"helloworld" with Maxine JVM on Mac

Last night, I listened to this nice podcast on Maxine JVM from Software Engineering Radio. Maxine is a Java Virtual Machine implemented in the Java programming language.

I wanted to try out Maxine on my MacBook Pro running Mac OS X 10.5.8. I followed these steps to try it out:

• Get the Maxine sources

  
      hg clone https://kenai.com/hg/maxine~maxine maxine
  
  

• Setup the environment

  
      export JAVA_HOME=/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home
      export JUNIT4_CP=<full-path-of junit-4.4.jar>
  
  

• Build Maxine

  
     cd $MAXINE_HOME/bin
     ./max build
     ./max image   
  
  

• Run the "helloworld"

  
      ./max helloworld
  
  

Wow! Maxine VM printed "Hello World!". Now, it is time to explore Maxine's inspector and other cool stuff ...
