This distribution includes the source of Yices, documentation, tests, and examples.

Yices 2 is developed by Bruno Dutertre, Dejan Jovanovic, and Ian Mason at the Computer Science Laboratory, SRI International. To contact us, or to get more information about Yices, please visit our website.

To build Yices from the source, you need:

• GCC version 4.0.x or newer (or clang 3.0 or newer)
• gperf version 3.0 or newer
• the GMP library version 4.1 or newer

• other standard tools: make (gnumake is required), sed, etc.

To build the manual, you also need:

• a latex installation
• the latexmk tool

To build the on-line documentation, you need to install the Sphinx python pacakge. The simplest method is:

sudo easy_install -U Sphinx

Sphinx 1.3.x or better is needed.

Do this:

autoconf
./configure
make
sudo make install

This will install binaries and libraries in /usr/local/. You can change the installation location by giving option --prefix=... to the ./configure script.

For more explanations, please check doc/COMPILING.

Yices supports non-linear real and integer arithmetic, but this is not enabled by default. If you want non-linear arithmetic, follow these instructions:

1. Install SRI's library for polynomial manipulation. It's available on github (https://github.com/SRI-CSL/libpoly).

2. After you've installed libpoly, add option --enable-mcsat to the cofigure command. In details, type this in the toplevel Yices directory:

autoconf
./configure --enable-mcsat
make
sudo make install

3 You may need to provide LDFLAGS/CPPFLAGS if ./configure fails to find the libpoly library. Other options may be useful too. Try ./configure --help to see what's there.

We recommend compiling using Cygwin. If you want a version that works natively on Windows (i.e., does not depend on the Cygwin DLLs), you can compile from Cygwin using the MinGW cross-compilers. This is explained in doc/COMPILING.

To build the manual from the source, type

make doc

This will build ./doc/manual/manual.pdf.

Other documentation is in the ./doc directory:

• doc/COMPILING explains the compilation process and options in detail.
• doc/NOTES gives an overview of the source code.
• doc/YICES-LANGUAGE explains the syntax of the Yices language, and describes commands, functions, and heuristic parameters.

To build the Sphinx documentation:

cd doc/sphinx
make html

This will build the documentation in build/html (within directory doc/sphinx). You can also do:

make epub

and you'll have the doc in build/epub/Yices.epub.

For further questions about Yices, please contact us via the Yices mailing lists [email protected]. This mailing list is moderated, but you do not need to register to post to it. You can register to this mailing list if you are interested in helping others.

Please submit bug reports through GitHub issues. Please include enough information in your bug report to enable us to reproduce and fix the problem. This is an example of a good report:

I am experiencing a segmentation fault from Yices. The following is a small test case that causes the crash. I am using Yices 2.4.1 on x86_64 statically linked against GMP on Ubuntu 12.04.

This is an example of a poor bug report:

I have just downloaded Yices. After I compile my code and link it with Yices, there is a segmentation fault when I run the executable. Can you help?

Please try to include answers to the following questions:

• Which version of Yices are you using?
• On which hardware and OS?
• How can we reproduce the bug? If possible, include an input file or program fragment.
