Build from Source

Download the Source Code

Download DNNL source code or clone the repository.

git clone https://github.com/intel/mkl-dnn.git

Build the Library

Ensure that all software dependencies are in place and have at least the minimal supported version.

The DNNL 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

• Generate makefile:

  mkdir -p build && cd build && cmake ..

• Build the library:

  make -j

• Build the documentation:

  make doc

• Install the library, headers, and documentation:

  make install

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:

  cmake --build .

  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 "DNNL.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

Run unit tests:

ctest
