SPIRV-LLVM-Translator-21.1.1

Introduction to SPIRV-LLVM-Translator

SPIRV-LLVM-Translator is a tool and a library for bi-directional translation between SPIR-V and LLVM IR.

SPIRV-LLVM-Translator Dependencies

Required
CMake-4.1.2, libxml2-2.15.1, LLVM-21.1.2 (with Clang), and Vulkan-SDK-1.4.328.1

Installation of SPIRV-LLVM-Translator

Install SPIRV-LLVM-Translator by running the following commands: 

mkdir build &&
cd    build &&

cmake -D CMAKE_INSTALL_PREFIX=/usr                   \
      -D CMAKE_BUILD_TYPE=Release                    \
      -D CMAKE_SKIP_INSTALL_RPATH=ON                 \
      -D BUILD_SHARED_LIBS=ON                        \
      -D LLVM_EXTERNAL_SPIRV_HEADERS_SOURCE_DIR=/usr \
      -G Ninja .. &&

ninja

Now, as the root user: 

ninja install

lib32 Installation of SPIRV-LLVM-Translator

Install lib32-SPIRV-LLVM-Translator by running the following commands: 

rm -rf * &&
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 CMAKE_SKIP_INSTALL_RPATH=ON                 \
      -D BUILD_SHARED_LIBS=ON                        \
      -D LLVM_EXTERNAL_SPIRV_HEADERS_SOURCE_DIR=/usr \
      -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

[Note]

Note

For a full list of options and values, make sure you are in a build directory, then run cmake -LAH ...

-D CMAKE_SKIP_INSTALL_RPATH=ON: This switch makes cmake remove hardcoded library search paths (rpath) when installing a binary executable file or a shared library. This package does not need rpath once it's installed into the standard location, and rpath may sometimes cause unwanted effects or even security issues.

-D BUILD_SHARED_LIBS=ON: This switch forces the build system to install shared libraries instead of static libraries.

-D LLVM_EXTERNAL_SPIRV_HEADERS_*: These switches tells the build system that Vulkan-SDK-1.4.328.1 is installed in /usr. This is needed since the build system tries to download and use the downloaded headers not on the system if the switch isn't invoked.
