Re: Pig compile error

Fri, 13 Feb 2009 06:50:32 -0800

I don't think you are compiling on 1.6. Those are all errors you see when trying to compile when using 1.5. The IOException(String, Throwable) is in 1.6 and not 1.5, and @Override semantics changed slightly. You may have the right version of java but the wrong version of javac. I see you're building on the mac. On my mac before I build I set JAVA_HOME to JAVA_HOME=/System/Library/Frameworks/ JavaVM.framework/Versions/1.6/Home 

This assures that I get the right version of javac.

You need jdk 1.6. Maybe that will help ?
