JNIHelper

JNIHelper is a helper library which gives you more interaction possibilities between your java application and the system the application is running on.

What is the Java Native Interface?

see Wikipedia

The Java Native Interface (JNI) is a foreign function interface programming framework that enables Java code running in a Java virtual machine (JVM) to call and be called by native applications (programs specific to a hardware and operating system platform) and libraries written in other languages such as C, C++ and assembly.

What targets are supported by this library?

• the library itself is compatible with Windows and Linux
• the main target of this project are console applications
  • some functions should work without problems in graphical applications
• this library only supports platform specific native environments
  • this means, for example, that applications like Mintty are not supported

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites (Windows)

• Git
• JDK (Java SDK)
• MinGW (per example this distro)
• Microsoft Visual Studio 2017 or newer with the C++ workload
  • you only need MinGW or Visual Studio to build this project

Prerequisites (Linux)

• Git
• JDK (Java SDK)
• gcc, g++ and clang
• ncurses development package (per example libncurses-dev or ncurses-devel)
• PortAudio development package (per example portaudio-devel)

A note about installing PortAudio on Ubuntu and Debian

Installing portaudio19-dev downgrades the JACK Audio Connection Kit package from jackd2 to jackd1. To prevent this behavior, you must install the libjack-jackd2-dev package before installing portaudio19-dev. This fulfills the dependencies of the PortAudio development package without having to downgrade jackd2.

Setting up your system

• check if the JAVA_HOME environment variable points to the root dir of the JDK installation
• check if the javac command can be executed in your terminal app
• check if you can run the installed compiler in your terminal app (g++ on Windows, clang++ on Linux)
  • if not add the bin folder to your path environment variable

How to start the project

• clone this repo
• navigate your terminal to the scripts folder
• open the build script for your operating system
