Installing kratos in Ubuntu Linux

From KratosWiki

The objective of current tutorial is to "standardize" the installation of Kratos on an Ubuntu system. Please note that 90% of the operations described are necessary for the installation of libraries in the system rather than for the compilation of the Kratos itself.

SYSTEM LIBRARIES INSTALL

Set the download server to "main server". This can be done operning the Synaptic Package Manager and going to Settings-Repository : in the section Ubuntu Software change the option Download from: Main server

we detail here the installation of some basic packages. Note that not all of the packages are strictly needed however our advice is to install all of them if you are not sure of what you are doing

essential packages:

  sudo apt-get install -y build-essential
  sudo apt-get install -y subversion
  sudo apt-get install -y rapidsvn
  sudo apt-get install -y libblas3gf
  sudo apt-get install -y liblapack3gf
  sudo apt-get install -y libblas-dev
  sudo apt-get install -y liblapack-dev
  sudo apt-get install -y python-dev
  sudo apt-get install -y gfortran
  sudo apt-get install -y csh
  sudo apt-get install -y swig
  sudo apt-get install -y python-matplotlib

useful packages (not strictly needed for the kratos):

  sudo apt-get install -y emacs
  sudo apt-get install -y kate
  sudo apt-get install -y python-scipy
  sudo apt-get install -y python-numpy
  sudo apt-get install -y python-scientific


  sudo apt-get install -y g++
  sudo apt-get install -y python

IF YOU DON'T NEED MPI

BOOST library:

You can download the late release of boost libraries from boost web page or you can use directly the boost libraries that you find in the repositories by typing

  sudo apt-get install libboost-all-dev
  sudo apt-get install libboost-dbg

IF YOU NEED MPI

install the packages

  sudo apt-get install -y openmpi-bin
  sudo apt-get install -y openmpi-dev
  sudo apt-get install -y libparmetis3.1
  sudo apt-get install -y libparmetis-dev   

then install the boost_mpi packages:

  sudo apt-get install libboost-mpi-python-dev
  sudo apt-get install libboost-mpi-pythonX.XX.XX

note that the X.XX.X is to be replaced with the version of the lib that comes with the system

ALTERNATIVELY, and just if you have a very good reason to do it, you can compile manually the boost library including mpi, which can be done by following the instructions at How to compile the Boost if you want to use MPI

GET KRATOS

Follow the instructions of How to get Kratos to create your local kratos copy.

Kratos Libraries

The installer now performs automatically the compilation of the libraries needed

COMPILE THE KRATOS

The compilation of the Kratos is now cmake-based. Cmake can be installed in the system by simply typing

 sudo apt-get install cmake

HOWEVER please note that cmake is improving very fast and the "cmake-experience" improves with every release, as a consequence we advise to download and install the latest cmake release

once cmake is installed in the system go to the directory

  cd cmake_build 

then copy

  cp example_configure.sh.do_not_touch configure.sh

edit "configure.sh" to activate libs as you wish (or leave it as it is for the defaults), and finally run

  sh configure.sh

and the kratos should compile and install

Detailed README instructions are available in the directory "cmake_build"

CREATE IN DEBUG

Debug compilation can be obtained by simply substituting "Release" --> "Debug" within your "configure.sh". Alternative options are "RelWithDebInfo" and "MinSizeRel"

If you want to have available both a release build and a debug build, just create another directory (say cmake_debug_build), copy into it your configure file and run it from that directorye

FINAL STEP

you have to let the system know where the kratos is installed

this can be done by adding the line (assuming kratos is installed in "${HOME}/kratos/libs"

 export PYTHONPATH=${HOME}/kratos/libs:$PYTHONPATH
 export PYTHONPATH=${HOME}/kratos:$PYTHONPATH

to the ".bashrc" (a hidden configuration file in the home directory)

Additionally you may have to add your "${HOME}/kratos/libs" directory to LD_LIBRARY_PATH. This can be done adding these lines:

 export LD_LIBRARY_PATH=${HOME}/kratos/libs:$LD_LIBRARY_PATH

to the ".bashrc"
