Also adds some additional asserts for version matching to these packages
continuation of #109595
pkgconfig was aliased in 2018, however, it remained in
all-packages.nix due to its wide usage. This cleans
up the remaining references to pkgs.pkgsconfig and
moves the entry to aliases.nix.
python3Packages.pkgconfig remained unchanged because
it's the canonical name of the upstream package
on pypi.
For APIs that use driver config files, the config files should point to libraries using absolute paths, so `RUNPATH` should be unnecessary. It is still needed for `libGLX` because that does not use config files but the dispatch library receives just a vendor name from the X server.
Even though FALLBACK_DATA_DIRS is set to include this, it only applies when XDG_DATA_DIRS is not defined, so the NixOS opengl.nix module still had to include these in the search path. Use a simple patch to force a default search path, consulted after all other search paths.
Note that FALLBACK_DATA_DIRS is no longer set, and the default (/usr/local/share:/usr/share) applies.
Previously we were relying on LD_LIBRARY_PATH to discover driver libraries (libGL, ligGLX, libEGL, OpenCL and Vulkan). This has the problem that setuid programs (in particular VirtualBox) ignore LD_LIBRARY_PATH. Fix it by setting RUNPATH in various dispatch libraries.
This is not needed for libvdpau because it is already configured to look for libraries in the driver paths.
Fixes https://github.com/NixOS/nixpkgs/issues/22760.
This makes the command ‘nix-env -qa -f. --arg config '{skipAliases =
true;}'’ work in Nixpkgs.
Misc...
- qtikz: use libsForQt5.callPackage
This ensures we get the right poppler.
- rewrites:
docbook5_xsl -> docbook_xsl_ns
docbook_xml_xslt -> docbook_xsl
diffpdf: fixup
When vulkan tries to load validation layers, it looks for JSON files in
several directories, one of which is:
<vulkan-loader>/etc/vulkan/explicit_layer.d
It does *not* look in:
<vulkan-loader>/share/vulkan/explicit_layer.d
Yet that is where the install phase of the vulkan-loader default.nix
places the files. Thus, I modified the install phase to place them in
the etc location instead.
* Implement libGL as a symlink package which uses libraries from libglvnd and
headers from Mesa (since ones from libglvnd are outdated).
* Use libGL_driver.driverLink treewide; add FHS paths where possible.
