  "github_readme_excerpt": "![Ubuntu](https://github.com/anholt/libepoxy/workflows/Ubuntu/badge.svg)\n![macOS](https://github.com/anholt/libepoxy/workflows/macOS/badge.svg)\n![MSVC Build](https://github.com/anholt/libepoxy/workflows/MSVC%20Build/badge.svg)\n![MSYS2 Build](https://github.com/anholt/libepoxy/workflows/MSYS2%20Build/badge.svg)\n[![License: MIT](https://img.shields.io/badge/license-MIT-brightgreen.svg)](https://opensource.org/licenses/MIT)\n\nEpoxy is a library for handling OpenGL function pointer management for\nyou.\n\nIt hides the complexity of `dlopen()`, `dlsym()`, `glXGetProcAddress()`,\n`eglGetProcAddress()`, etc. from the app developer, with very little\nknowledge needed on their part.  They get to read GL specs and write\ncode using undecorated function names like `glCompileShader()`.\n\nDon\u0027t forget to check for your extensions or versions being present\nbefore you use them, just like before!  We\u0027ll tell you what you forgot\nto check for instead of just segfaulting, though.\n\nFeatures\n--------\n\n  * Automatically initializes as new GL functions are used.\n  * GL 4.6 core and compatibility context support.\n  * GLES 1/2/3 context support.\n  * Knows about function aliases so (e.g.) `glBufferData()` can be\n    used with `GL_ARB_vertex_buffer_object` implementations, along\n    with GL 1.5+ implementations.\n  * EGL, GLX, and WGL support.\n  * Can be mixed with non-epoxy GL usage.\n\nBuilding\n--------\n\n```sh\nmkdir _build \u0026\u0026 cd _build\nmeson\nninja\nsudo ninja install\n```\n\nDependencies for Debian:\n\n  * meson\n  * libegl1-mesa-dev\n\nDependencies for macOS (using MacPorts): \n\n  * pkgconfig\n  * meson\n\nThe test suite has additional dependencies depending on the platform.\n(X11, EGL, a running X Server).\n\nSwitching your code to using epoxy\n----------------------------------\n\nIt should be as easy as replacing:\n\n```cpp\n#include \u003cGL/gl.h\u003e\n#include \u003cGL/glx.h\u003e\n#include \u003cGL/glext.h\u003e\n```\n\nwith:\n\n```cpp\n#include \u003cepoxy/gl.h\u003e\n#include \u003cepoxy/glx.h\u003e\n```\n\nAs long as epoxy\u0027s headers appear first, you should be ready to go.",

  "why_use_this": "Epoxy eliminates the tedious boilerplate of manually loading OpenGL functions via dlopen/dlsym/glXGetProcAddress, automatically resolving function pointers at first use. Essential as a build dependency for OpenGL applications that need to support multiple GL versions and contexts (core, compatibility, GLES) without platform-specific code. Widely used in graphics tooling and 3D apps."
