On Linux and macOS, the DirectX SDK is still required to compile shaders. On these platforms we use Wine to run the DirectX SDK tools.
To install Wine and winetricks on Linux, refer to your distribution's package database. Typically the package names will simply be wine and winetricks.
To install Wine and winetricks on macOS:
- Install Homebrew from https://brew.sh/
- Install wine with
brew cask install wine-stable - Install winetricks with
brew install winetricks - (If you already have these installed, update with:
brew update,brew upgrade wine-stable,brew upgrade winetricks)
Once Wine and winetricks are installed:
- Setup Wine with
winecfg - Install the DirectX SDK with
winetricks dxsdk_jun2010
Alternative method (works on Catalina): Instead of installing the DirectX SDK, you can place a copy of fxc.exe from the DirectX SDK in the build/tools directory. Then use env WINE=/usr/local/bin/wine64 sh winetricks d3dcompiler_43 to install the required DLL from the DirectX redistributable (this is a smaller download than the SDK).
