LibPoly is a C library for manipulating polynomials. The target applications are symbolic reasoning engines, such as SMT solvers, that need to reason about polynomial constraints. It is research software under development, so the features and the API might change rapidly.
To compile on an Ubuntu machine you can install the prerequisites with
sudo apt-get install gcc cmake make libgmp-dev python2.7-dev python-sympy
To compile on a Mac you can install the prerequisites with
brew install gmp cmake python
sudo easy_install pip
pip install sympy
Python (and sympy) is not necessary and is used for testing the library through the Python bindings (these are also useful for playing with the library).
To compile and install perform
cd build
cmake .. -DCMAKE_BUILD_TYPE=$type -DCMAKE_INSTALL_PREFIX=$prefix
make
make install
The $type above is should be either "Debug" or "Release", and $prefix is the
target directory where the library will be installed. The prefix can be
omitted, in which case the library will be installed in the default system
location (such as /usr/local).
If the tests are enabled, you can do a sanity check of the library by doing a
make check.
The most up-to-date build instructions can be seen by looking at our CI
build script .github/workflows/ci.yml.
CMake will pick up the default python available in your shell. If you'd like to
force a different version you can use the Python_ADDITIONAL_VERSIONS variable.
For example, to use Python3 you can configure the project with
cmake .. -DPython_ADDITIONAL_VERSIONS=3
On some platforms (i.e. Mac) cmake picks different python installations for the headers and library. If this happens, you might try:
cmake .. -DCMAKE_BUILD_TYPE=$type -DPYTHON_LIBRARY=$pythonlibrary -DPYTHON_INCLUDE_DIR=$pythonheaderfiledirFor example:
cmake .. -DCMAKE_BUILD_TYPE=Release -DPYTHON_LIBRARY=/opt/homebrew/Cellar/python@3.9/3.9.4/Frameworks/Python.framework/Versions/3.9/lib/libpython3.9.dylib -DPYTHON_INCLUDE_DIR=/opt/homebrew/Cellar/python@3.9/3.9.4/Frameworks/Python.framework/Versions/3.9/include/python3.9/
Currently you can install the libpoly library (without python support) either using Homebrew or Aptitude.
Installing on Darwin using homebrew can be achieved via:
brew install SRI-CSL/sri-csl/libpoly
To install libpoly on Ubuntu or Debian, do the following:
sudo add-apt-repository ppa:sri-csl/formal-methods
sudo apt-get update
sudo apt-get install libpoly-dev
