Glslang Zig

Glslang ported to the Zig build system.

Contributions or bug reports are welcome if behavior differs from official build system.

Usage

See shader_compiler for example usage.

Version

See build.zig.zon for current version info. Dependencies will be updated to point at the next glslang release when it's available (this commit is necessary for a good debug build experience.)

Known Differences

• The official build process has a web target for the glslang artifact, but this project does not. Contributions are welcome.
• The official build process symlinks glslang to glslangValidator. This build outputs glslangValidator instead of glslang and does not provide a symlink because the library artifact is already named glslang.
• The tests are not built.
• Compiler flags for exceptions, rtti, etc are not configurable (see build.zig for current values.)

How To Change the Glslang Version

The version of glslang is set in build.zig.zon.

Glslang depends on SPIRV-Headers, and SPIRV-Tools. When changing the glslang version you may need to update these dependencies, to find out if this is necessary check your glslang's known-good.json.

Glslang and SPIRV-Tools' official build processes generate headers at compile time. These are cached in the generated directory, and can be regenerated via the official build processes.
