Clone Z3

Navigate to the Z3 Github repository to view the project.

Open a terminal on your computer and navigate to where you want to clone the Z3 repository (Ex: C:\Z3).

From that location, run:

git clone https://github.com/z3Prover/z3.git

Building Z3 on Windows using Visual Studio Command Prompt

Open Developer Command Prompt for VS 2019 through the start menu.

Navigate to the folder that you cloned the Z3 repository into (Ex: C:\Z3).

For 32-bit builds, run:

python scripts/mk_make.py

For a 64-bit build, run:

python scripts/mk_make.py -x

then run:

cd build
pip install z3-solver

You should now be able to open Visual Studio and run Z3 with its Python binding.

To test, you can run:

from x3 import *
x = Real('x')
y = Real('y)
s = Solver()
s.add(x + y > 5, x > 1, y > 1)
print(s.check())
print(s.model())

The last two lines should produce sat and [y = 4, x = 2].
