Eigen 3.3.7

Tested on (Requirements)

  • OS base: CentOS (x86_64) \(\boldsymbol{\ge}\) 6.6 (Rocks 6.2)

Dependencies

Eigen [1] doesn’t have any dependencies other than the C++ standard library. Eigen uses the CMake build system, but only to build the documentation and unit-tests, and to automate installation. If you just want to use Eigen, you can use the header files right away. There is no binary library to link to, and no configured header file. Eigen is a pure template library defined in the headers.

Installation

  1. Download the latest version of Eigen and unzip the file

    $ wget https://gitlab.com/libeigen/eigen/-/archive/3.3.7/eigen-3.3.7.tar.gz
$ tar -xzvf eigen-3.3.7.tar.gz

  2. Inside the folder, on the top create a build directory where the installation binaries will be put by cmake.

    $ cd eigen-3.3.7
$ mkdir build
$ cd build

  3. Load the necessary modules for the building.

    $ module load cmake/3.7.1
$ module load intel/19.0.4
$ module load boost/1.62.0_gcc-5.4.0_openmpi-1.8.8-x86_64

  4. Execute the cmake command with the desired directives.

    $  cmake ..  -DCMAKE_C_COMPILER=icc -DCMAKE_CXX_COMPILER=icpc -DCMAKE_INSTALL_PREFIX=/share/apps/eigen/3.3.7/intel-19.0.4

  5. Execute the make commands sequence.

    $ make -j <N>
$ make check
$ make -j <N> install

Warning

Some tests may fail, but the installation can continue depending on the number of failed tests.
