Building and Running BetheAnsatz

Required Software

  • GNU C++
  • The LAPACK and BLAS libraries
  • The GSL library
  • PsimagLite (see below)

Optional Software

  • make or gmake (only needed to use the Makefile)
  • perl (may be needed to run some auxiliary script)

Quick Start

  1. Use your distribution repository tool to install gcc with support for C++, the LAPACK and BLAS libraries, the gsl library, make, perl, and git if you don't have them.

  2. Issue

    cd someDirectory/

    git clone https://github.com/g1257/PsimagLite.git

    git clone https://github.com/g1257/BetheAnsatz.git

  3. Compile PsimagLite

  4. Now issue

    cd BetheAnsatz/src

    cp Config.make.sample Config.make

    make

  5. You can run it with TBW.
