This section explains how to install Yices, and how to compile and link your code with the Yices library.


Yices 2 can be downloaded at http://yices.csl.sri.com. You can either get a source distribution, or a binary distribution for Linux, Mac OS X, or Windows.

Installing from the Source

Compiling Yices from the source requires the GNU Multiple Precision library (GMP) and the gperf utility. Assuming you have both, then building and installing Yices is straightforward:

make -j
sudo make install

This installs the binaries in /usr/local/bin, the header files in /usr/local/include, and the library in /usr/local/lib. You can change the installation location by giving the option --prefix=<directory> to the configure script.

For a detailed explanation of the build process and options, check the file doc/COMPILING included in the distribution.

MCSAT and Nonlinear Arithmetic

Yices now includes a solver for nonlinear arithmetic based on the Model Constructing Satisfiability Calculus (MCSAT). This solver depends on an external library for manipulating polynomials. If you need nonlinear arithmetic and want to compile Yices from the source, you must install this library first. Get it from our GitHub repository and follow the build instructions there. Make sure to get the latest libpoly release (v0.1.3).

Once you have installed libpoly, you can compile Yices with MCSAT support as follows:

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

You may need to set CPPFLAGS and LDFLAGS if the libpoly library is not in a standard location.

Binary Distribution

The binary distributions contain pre-compiled binaries and libraries. These distributions are self-contained. The binaries and libraries are linked statically against GMP and libpoly. They include support for nonlinear arithmetic and MCSAT.

The binary distributions for Linux and Mac OS X include a shell script to install the binaries, headers, and library in /usr/local. You can run this script as follows:

sudo ./install-yices

If you want a different installation directory, type

./install-yices <directory>

(use sudo if necessary).

Headers and Compilation

The Yices API is defined in three header files:

  • yices.h declares all functions and constants
  • yices_types.h defines the types and data structures used in the API
  • yices_limits.h defines hard-coded limits

For a standard installation, these files are in directory /usr/local/include.

To use the API, you should add the following line to your code:

#include <yices.h>

and link with the Yices library using option -lyices.

Several functions in the API take GMP numbers (e.g., mpq_t or mpz_t) as arguments. To use these functions, make sure to include the GMP header before you include yices.h as in:

#include <gmp.h>
#include <yices.h>


Yices requires the C99 header stdint.h. This header may not be available on old versions of Microsoft’s Visual Studio. If it is missing, open-source versions of stdint.h can be downloaded at

A copy of the latter file is included in the Yices distributions (in etc/pstdint.h).

Minimal Example

Here is a minimal example:

#include <stdio.h>
#include <yices.h>

int main(void) {
   printf("Testing Yices %s (%s, %s)\n", yices_version,
           yices_build_arch, yices_build_mode);
   return 0;

Assuming that Yices is installed in the standard location, this example should compile with:

gcc minimal.c -o minimal -lyices

Other compilers than GCC can be used. If Yices is installed in a different location, give appropriate flags to the compilation command. For example:

gcc -I${HOME}/yices-2.3.1/include -L${HOME}/yices-2.3.1/lib \
   minimal.c -o minimal -lyices

Running the program should print something like this:

Testing Yices 2.3.1 (x86_64-unknown-linux-gnu, release)

You may need to play with environment variable LD_LIBRARY_PATH (or DYLD_LIBRARY_PATH on Mac OS X) if the runtime Yices library is not found.
