Glslang-15.0.0

Introduction to Glslang

The Glslang package contains an frontend and validator for OpenGL, OpenGL ES, and Vulkan shaders.

[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

Glslang Dependencies

Required

CMake-3.31.0 and SPIRV-Tools-1.3.296.0

Installation of Glslang

Install Glslang by running the following commands:

mkdir build &&
cd    build &&

cmake -D CMAKE_INSTALL_PREFIX=/usr     \
      -D CMAKE_BUILD_TYPE=Release      \
      -D ALLOW_EXTERNAL_SPIRV_TOOLS=ON \
      -D BUILD_SHARED_LIBS=ON          \
      -D GLSLANG_TESTS=ON              \
      -G Ninja .. &&
ninja

To test the results, issue: ninja test.

Now, as the root user:

ninja install

Command Explanations

-D ALLOW_EXTERNAL_SPIRV_TOOLS=ON: This switch allows the build system to use the system-installed copy of SPIRV-Tools-1.3.296.0, instead of downloading and installing it's own copy.

-D BUILD_SHARED_LIBS=ON: This switch builds shared versions of the libraries, and does not install static versions of them.

-D GLSLANG_TESTS=ON: This switch builds the tests for the package.
