spirv-to-dxil-rs

Safe Rust bindings to spirv-to-dxil.

Building

spirv-to-dxil-rs builds a copy of spirv-to-dxil statically from Mesa.

• A compatible C and C++ compiler

  • MSVC 2019 16.11 or later is required to build on Windows.

A script to clone a minimal subset of Mesa required to build spirv-to-dxil has been provided.

$ ./clone-mesa.sh
$ cargo build

Updating Mesa

Unless you are maintaining spirv-to-dxil-rs, you do not need to update Mesa frequently.

Updating Mesa requires Python 3.6 and mako to pre-generate templated files. CMake is also required to regenerate the Rust bindings from spirv-to-dxil.h, this is to ensure that bindings can be generated regardless of whether changes need to be made to the spirv-to-dxil-sys build script.

1. Update the submodule to HEAD

   git submodule update --init --remote --depth 1 --single-branch --progress spirv-to-dxil-sys/native/mesa

2. Re-apply sparse-checkout

   git submodule absorbgitdirs
   git -C spirv-to-dxil-sys/native/mesa config core.sparseCheckout true
   git -C spirv-to-dxil-sys/native/mesa config core.symlinks false
   cp spirv-to-dxil-sys/native/mesa-sparse-checkout .git/modules/spirv-to-dxil-sys/native/mesa/info/sparse-checkout
   git submodule foreach git sparse-checkout reapply
   

3. Regenerate bindings

   cargo run --bin bindings_generator
   

4. Regenerate mako-generated files for cc

   ./mesa_mako
