Going through the build instructions on https://wiki.openjdk.java.net/display/MacOSXPort/Main I ran into a few things:
1. the build step doesn't tell you to chmod & run ./configure. This was easy to fix because make warned me that I needed to do it. It'd be nice if it were in the docs though. 2. The resulting build directories seem to have changed slightly. The wiki lists this as the java bin location: build/macosx-universal/j2sdk-image/bin/java but when I build, it ends up here: build/macosx-x86_64-normal-server-release/jdk/bin/java 3. There's a similar difference for the install instructions wiki: cp -R build/macosx-universal/j2sdk-bundle/jdk1.8.0.jdk ~/Library/Java/JavaVirtualMachines what I used: cp -R build/macosx-x86_64-normal-server-release/jdk ~/Library/Java/JavaVirtualMachines/jdk1.8.0-internal These issues were all pretty minor and easy to figure out myself, but I think it'd be really slick if they were updated. I'm amazed at how painless building openjdk is--I should have tried it years ago! -- -Nick Howard http://blog.baroquebobcat.com/
