A cross-platform C++ binding for OpenGL that provides type-safe parameters, lazy function resolution, and multi-context support.
glbinding is a cross-platform C++ binding for the OpenGL API, generated from the official Khronos gl.xml specification. It provides a type-safe, modern alternative to traditional C bindings by leveraging C++11 features like enum classes and variadic templates, eliminating the need for macros and improving code safety.
C++ developers working with OpenGL for graphics applications, including those building games, visualization tools, or scientific simulations who need a robust, type-safe interface to the OpenGL API.
Developers choose glbinding for its compile-time type safety, per-feature API headers that enforce version compliance, and advanced features like multi-context support and function callbacks, which reduce runtime errors and improve debugging compared to alternatives like GLEW.

Enforces strict parameter checks at compile time, preventing errors like passing enums where bitfields are expected, as demonstrated in the type-safe parameters section.
Provides per-OpenGL-version headers (e.g., gl32core) to ensure code adheres to specific API subsets, reducing runtime errors from using unsupported functions.
Supports global and per-function callbacks for tracing, logging, and error checking, enabling seamless integration of debugging tools without modifying core code.
Built-in management for multiple OpenGL contexts across threads, with explicit context switching APIs, facilitating complex graphics applications as shown in the multi-context examples.
Dependency on KHR/khrplatform.h headers can be cumbersome, requiring system-wide installation or internal copies, complicating cross-platform builds and project setup.
Requires CMake 3.0+ and C++11 compliant compilers, with optional dependencies for examples, which can be a barrier for projects with outdated or minimal toolchains.
As admitted in the README, enum groups are incomplete and unmaintained, so compile-time checks for enums (e.g., glCreateShader parameters) are limited, leaving room for runtime errors.
