Laura++ paper

A paper describing the package has recently been published under an Open Access agreement in Computer Physics Communications:
It is also available from the arXiv:

Getting the code

Following the migration of the HepForge site to use Phabricator, anonymous checkout from SVN is currently not possible.
For the time being you can instead download a tar file of the source from the download area, which contains gzipped tar files of all tagged versions.
We plan to migrate the repository to git in the near future.

In order to keep up to date with announcements of new releases etc. please subscribe to the laura-announce mailing list.

Compiling the code

The package depends only on ROOT. Before building the code, it is necessary that either the ROOTSYS environment variable be set or that the root-config program be in the PATH.

The code is compiled using a Makefile, which should work on Linux and MacOSX. Simply run make in the top level directory and the library should appear in the lib subdirectory.

We plan to eventually use CMake for the build system, which should allow greater portability.

Getting started

You can find an initial quick-start guide here, which introduces some of the code in the examples/ subdirectory of the package. In particular, it describes the main features of the example The examples can be compiled by running make in that directory.


Each released version of the code comes with accompanying doxygen documentation. The latest release is always directly linked here, or you can browse for a specific release.

Submitting bug reports or feature requests

Following the migration of HepForge to Phabricator we need to migrate our bug tracking to the new interface.
For the time being, please report issues to the developer mailing list.
