Installation
============
Prerequisite
------------
2013-08-27 19:17:17 +02:00
The TRIQS library relies on a certain number of standard libraries and tools described in
the :ref:`list of requirements <requirements>`. Beware in particular to the :ref:`C++ compilers<require_cxx_compilers>`
and to :ref:`Scientific Python tools<python_install>`.
Here are instructions to install
these necessary libraries on two standard systems:
.. toctree::
:maxdepth: 1
installation/ubuntu
installation/osx_lion
Installation steps
------------------
#. Download the sources of TRIQS from github into a ``src`` directory::
$ git clone git@github.com:TRIQS/triqs.git src
#. Create an empty build directory where you will compile the code::
$ mkdir build && cd build
#. In the build directory call cmake specifying where the TRIQS library should be installed::
$ cmake -DCMAKE_INSTALL_PREFIX=path_to_install_directory ../src

If you omit CMAKE_INSTALL_PREFIX, the default `path_to_install_directory` is ./INSTALL_DIR.
Configuration options are described :ref:`here<install_options>`.
#. Compile the code, run the tests and install the library::
$ make
$ make test
$ make install
2013-08-27 19:17:17 +02:00
.. note::
We remind you that on multicore machine, make's option -jN (where N is the number of cores)
greatly speed up the compilation e.g. make -j8 on a 8 cores machine...
#. After the installation TRIQS has been installed using the standard UNIX
scheme:
* executables in ``path_to_install_directory/bin``.
* c++ and python libraries in ``path_to_install_directory/lib``.
* c++ headers in ``path_to_install_directory/include/triqs``.
* shared items in ``path_to_install_directory/share/triqs``.
