# TODO(baryluk): Standard depencies required: cmake, ninja, repo, git, gcc/g++, wayland-client, libxcb, libxml2, python3, perl, llvm
# Optional: valgrind, go, ocaml.

# I think the llvm actually doesn't need to be installed, because it is a part of downloaded and patched repo.

Note: This script is a bit outdated. You will need to compile DirectXShaderCompiler first (64-bit is enough, we only need dxc tool during compilation to convert some ray tracing shaders).

Make sure to use version of DXC that is supported (check amdvlk README which version is supported, as newer versions might not work, or throw errors with amdvlk current rt pipelines code - this will be fixed eventually). If you use newer compiler like gcc 13.x, you might need to do a bit of patching (modifying Version.h to have #include <cstdint>), and pass few extra options to cmake to gcc to not emit errors/warnings in few places. Then it builds on modern gcc.

After that, install dxc, or make it available in your PATH. amdvlk should then build without issues. You might adjust the sed slightly, as some paths to json icd files changed.
