Installing z3py

The Z3 Python API requires the following environment variables to be set up.

• The PATH or LD_LIBRARY_PATH variables needs to poin to the directory containing "libz3.dll" or "libz3.so"
• The PYTHONPATH environment variable needs to point to the directory that contains "z3/z3.py"

If you obtained the Z3 distribution as part of our binary release zip files, which you unzipped into a directory called "MYZ3", then follow these instructions to update the environment variables:
Windows:

set PATH=%PATH%;MYZ3\bin
set PYTHONPATH=MYZ3\bin\python

Linux:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:MYZ3/bin
export PYTHONPATH=MYZ3/bin/python

On Ubuntu, even if you have installed z3py through `apt install python-z3`, you still need to manually setup the paths as follows:

export LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu
export PYTHONPATH=/usr/lib/python2.7/dist-packages/z3
