

More information are in build.zig and each demo file.

📌 Usage

Use zig build run -- demo/<folder_name> step to run a demo, output will be in zig-out/bin. Step zig build run uses the src folder by default.
