Package Information

Glslang Dependencies

Required

CMake-3.28.1 and SPIRV-Tools-2023.5.rc1

Installation of Glslang

Install Glslang by running the following commands: 

mkdir build &&
cd    build &&

cmake -DCMAKE_INSTALL_PREFIX=/usr     \
      -DCMAKE_BUILD_TYPE=Release      \
      -DALLOW_EXTERNAL_SPIRV_TOOLS=ON \
      -DBUILD_SHARED_LIBS=ON          \
      -G Ninja .. &&
ninja

To test the results, issue: ninja test.

Now, as the root user: 

ninja install

Command Explanations

-DALLOW_EXTERNAL_SPIRV_TOOLS=ON: This switch allows the build system to use the system-installed copy of SPIRV-Tools-2023.5.rc1, instead of downloading and installing it's own copy.

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