dynamic-graph

This software provides an efficient way to modelize a C++ data-flow.

A dynamic graph data-flow is composed of:

• entities (graph nodes)
• signals (input/output of a graph action)

Output signals can then be plugged into input signals to data transmission.

An efficient caching mechanism avoid useless data recomputation and a simple built-in language can be used to control the graph actions.

It is released under the BSD-clause 2 license.

Documentation

To get started with this library, please read the [online Doxygen documentation][doxygen-documentation].

It can also be generated locally by running the make doc command. After the package is installed, the documentation will be located in the $prefix/share/doc/dynamic-graph directoy where $prefix is your installation prefix (/usr/local by default).

Getting Help

Support is provided through issues on the github interface.

How can I install dynamic-graph?

Installing dependencies

The matrix abstract layer depends on several packages which have to be available on your machine.

• Libraries:
  • [Boost][] (>= 1.40)
  • Doxygen
  • Eigen3
  • pthread
• System tools:
  • [CMake][] (>=2.6)
  • [pkg-config][]
  • usual compilation tools (GCC/G++, make, etc.) If you are using Ubuntu, these tools are gathered in the build-essential package.

Compiling and installing the package

The manual compilation requires two steps:

1. configuration of the build and generation of the build files
2. compilation of the sources and installation of the package

dynamic-graph uses [CMake][] to generate build files. It is recommended to create a separate build directory:

mkdir _build         # (1) Create a build directory
cd _build            # (2) Go to the newly created build directory
cmake [options] ..   # (3) Generate the build files

Options which can be passed to CMake are detailed in the next section.

make                 # (4) Compile the package
make test            # (5) Execute the package tests
make install         # (6) Install the package into the prefix (see step 3)

Options

Additional options can be set on the command line through the following command: -D<option>=<value>.

For instance: cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo .. will set the CMAKE_BUILD_TYPE option to the value RelWithDebInfo.
