Introduction

Eselect (OpenGL) (also called eselect-opengl) is a module for Eselect that allows the OpenGL implementation on a Funtoo Linux or Gentoo Linux system to be switched between a variety of installed OpenGL implementations. It functions by creating an env,d file at /etc/env.d/03opengl which contains OpenGL settings. A sample env.d file for a multilib system with xorg-x11 OpenGL implementation may look like this:

/etc/env.d/03opengl - An example env.d file for eselect-opengl
# Configuration file for eselect
# This file has been automatically generated.
LDPATH="/usr/lib32/opengl/xorg-x11/lib:/usr/lib64/opengl/xorg-x11/lib"
OPENGL_PROFILE="xorg-x11"

Implementation

Eselect-opengl is implemented as a single bash-based Eselect module approximately 10K in size, installed at /usr/share/eselect/modules/opengl.eselect. One interfaces with this module via the main eselect command:

# eselect opengl help
Manage the OpenGL implementation used by your system
Usage: eselect opengl <action> <options>

Standard actions:
  help                      Display help text
  usage                     Display usage information
  version                   Display version information

Extra actions:
  list                      List the available OpenGL implementations.
  set <target>              Select the OpenGL implementation.
    <target>                  The profile to activate
    --use-old                 If an implementation is already set, use that one instead
    --prefix=<val>            Set the source prefix (default: /usr)
    --dst-prefix=<val>        Set the destination prefix (default: /usr)
    --ignore-missing          Ignore missing files when setting a new implementation
  show                      Print the current OpenGL implementation.


What is Switched

Eselect-opengl handles switching of the active:

  • Libraries (32-bit and 64-bit):
    • libGL
    • libEGL
    • libGLESv1
    • libGLESv2
  • C Headers:
    • /usr/include/GL/*
    • /usr/include/EGL/*
    • /usr/include/KHR/*
