Overview ======== Spot is a model-checking library developed collaboratively by LRDE and LIP6. It provides algorithms and data structures to implement the automata-theoretic approach to LTL model checking. It is mainly meant to be used as a C++ library, but it also comes with a few handy command-line utilities, and some Python bindings. Keeping in touch ================ If you have questions regarding Spot, a bug reports, please send them to . This is a public mailing list which you may subscribe to at https://www.lrde.epita.fr/mailman/listinfo/spot but you should feel free to post without subscribing. We also run an extremely low traffic list for announcements of new releases of Spot. You may subscribe to that list at https://www.lrde.epita.fr/mailman/listinfo/spot-announce Installation ============ Requirements ------------ Spot requires a C++11-compliant compiler. G++ 4.8 or later, as well as Clang++ 3.5 or later should work. Spot expects a complete installation of Python (version 3.2 or later). Especially, Python's headers files should be installed. If you don't have Python installed, and do NOT want to install it, you should run configure with the --disable-python option (see below). Optional third-party dependencies ---------------------------------- If the SAT-solver glucose is found on your system, it will be used by our test suite to test our SAT-based minimization algorithm. Spot used to distribute a modified version of LBTT (an LTL to Büchi test bench), mostly fixing errors reported by recent compilers. However Spot now distributes its own reimplementation of LBTT, called ltlcross, so the use of LBTT is completely optional. The last modified version of LBTT we used to distribute can now be found at http://spot.lip6.fr/dl/lbtt-1.2.1a.tar.gz If some lbtt binary is found on your system, it will be used in the test suite in addition to ltlcross. Building and installing ----------------------- Spot follows the traditional `./configure && make && make check && make install' process. People unfamiliar with the GNU Build System should read the file INSTALL for generic instructions. In addition to its usual options, ./configure will accept some flags specific to Spot: --disable-python Turn off the compilation of Python bindings. These bindings offers a convenient interface with used in an IPython notebook, and are also used to build the CGI script that translates LTL formulae on-line. You may safely disable these, especially if you do not have a working Python 3.2+ installation or if you are attempting some cross-compilation. --enable-devel Enable debugging symbols, turn off aggressive optimizations, and turn on assertions. This option is effective by default in development versions (version numbers ending with a letter). It is equivalent to --enable-debug --enable-warnings --enable-assert --enable-optimizations=-O --disable-devel Disable development options. This is the case by default in releases (version numbers NOT ending with a letter). It is equivalent to --disable-debug --disable-warnings --disable-assert --enable-optimizations Here are the meaning of the fine-tuning options, in case --enable/disable-devel is not enough. --disable-assert --enable-assert Control assertion checking. --disable-warnings --enable-warnings Whether warnings should be output. Note that during development we consider warnings to be errors. --disable-debug --enable-debug Whether to compile extra debugging code. --enable-optimizations --enable-optimizations=FLAGS --disable-optimizations Whether the compilation should be optimized. When FLAGS are given, use these as optimization flags. Otherwise, pick working flags from a built-in list. Documentation ============= Some documentation can be found in the doc/ directory. - doc/spot.html/ contains documentation for the C++ library. - doc/tl/tl.pdf contains documentation about the various temporal logic operators supported by Spot "make install" will install man pages for command-line tools. (These man pages can also be found in the src/bin/man/ subdirectory of the source tree.)
