Introduction to Glslang
The Glslang package contains an
frontend and validator for OpenGL, OpenGL ES, and Vulkan shaders.
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-4.1.2 and SPIRV-Tools-1.4.321.0
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-1.4.321.0, 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.
