Building the shaders
This document describes how to regenerate the shaders used by Pathfinder. Unless you have modified files in this directory, regenerating the shaders is not necessary to use Pathfinder or do most kinds of development on it.
You will need glslangValidator and spirv-cross installed to execute the
Makefile from this directory. You can speed up the build by parallelizing the
build: make -j.
macOS
You can use Homebrew to install the dependencies:
brew install glslang spirv-cross
Windows
glslangValidator and spirv-cross are available by installing the
Vulkan SDK. You'll also need some commands
like make, rm, etc. These are available on the
Windows Subsystem for Linux
shell. You'll need to set these environment variables for make to succeed:
export GLSLANG=glslangValidator.exe
export SPIRVCROSS=spirv-cross.exe
Note: the Windows versions of glslangValidator and spirv-cross may change
the line endings of the generated output. Please take care to ensure that
unintended line ending changes aren't accidentally committed, for instance by
configuring Git to automatically handle line endings.
