.. index:: Required libraries .. _requirements: A complete list of requirements =============================== TRIQS is built upon several python and C++ libraries, which, if not present already in your system, can be freely downloaded and installed. All the libraries and tools used by TRIQS are described below. .. _require_cxx_compilers: C++ compilers ------------- TRIQS is written in C++, i.e. in the **C++11** standard as defined by the ISO standardization committee. A recent compiler is therefore mandatory. * Standard compliant C++ compilers (recommended and supported). * :ref:`clang 3.2` and higher (in particular the default clang on OS X 10.8). * g++ 4.8.1 and higher * The intel icc 14.0 is close to be C++11 compliant, but presents currently too many bugs to be supported at present. It compiles 99% of TRIQS, but we do not have the ressources to write and maintains all necessary workarounds. Besides, for *our codes*, icc does not provide a significant speed gain (unlike MKL), so we do not recommend it for TRIQS. * C++98 compilers * g++ before 4.8.1 * Intel icc 13.0 and below Compilers implementing the previous version of the C++ standard (C++98) do not work and will *not* be supported. Libraries --------- ================== ================ ================================================================================ Library/tool Version Comment ================== ================ ================================================================================ mpi openmpi Parallelism. Since standard linux distributions (and macports on OS X) now provides openmpi, even on laptops, we avoid the unnecessary complication of maintaining a non-parallel version of TRIQS fftw >= 3.2 Fourier transforms boost >= 1.49 C++ librairies hdf5 >= 1.8.0 File storage system. Important: the *serial* version must be installed python >= 2.6.5 The Python interpreter scipy Python mathematical library numpy Python scientific library h5py Python interface to hdf5 library mpi4py Python MPI sphinx >= 1.0.1 Python documentation tools (to compile documentation) cmake >= 2.8.7 CMake is used to control the software compilation process pyparsing Tool for sphinx (to compile documentation) matplotlib >= 0.99 Python 2D plotting library cython >=0.17 A language that allows to write C extensions for the Python language ================== ================ ================================================================================
