.. 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.
