Minimal unsatisfiable core extractor for SMT

Requierments:

• Visual Studio 2015
• Python 3
• Z3 insalled (can be found at https://github.com/Z3Prover/z3)

Installation:

Windows

• Download z3 ver. 4.4.2 (if you do not have access to it, you can download our own precompiled version from https://drive.google.com/open?id=15IX6Jyvy-aqW0_oPGqo5YzcR0fow63I1)

• Best is to extract the z3 folder directly to c:\

• Open HSmtMuc.sln using Visual Studio 2017 or newer and build the project using x86 configuration

• If you chose earlier to put z3 in a folder other than c:\, then you need to change the path in several locations inside the project properties of hsmtmuc in order for it to compile. Specifically, in

  -- configuration properties / VC++ directories,

  -- C/C++ / General/ Additional Include Directories,

  -- Linker / Input / Additional dependencies.

Linux

• If z3 not built, follow the build instructions, using https://github.com/Z3Prover/z3#building-z3-using-make-and-gccclang
• Add "/build" directory to the PATH and LD_LIBRARY_PATH variables.
• Add "/scripts" directory to the PYTHONPATH variable.
• From the src folder, run make

Running:

• The argument list can be accessed using the -h or --help argument. For a basic run you just need the arguments "-file <input-file-name>".
• The ouput MUC appears in the input file's folder with an extension ".muc".
