There are several ways to install PySAT. At this point, either way
assumes you are using a POSIX-compliant operating system with GNU
patch installed and available
from the command line. Installation also relies on a C/C++ compiler
supporting C++11, e.g. GCC or
Clang, as well as the
package. Finally, in order to compile
"C extensions" included as modules, the installer requires the headers
of Python and zlib.
Both can be installed using the standard package repositories.
Note that although version 0.1.5.dev1 of PySAT brings Microsoft Windows support, the toolkit was not extensively tested on this system. If you find out that something is broken on Windows, please, let us know. Your input is important.
Also note that using Clang is preferred on MacOS as there may be an
issue with GCC being unaware of the command-line option
--stdlib=libc++. Clang is available on MacOS by default. To enforce
the installer to use it, you need to set the environment variable
/usr/bin/clang. For that, do
export CC=/usr/bin/clang if using
setenv CC /usr/bin/clang if using tsch. This is not needed
pip install python-sat[pblib,aiger]
We encourage you to install the optional dependencies pblib and aiger, as shown in the previous command. However, if it cannot be done (e.g. if their installation fails), you can install PySAT with the functionality of aiger and pblib disabled:
pip install python-sat
Once installed from PyPI, the toolkit at a later stage can be updated in the following way:
pip install -U python-sat
Alternatively, one can clone the repository and execute the following command in the local copy:
python setup.py install
This will install the toolkit into the system's Python path. If another destination directory is preferred, it can be set by
python setup.py install --prefix=<where-to-install>
Both options (i.e. via
setup.py) are supposed to download and
compile all the supported SAT solvers as well as prepare the
installation of PySAT.
NOTE: For some shells, e.g. zsh, you may need to put the package names into single quotes, i.e. use
pip install 'python-sat[pblib,aiger]'. ↩︎
