Build the Library
Ensure that all software dependencies are in place and have at least the minimal supported version.
The oneDNN build system is based on CMake. Use
CMAKE_INSTALL_PREFIX
to control the library installation location,
CMAKE_BUILD_TYPE
to select between build type (Release
, Debug
, RelWithDebInfo
).
See Build Options for detailed description of build-time configuration options.
Linux/macOS
Prepare the Build Space
mkdir -p build && cd build
Generate makefile
- Native compilation:
cmake .. <extra build options>
- Cross compilation (AArch64 target on Intel 64 host)
export CC=aarch64-linux-gnu-gcc
export CXX=aarch64-linux-gnu-g++
cmake .. \
-DCMAKE_SYSTEM_NAME=Linux \
-DCMAKE_SYSTEM_PROCESSOR=AARCH64 \
-DCMAKE_LIBRARY_PATH=/usr/aarch64-linux-gnu/lib \
<extra build options>
Build and Install the Library
- Build the library:
- Build the documentation:
- Install the library, headers, and documentation:
Windows
- Generate a Microsoft Visual Studio solution:
mkdir build && cd build && cmake -G "Visual Studio 15 2017 Win64" ..
For the solution to use the Intel C++ Compiler, select the corresponding toolchain using the cmake -T
switch: cmake -G "Visual Studio 15 2017 Win64" -T "Intel C++ Compiler 19.0" ..
- Build the library: You can also use the
msbuild
command-line tool directly (here /p:Configuration
selects the build configuration which can be different from the one specified in CMAKE_BUILD_TYPE
, and /m
enables a parallel build): msbuild "oneDNN.sln" /p:Configuration=Release /m
- Build the documentation
cmake --build . --target DOC
- Install the library, headers, and documentation:
cmake --build . --target INSTALL
Validate the Build
If the library is built for the host system, you can run unit tests using:
