With this PR, a user can designate older versions of OpenGL as an
external Spack package, and dependents can use that installation
as long as they do not have version requirements.
MacOS currently comes with OpenGL 2.1; there is currently no
'provides' directive in the OpenGL Spack package which specifies a
gl version provided for versions earlier than OpenGL 3.3, so earlier
versions of OpenGL are not considered to provide any version of gl.
This PR records that any version of OpenGL provides 'gl' (which is
sufficient for any package that does not require a specific version
of gl).
* mesa: re-writen to new meson build system
* xorg-server: Remove unneeded mesa dependency
* glx: provide the virtual GLX package
* Convert most "mesa" dependencies to use virtual gl and glx dependencies
* mesa: Switch to always building from the git repo instead of a tarball
* Use gl and glx version ranges instead of exact versions
* glx: provide a default package
* add auto to swr variant
* Revert "add auto to swr variant"
This reverts commit 2e7cd8a8ac.
* update mesa package to version 19.0
* set +glx by default only when running on linux
* fix style issues in geant4 package
* remove virtual package "egl"
- remove the old LGPL license headers from all files in Spack
- add SPDX headers to all files
- core and most packages are (Apache-2.0 OR MIT)
- a very small number of remaining packages are LGPL-2.1-only
* glvis@3.3: new package
* mesa-glu: now provides 'glu' (GL Utility library)
* openglu: add package, provides glu
* [GLVis] Use MakefilePackage as base. Add 'develop' version.
Small tweaks in the makefile arguments.
* [GLVis] Locate the X11, GL and GLU libraries within their respective
prefixes. Set the C compiler in the makefile arguments.
* [GLVis] Fix a bug: the same variable was used for two different things.
* [libx11] Add the libs property
* [OpenGL] Add the libs property
* [OpenGLU] Add the libs property
* [GLVis] Use the libs properties of libx11, opengl, and openglu
* opengl: make error throw on install, not fetch
* opengl: add configuration advice for darwin
* opengl: add more versions of GL/OpenGL
* opengl: improve documentation in comments
* [OpenGL] Fix formatting
This provides options for hardware and software rendering with the
gl API and updates the vtk package to make use of those options:
* Create new "gl" virtual package, provided by mesa
* Add external-only "opengl" package, which represents a system
install that provides gl
* For vtk: prefer system gl implementation by default to get speed
up from hardware rendering. When software rendering is specifically
requested (+osmesa), try to use the llvmpipe approach, as it is
much faster.
* Make qt dependency optional for vtk
* Add basic support for VTK on osx
* qt: Depend on virtual gl package, rather than mesa impl
