To configure, compile and install iProver Modulo, use the following commands:
./configure [options]
make
make install
The following options are actually used by the configure script :
--prefix=PREFIX install files in PREFIX [default /usr/local]
--with-externdir=DIR installation directory of external programs
ocaml and e-prover are installed here
usefull if one does not want to overwrite existing
installations
[default ${prefix}/share/iprovermodulo/]
--with-runningpath=DIR execution path
path to eprover during execution
[default ${externdir}/bin]
--help print some help
Note that values passed to --datadir or --datarootdir options are not taken
into account.
You may need superuser rights to perform the installation.
Recommended usage of ./configure:
./configure --prefix=$HOME/tmp/ --with-externdir=$HOME/tmp --with-runningpath=$HOME/tmp/bin
For compiling, iProver modulo needs a C compiler. A version of the OCaml compiler is included in this package, it is installed with the prover and is needed at runtime to compile rewriting rules. Similarly, a version of eprover is included.
At runtime, iProver modulo needs eprover to transform clauses into CNF
(only version 1.4 was tested, but others should work as well), and
ocamlopt.opt to compile rewrite rules.
iProverModulo can be launched using the following command, where %s
has to be replaced by the problem file name and %d by the time limit:
iprover_modulo_launcher.sh %s %d
This executable calls the programs autotheo and iprover_moduloopt, which themselves call eprover and ocamlopt.opt. The PATH is modified to access the executables installed with the prover.
Solutions are given following the SZS ontology. For instance
% SZS status Theorem
or
% SZS status GaveUp
When a proof is given, it is enclosed within the following delimiters:
% SZS output start CNFRefutation
% Axioms transformation by autotheo
[...]
%-------------------------------------------------------------
% Dedukti proof by iprover
[...]
% SZS output end CNFRefutation
First, a proof of the transformation of the axioms into rewriting rules, and of the transformation of other formules into clausal normal form, is given in TSTP format.
Second, the proof found by iProverModulo is given in Dedukti's format.
Options:
--dedukti_out_proof <bool>
Outputs the proof in dedukti format, if it is found by resolution
--dedukti_prefix <string>
Prefix of the files containing the dedukti proof (default: printed on s
tandard output)
Output in <string>_sig.dk and <string>_prf.dk
--dedukti_tempfile <string>
Unique temporary file containing the dedukti proof (default: printed on
standard output)
