from other dependencies. This ensures that binaries in Spack dependencies
are preferred over system binaries.
-
-^^^^^^
-OpenGL
-^^^^^^
-
-To use hardware-accelerated rendering from a system-supplied OpenGL driver,
-add something like the following to your ``packages`` configuration:
-
-.. code-block:: yaml
-
- packages:
- opengl:
- paths:
- opengl+glx@4.5: /usr
- buildable: False
- all:
- providers:
- gl: [opengl]
- glx: [opengl]
-
-For `EGL <https://www.khronos.org/egl>` support, or for certain modern drivers,
-OpenGL calls are dispatched dynamically at run time to the hardware graphics
-implementation. This dynamic dispatch is performed using `libglvnd
-<https://github.com/NVIDIA/libglvnd>`. In this mode, the graphics library
-(e.g.: opengl) must be built to work with libglvnd. Applications then link
-against libglvnd instead of the underlying implementation. Environment
-variables set at run time govern the process by which libglvnd loads the
-underlying implementation and dispatches calls to it. See `this
-<https://github.com/NVIDIA/libglvnd/issues/177#issuecomment-496562769>` comment
-for details on loading a specific GLX implementation and `this
-<https://github.com/NVIDIA/libglvnd/blob/master/src/EGL/icd_enumeration.md>`
-page for information about EGL ICD enumeration.
-
-This codependency between libglvnd and the underlying implementation is modeled
-in Spack with two packages for libglvnd: libglvnd, which provides libglvnd
-proper; and libglvnd-fe, a bundle package that depends on libglvnd and an
-implementation. Implementations that work through libglvnd are no longer
-providers for graphics virtual dependencies, like "gl" or "glx", but instead
-provide libglvnd versions of these dependencies ("libglvnd-be-gl",
-"libglvnd-be-glx", etc.). The libglvnd-fe package depends on these
-"libglvnd-be-..." virtual packages, which provide the actual implementation.
-It also depends on libglvnd, itself, and exposes its libraries to downstream
-applications. For correct operation, the Spack package for the underlying
-implementation has to set the runtime environment to ensure that it is loaded
-when an application linked against libglvnd runs. This last detail is
-important for users who want to set up an external OpenGL implementation that
-requires libglvnd to work. This setup requires modifying the ``modules``
-configuration so that modules generated for the external OpenGL implementation
-set the necessary environment variables.
-
-.. code-block:: yaml
-
- packages:
- opengl:
- paths:
- opengl@4.5+glx+egl+glvnd: /does/not/exist
- buildable: False
- variants:+glx+egl+glvnd
- libglvnd-fe:
- variants:+gl+glx+egl
- all:
- providers:
- glvnd-be-gl: [opengl]
- glvnd-be-glx: [opengl]
- glvnd-be-egl: [opengl]
- gl: [libglvnd-fe]
- glx: [libglvnd-fe]
- egl: [libglvnd-fe]
-
-.. code-block:: yaml

- modules:
- tcl:
- opengl@4.5+glx+glvnd:
- environment:
- set:
- __GLX_VENDOR_LIBRARY_NAME: nvidia
- opengl@4.5+egl+glvnd:
- environment:
- set:
- __EGL_VENDOR_LIBRARY_FILENAMES: /usr/share/glvnd/egl_vendor.d/10_nvidia.json
-
-One final detail about the above example is that it avoids setting the true
-root of the external OpenGL implementation, instead opting to set it to a path
-that is not expected to exist on the system. This is done for two reasons.
-First, Spack would add directories under this root to environment variables
-that would affect the process of building and installing other packages, such
-as ``PATH`` and ``PKG_CONFIG_PATH``. These additions may potentially prevent
-those packages from installing successfully, and this risk is especially great
-for paths that house many libraries and applications, like ``/usr``. Second,
-providing the true root of the external implementation in the ``packages``
-configuration is not necessary because libglvnd need only the environment
-variables set above in the ``modules`` configuration to determine what OpenGL
-implementation to dispatch calls to at run time.
