Introduction to glslc

The glslc program is Google's command line compiler for OpenGL Shading Language/High Level Shading Language (GLSL/HLSL) to Standard Portable Intermediate Representation (SPIR-V).

This package is known to build and work properly using an LFS 12.4 platform.

Package Information

Glslc Dependencies

Required

CMake-4.1.3, Glslang-16.0.0, and SPIRV-Tools-1.4.328.1

Installation of glslc

First, allow building with system Glslang-16.0.0 and SPIRV-Tools-1.4.328.1: 

sed '/build-version/d'   -i glslc/CMakeLists.txt
sed '/third_party/d'     -i CMakeLists.txt
sed 's|SPIRV|glslang/&|' -i libshaderc_util/src/compiler.cc

echo '"2025.4"' > glslc/src/build-version.inc

Now Prepare glslc by running the following commands: 

cmake -B build -G Ninja            \
      -D CMAKE_INSTALL_PREFIX=/usr \
      -D CMAKE_BUILD_TYPE=Release  \
      -D SHADERC_SKIP_TESTS=ON
ninja -C build

Now Install the package, as the root user: 

install -vm755 glslc/glslc /usr/bin
