Installation
|
|
============
|
|
|
|
TRIQS and its applications are provided *à la carte*:
|
|
after you have installed the TRIQS toolkit, you will be able to easily install
|
|
various TRIQS-based applications: impurity solvers, realistic DMFT tools, ...
|
|
|
|
This page describes the installation of the TRIQS toolkit itself. The installation of the applications
|
|
is described in their respective documentation.
|
|
|
|
Prerequisite
|
|
------------
|
|
|
|
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:

Installation steps
|
|
------------------
|
|
|
|
#. Download the sources of TRIQS from github into a ``src`` directory::
|
|
|
|
$ git clone https://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 the subdirectory *INSTALL_DIR* in your build
|
|
directory. More configuration options are described in the
|
|
:ref:`cmake options <install_options>`.
|
|
|
|
#. Compile the code, run the tests and install the library::
|
|
|
|
$ make
|
|
$ make test
|
|
$ make install
|
|
|
|
.. note::
|
|
|
|
We remind you that on multicore machine, make's option -jN (where N is the number of cores)
|
|
greatly speeds up the compilation, e.g. make -j8 on an 8 core 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 (e.g. the documentation) in ``path_to_install_directory/share/triqs``.
