LTSmin is a toolset for manipulating labelled transition systems. The main tool in this release is ltsmin-mpi, which is a distributed implementation of signature-based bisimulation reduction for strong bisimulation and branching bisimulation. The input for this tool is a labelled transition system (LTS) in DIR format.

Various sequential, symbolic and distributed tools are provided for the creation of LTSs, for example from muCRL, mCRL2 and PROMELA (via NIPS) specifications. Alternatively, LTSs in DIR format can be created by third-party tools, for example instantiators and dmp2dir from the muCRL toolset.

The tools in this release support compression of DIR files as well as putting a DIR in an archive file. The ltsmin-convert utility can convert files from one DIR variant to another, and to the BCG file format from the CADP toolset.

Installation Instructions

If you are building the software from a Git repository rather than a release tarball, refer to Section "Building from a Git Repository" for additional set-up instructions. Then install the dependencies listed in Section "Build Dependencies" below.

# Unpack the tarball
$ tar xvzf ltsmin-<version>.tar.gz
$ cd ltsmin-<version>

# Configure
$ ./configure --disable-dependency-tracking --prefix /path/

It is a good idea to check the output of ./configure, to see whether all dependencies were found.

# Build
$ make

# Install
$ make install

Additional Build Options

configure Options

For one-shot builds, the following option speeds up the build process by not recording dependencies:

./configure --disable-dependency-tracking ...

Non-standard compilers, etc., can be configured by using variables:

./configure CFLAGS='-O3' CXXFLAGS='-O3'                \
            CC='gcc -m64'                              \
            MPICC='/sw/openmpi/1.2.8/bin/mpicc -m64'   \
            MPICXX='/sw/openmpi/1.2.8/bin/mpicxx -m64' \
            ...

This would add some options to the standard CFLAGS and CXXFLAGS settings used for building to enable more optimizations and force a 64-bit build (for the GCC C compiler). Furthermore, the MPI compiler wrappers are set explicitly instead of searching them in the current shell PATH.

Note that for libraries installed in non-standard places need special attention: to be picked up by the configure script, library and header search paths must be added, e.g.:

    ./configure LDFLAGS=-L/opt/local/lib CPPFLAGS=-I/opt/local/include

Additional setting of (DY)LD_LIBRARY_PATH might be needed for the dynamic linker/loader (see, e.g., "man ld.so" or "man dyld").

See ./configure --help for the list of available variables, and file INSTALL for further details.

make Targets

The following additional make targets are supported:

all
Builds everything.
install
Installs the software into path $prefix (default: /usr/local/).
mostlyclean
clean
distclean
Clean the source tree to various degrees. Using mostlyclean is enough in many cases.
doxygen-doc
Builds Doxygen documentation for the source code.

Build Dependencies

We list the external libraries and tools which are required to build this software.

popt

Download popt (>= 1.7) from <http://rpm5.org/files/popt/>. We tested with popt 1.14.

zlib

Download zlib from <http://www.zlib.net/>.

GNU make

Download GNU make from <http://www.gnu.org/software/make/>.

Optional Dependencies

muCRL

Download muCRL from <http://www.cwi.nl/~mcrl/mutool.html>. We tested with muCRL-2.18.4. Without muCRL, the distributed tool for state space generation (lpo2lts-mpi) will not be built, and neither will all NIPS-based tools.

mCRL2

Download the latest released version of mCRL2 from <http://www.mcrl2.org/>. We tested with mcrl2-200901. Build and install mCRL2 as usual:

./configure <options>
make
make install

Unless mcrl2 is configured to use an external Boost library instead of its own copy, the headers have to be installed as well:

./build/bin/bjam --install --install-boost-headers

Ensure that these headers are actually used to compile the PINS support for mcrl2 (instead of, e.g., system-provided Boost headers).

CADP

See the CADP website on how to obtain a licence and download the CADP toolkit.

MPI

In principle, any MPI library which supports MPI-IO should work. However, we tested only with Open MPI <http://www.open-mpi.org/>. Without MPI, the distributed tools (xxx2lts-mpi, ltsmin-mpi) will not be built.

AsciiDoc

Download AsciiDoc (>= 8) from <http://www.methods.co.nz/asciidoc/>. We tested with asciidoc-8.2.7. Without asciidoc, documentation cannot be rebuilt. For convenience, release tarballs are shipping with pre-built man pages and HTML documentation.

xmlto

Download xmlto from <http://cyberelk.net/tim/software/xmlto/>. We tested with xmlto-0.0.18. Without xmlto, man pages cannot be rebuilt.

Doxygen

Download Doxygen from <http://www.doxygen.org/>. We tested with doxygen-1.5.5. Without doxygen, internal source code documentation cannot be generated.

MacOS X

For cross-compilation builds on MacOS X, the Apple Developer SDKs must be installed. They are available from Apple <http://developer.apple.com/tools/download/>, or from the MacOS X installation CDs.

Building from a Git Repository

Before building the software as described above, the following commands have to be executed in the top-level source directory:

# Rebuid autotools support
$ git submodule update --init
$ ./ltsminreconf

Dependencies

Building from another source than a release tarball requires some extra tools to be installed:

GNU automake

Download automake (>= 1.10) from <http://www.gnu.org/software/automake/>. We tested with automake-1.10.

GNU autoconf

Download autoconf (>= 2.60) from <http://www.gnu.org/software/autoconf/>. We tested with autoconf-2.61.

GNU libtool

Download libtool (>= 1.5.26) from <http://www.gnu.org/software/libtool/>. We tested with libtool-1.5.26.

AsciiDoc

See above. Note that AsciiDoc is a required dependency unless building from source tarballs.

xmlto

See above. Note that xmlto is a required dependency unless building from source tarballs.
