.. index:: dependencies .. _dependencies: A complete list of dependencies ================================== 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 listed in the table : ================== ================ ================================================================================ Libraries/tools Version Comment ================== ================ ================================================================================ mpi e.g., 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 transform boost >= 1.49 C++ librairies hdf5 >= 1.8.0 File storage system. Important: the *serial* version must be installed python* >= 2.6.5 scipy* python mathematical library numpy* python scientific library h5py* python interface to hdf5 library sphinx* >= 1.0.1 python documentation tools (to compile documentation) pyparsing* Tool for sphinx (to compile documentation) matplotlib* >= 0.99 python 2D plotting library cython >=0.17 [DEVELOPERS ONLY] ================== ================ ================================================================================ \* designates the libraries included in the Enthought python distribution. C++11 -------- The current version of TRIQS use the new C++11 standard, and therefore require a recent C++ compiler. Tested compilers include : * g++ 4.6.3, 4.7 * clang++ 3.1 * icc 13.0 Note that older compilers will *never* be supported for current and future version of TRIQS. Older releases may accept older compilers. F90 ------- For the Wien2TRIQS interface only. Tested compilers include : * ifort * gfortran Boost -------------------------- The boost library is often upgraded, and it is rare to have the correct version in your distribution. TRIQS installation process offers two choices : * Recommended choice: As explained in the :ref:`page above `, you can download simply the latest *sources* and TRIQS will do all the job for you by compiling the pieces of boost that are needed in a little boost_for_triqs library. * OR you can include and link with an installed boost if the version if high enough as discussed in :ref:`install_options`.
