Installation

Yade can be installed from packages (precompiled binaries) or source code. The choice depends on what you need: if you don’t plan to modify Yade itself, package installation is easier. In the contrary case, you must download and install source code.

Packages

Pre-built packages are provided for all currently supported Debian and Ubuntu versions of distributions and available on yade-dem.org server.

These are daily versions of packages and are updating regularly and include all the newly added features.

To install daily-version one needs to add this repository to your /etc/apt/sources.list, add a PGP-key AA915EEB as a trusted and install yadedaily

sudo bash -c 'echo "deb http://www.yade-dem.org/packages/ precise/" >> /etc/apt/sources.list'
wget -O - http://www.yade-dem.org/packages/yadedev_pub.gpg | sudo apt-key add -
sudo apt-get install yadedaily

If you have another distribution, not Ubuntu Precise, be sure to use the correct name in the first line (for instanse, jessie, trusty or wheezy).

After that you can normally start Yade using “yadedaily” or “yadedaily-batch” command.

Git-repository for packaging stuff is available on GitHub. Each branch corresponds to one distribution e.g. precise, jessie etc. The scripts for building all of this stuff is here. It uses pbuilder to build packages, so all packages are building in a clean environment.

If you do not need yadedaily-package any more, just remove the corresponding line in /etc/apt/sources.list. To remove our key from keyring, execute the following commands:

sudo apt-key remove AA915EEB
sudo apt-get purge yadedaily

Since 2011 all Ubuntu versions (starting from 11.10, Oneiric) and Debian (starting from Wheezy) are having already Yade in their main repositories. There are only stable releases are placed. To install the program, run the following:

sudo apt-get install yade

To check, what version of Yade is in specific Distribution, check the links for Ubuntu and Debian.

Source code

Installation from source code is reasonable, when you want to add or modify constitutive laws, engines or functions... Installing the latest trunk version allows one to use newly added features, which are not yet available in packaged versions.

Download

If you want to install from source, you can install either a release (numbered version, which is frozen) or the current developement version (updated by the developers frequently). You should download the development version (called trunk) if you want to modify the source code, as you might encounter problems that will be fixed by the developers. Release version will not be modified (except for updates due to critical and easy-to-fix bugs), but they are in a more stabilized state that trunk generally.

  1. Releases can be downloaded from the download page, as compressed archive. Uncompressing the archive gives you a directory with the sources.
  2. developement version (trunk) can be obtained from the code repository at github.

We use GIT (the git command) for code management (install the git package in your distribution and create a GitHub account):

git clone git@github.com:yade/trunk.git

will download the whole code repository of trunk. Check out Yade on github wiki page for more.

Alternatively, a read-only checkout is possible via https without a GitHub account (easier if you don’t want to modify the main Yade branch):

git clone https://github.com/yade/trunk.git

For those behind firewall, you can download any revision of the repository as compressed archive.

Release and trunk sources are compiled in the same way.

Prerequisites

Yade relies on a number of external software to run; they are checked before the compilation starts. Some of them are only optional. The last ones are only relevant for using the fluid coupling module (FlowEngine).

Most of the list above is very likely already packaged for your distribution. The following commands have to be executed in command line of corresponding distributions. Just copy&paste to the terminal. To perform commands you should have root privileges

Warning

If you have Ubuntu 12.10 or older, you need to install libqglviewer-qt4-dev package instead of libqglviewer-dev.

  • Ubuntu, Debian and their derivatives:

    sudo apt-get install cmake git freeglut3-dev libloki-dev \
    libboost-all-dev fakeroot dpkg-dev build-essential g++ \
    python-dev ipython python-matplotlib libsqlite3-dev python-numpy python-tk gnuplot \
    libgts-dev python-pygraphviz libvtk5-dev python-scientific libeigen3-dev \
    python-xlib python-qt4 pyqt4-dev-tools gtk2-engines-pixbuf python-argparse \
    libqglviewer-dev python-imaging libjs-jquery python-sphinx python-git python-bibtex \
    libxmu-dev libxi-dev libcgal-dev help2man libbz2-dev zlib1g-dev \

Some of packages (for example, cmake, eigen3) are mandatory, some of them are optional. Watch for notes and warnings/errors, which are shown by cmake during configuration step. If the missing package is optional, some of Yade features will be disabled (see the messages at the end of configuration).

Additional packages, which can become mandatory later:

sudo apt-get install python-gts python-minieigen \

For effective usage of direct solvers in the fluid coupling, the following libraries are recommended, together with eigen>=3.1: blas, lapack, suitesparse, and metis. All four of them are available in many different versions. Different combinations are possible and not all of them will work. The following was found to be effective on ubuntu 12.04 and debian wheezy. (openblas provides its own version of lapack, and suitesparse-metis will trigger the installation of parmetis):

sudo apt-get install libopenblas-dev libsuitesparse-metis-dev \

Some packages listed here are relatively new and they can be absent in your distribution (for example, libmetis-dev or python-gts). They can be installed from our external PPA or just ignored. In this case some features can be disabled.

If you are using other distribuition, than Debian or its derivatives, you should install the softwares listed above. Their names can differ from the names of Debian-packages.

Compilation

You should create a separate build-place-folder, where Yade will be configured and where the source code will be compiled. Then inside this build-directory you should start cmake to configure the compilation process:

cmake -DINSTALL_PREFIX=/path/to/installfolder /path/to/sources

Additional options can be configured in the same line with the following syntax:

cmake -DOPTION1=VALUE1 -DOPTION2=VALUE2

The following options are available:

  • INSTALL_PREFIX: path where Yade should be installed (/usr/local by default)
  • LIBRARY_OUTPUT_PATH: path to install libraries (lib by default)
  • DEBUG: compile in debug-mode (OFF by default)
  • CMAKE_VERBOSE_MAKEFILE: output additional information during compiling (OFF by default)
  • SUFFIX: suffix, added after binary-names (version number by default)
  • NOSUFFIX: do not add a suffix after binary-name (OFF by default)
  • YADE_VERSION: explicitely set version number (is defined from git-directory by default)
  • ENABLE_GUI: enable GUI option (ON by default)
  • ENABLE_CGAL: enable CGAL option (ON by default)
  • ENABLE_VTK: enable VTK-export option (ON by default)
  • ENABLE_OPENMP: enable OpenMP-parallelizing option (ON by default)
  • ENABLE_GTS: enable GTS-option (ON by default)
  • ENABLE_GL2PS: enable GL2PS-option (ON by default)
  • ENABLE_LINSOLV: enable LINSOLV-option (ON by default)
  • ENABLE_PFVFLOW: enable PFVFLOW-option, FlowEngine (ON by default)
  • runtimePREFIX: used for packaging, when install directory is not the same is runtime directory (/usr/local by default)
  • CHUNKSIZE: used, if you want several sources to be compiled at once. Increases compilation speed and RAM-consumption during it (1 by default).

For using an extended parameters of cmake, please, follow the corresponding documentation on cmake-webpage.

If the compilation is finished without errors, you will see all enabled and disabled options. Then start the standard the compilation process:

make

Installing performs with the following command:

make install

The “install” command will in fact also recompile if source files have been modified. Hence there is no absolute need to type the two commands separately.

The compilation process can take a long time, be patient. An additional parameter on many cores systems -j can be added to decrease compilation time and split the compilation on many cores. For example, on 4-core machines it would be reasonable to set the parameter -j4. Note, the Yade requires approximately 2GB/core for compilation, otherwise the swap-file will be used and a compilation time dramatically increases.

For building the documentation you should at first execute the command “make install” and then “make doc” to build it. The generated files will be stored in your current build directory/doc/sphinx/_build.

“make manpage” command generates and moves manpages in a standard place. “make check” command executes standard test to check the functionality of compiled program.

Yade can be compiled not only by GCC-compiler, but also by CLANG front-end for the LLVM compiler. For that you set the environment variables CC and CXX upon detecting the C and C++ compiler to use:

export CC=/usr/bin/clang
export CXX=/usr/bin/clang++
cmake -DOPTION1=VALUE1 -DOPTION2=VALUE2

Clang does not support OpenMP-parallelizing for the moment, that is why the feature will be disabled.
