Currently two platforms are known to work:

  • Ubuntu 16.04
  • CentOS 7.4

Ubuntu 16.04 Prerequisites

Compilers currently known to work are gcc-5.4.0, clang-3.9, and gcc-4.8.5.

If you are using gcc-5.4.0 or clang-3.9, it is recommended to add the option -DNGRAPH_USE_PREBUILT_LLVM=TRUE to the cmake command. This causes the build system to fetch a pre-built tarball of LLVM+Clang from llvm.org, which substantially cuts down on build times.

If you are using gcc-4.8, it may be necessary to add symlinksfrom gcc to gcc-4.8, and from g++ to g++-4.8, in your PATH, even if you have specify CMAKE_C_COMPILER and CMAKE_CXX_COMPILER when building. (You should NOT supply the -DNGRAPH_USE_PREBUILT_LLVM flag in this case, because the prebuilt tarball supplied on llvm.org is not compatible with a gcc-4.8 based build.)

CentOS 7.4 Prerequisites

CentOS supplies an older version of CMake that is not compatible with LLVM-5.0.1, which we build as an external dependency. There are two options:

  1. (requires root privileges) install the the cmake3 package from EPEL, or
  2. (does not require root privileges) build CMake (3.1 or newer) from source, and run it from its build directory.

General Instructions

These instructions assume that your system has been prepared in accordance with the above prerequisites.

$ cd ngraph
$ mkdir build
$ cd build
$ cmake .. \
    -DCMAKE_C_COMPILER=<path to C compiler> \
    -DCMAKE_CXX_COMPILER=<path to C++ compiler>
$ make -j install
