This version of BLFS may not build or run some packages properly if LFS or dependencies have been updated since the most recent stable version of the System V books.

Package Information

Glslang Dependencies

Required

CMake-4.2.3 and SPIRV-Tools-1.4.341.0

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-1.4.341.0, 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.
