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).

[Note]

Note

Development versions of BLFS may not build or run some packages properly if LFS or dependencies have been updated since the most recent stable versions of the books.

Package Information

Glslc Dependencies

Required

CMake-3.30.3, Glslang-14.3.0, and SPIRV-Tools-1.3.290.0

Installation of glslc

First, allow building with system Glslang-14.3.0 and SPIRV-Tools-1.3.290.0: 

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 '"2024.2"' > glslc/src/build-version.inc

Now install glslc by running the following commands: 

mkdir build &&
cd    build &&

cmake -D CMAKE_INSTALL_PREFIX=/usr \
      -D CMAKE_BUILD_TYPE=Release  \
      -D SHADERC_SKIP_TESTS=ON     \
      -G Ninja ..
ninja

Now, as the root user: 

install -vm755 glslc/glslc /usr/bin
