+# OpenXR in NixOS

+OpenXR is a standard for eXtended Reality (XR) applications and drivers (providers).
+
+OpenXR runtime providers must ensure that the library path of the runtime's shared library can be loaded by Nix applications. If your OpenXR runtime provider runs in an FHSEnv, this means you may have to use `auto-patchelf` to link dependencies to the Nix store.

 #### How do I avoid compiling a GCC cross-compiler from source? {#cross-qa-avoid-compiling-gcc-cross-compiler}
-On less powerful machines, it can be inconvenient to cross-compile a package only to find out that GCC has to be compiled from source, which could take up to several hours. Nixpkgs maintains a limited [cross-related jobset on Hydra](https://hydra.nixos.org/jobset/nixpkgs/cross-trunk), which tests cross-compilation to various platforms from build platforms "x86\_64-darwin", "x86\_64-linux", and "aarch64-linux".  See `pkgs/top-level/release-cross.nix` for the full list of target platforms and packages.  For instance, the following invocation fetches the pre-built cross-compiled GCC for `armv6l-unknown-linux-gnueabihf` and builds GNU Hello from source.

 The *existence* of setups hooks has long been documented and packages inside Nixpkgs are free to use this mechanism. Other packages, however, should not rely on these mechanisms not changing between Nixpkgs versions. Because of the existing issues with this system, there’s little benefit from mandating it be stable for any period of time.
