Introduction to Glslang
The Glslang package contains an
frontend and validator for OpenGL, OpenGL ES, and Vulkan shaders.
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
32-bit Installation of Glslang
First clean the build directory:
rm -rf *
Install lib32-Glslang by running
the following commands:
CC="gcc -m32" CXX="g++ -m32" \
PKG_CONFIG_PATH=/usr/lib32/pkgconfig \
cmake -D CMAKE_INSTALL_PREFIX=/usr \
-D CMAKE_INSTALL_LIBDIR=lib32 \
-D CMAKE_BUILD_TYPE=Release \
-D ALLOW_EXTERNAL_SPIRV_TOOLS=ON \
-D BUILD_SHARED_LIBS=ON \
-D GLSLANG_TESTS=ON \
-G Ninja .. &&
ninja
Now, as the root user:
DESTDIR=$PWD/DESTDIR ninja install &&
cp -vr DESTDIR/usr/lib32/* /usr/lib32 &&
rm -rf DESTDIR &&
ldconfig
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.
