Today I made my second official patch to OpenJDK. I forgot how to make the jtreg test and had to figure it out all over again, so here’s my quick and dirty guide for the future:

1. Build jtreg. I use the IcedTea one, because it’s there:

   make jtreg

2. Make a test root and copy your test into it:

   mkdir -p tests/tests
   touch tests/TEST.ROOT
   mv ~/Test6779290.java tests/tests
   

3. Run the tests:

   openjdk-ecj/control/build/linux-ppc/j2sdk-image/jre/bin/java -jar test/jtreg.jar -v1 -s tests

In other news it’s over a year since I started hacking on Zero. I was hoping to be able to announce a TCK-passing build before Christmas but that’s not going to happen. Oh well.

Apparently Fedora 10′s eclipse-ecj doesn’t have gcj-compiled libraries any more. Never mind:

mkdir /usr/lib/gcj/eclipse-ecj
aot-compile -c "-O3" /usr/lib/eclipse/dropins/jdt/plugins /usr/lib/gcj/eclipse-ecj
rebuild-gcj-db

Also, whilst I’m messing with my system, I’ve always had to do the following for ppc64 builds to work:

mkdir -p /usr/lib/jvm/java-gcj/jre/lib/ppc64/server
ln -s /usr/lib64/gcj-4.3.2/libjvm.so /usr/lib/jvm/java-gcj/jre/lib/ppc64/server

I never figured out how anyone else manages without this. Maybe nobody else is trying to build two platforms on the one box.
