Are you intrigued by the concept of Java and seek to build self-contained applications with a lightweight twist? If yes, you’re in for a treat. Avian, a lightweight Java Virtual Machine (JVM), offers the essential features of Java while focusing on a minimalistic architecture. Although the project is not currently under active development or support, it remains an excellent choice for those who want to explore JVM capabilities. Let’s dive into a comprehensive guide on how to build and install Avian across different operating systems.

Quick Start Guide

This guide provides examples of building Avian on various operating systems, ensuring compatibility with the x86_64 architecture. Remember to adjust the JAVA_HOME variable according to your JDK installation path. Always use forward slashes in your paths. Here’s how to go about it:

• On Linux:

  $ export JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64
  $ make
  $ buildlinux-x86_64avian -cp buildlinux-x86_64/test Hello

• On Mac OS X:

  $ export JAVA_HOME=$(/usr/libexec/java_home)
  $ make
  $ buildmacosx-x86_64avian -cp buildmacosx-x86_64/test Hello

• On Windows (Cygwin):

  $ git clone git@github.com:ReadyTalk/win64.git ../win64
  $ export JAVA_HOME=/cygdrive/c/Program\ Files/Java/jdk1.7.0_45
  $ make
  $ buildwindows-x86_64avian -cp buildwindows-x86_64/test Hello

• On FreeBSD:

  $ export JAVA_HOME=/usr/local/openjdk7
  $ gmake
  $ buildfreebsd-x86_64avian -cp buildfreebsd-x86_64/test Hello

Understanding the Build Process

Picture this: Building Avian is akin to assembling a Lego structure. Each command you execute corresponds to picking a new Lego piece and clicking it into place until your masterpiece is complete. Starting with the make command, you’re essentially telling the system that you want to initiate the building process. The export commands set the foundation by ensuring the necessary environment variables are in place, much like sorting your Lego pieces before beginning the assembly.

Installing Avian

Installing Avian is straightforward. Simply copy the executable to your desired directory:

$ cp build/$platform-$arch/avian ~/bin

Troubleshooting Tips

If you encounter issues during the installation or building process, consider the following:

• Double-check that you’re using the correct paths and are utilizing forward slashes.
• Ensure that you have the necessary build tools installed:
• GNU make version 3.80 or later
• GCC version 4.6 or later, or LLVM Clang 3.1 or later
• JDK 1.6 or later
• If building on Windows, verify that Cygwin is correctly set up.
