## Z3 API Bindings
Z3 exposes various language bindings for its API. Below are some notes on building
and/or installing these bindings when building Z3 with CMake.
### Java bindings
The CMake build uses the ``FindJava`` and ``FindJNI`` cmake modules to detect the
installation of Java. If CMake fails to find your installation of Java set the
``JAVA_HOME`` environment variable when invoking CMake so that it points at the
correct location. For example
```
JAVA_HOME=/usr/lib/jvm/default cmake -DBUILD_JAVA_BINDINGS=ON ../
```
Note that the built ``.jar`` file is named ``com.microsoft.z3-VERSION.jar``
where ``VERSION`` is the Z3 version. Under non Windows systems a
symbolic link named ``com.microsoft.z3.jar`` is provided. This symbolic
link is not created when building under Windows.
## Developer/packager notes ## Developer/packager notes
These notes are help developers and packagers of Z3. These notes are help developers and packagers of Z3.
