Hi, My motivation for making the JDK 1.6 work on DragonFly was to run OpenGrok.
OpenGrok is a really nice source code browser. Want to see the definition of a function or where it is used ? Just type its name in a search box and click on the results. It is initially the work of a Sun employee, and was heavily used with the OpenSolaris project. Home page: http://hub.opensolaris.org/bin/view/Project+opengrok/WebHome Unfortunately, OpenGrok is written in Java, and is not as easy to run as more traditional programs. I have compiled a few instructions based on what I did to get it to browse the DragonFly source tree: 0. Use DragonFly-2.10 I have had some reports Java crashes on DragonFly 2.11 at the moment. 2.11 is under heavy development and this is not so surprising, but I better say it loud and clear before someone loses too much time trying 1. build lang/kaffe with gcc-4.1 and install it cd /usr/pkgsrc/lang/kaffe CCVER=gcc41 bmake install lang/kaffe is miscompiled by gcc-4.4 and cannot bootstrap the needed JDKs 2. install wip/jdk16 pkgsrc-wip is an additional set of packages which are not in pkgsrc. Get a tarball here and extract it in your pkgsrc tree: http://pkgsrc-wip.sourceforge.net/ You'll then get a new wip/ subdirectory 3. Install Tomcat from www/apache-tomcat6 4. Download the OpenGrok binary tarball I used the 0.10 version available here: http://hub.opensolaris.org/bin/view/Project+opengrok/files Extract it somewhere safe, like in /usr/local 5. Edit the file named bin/OpenGrok Add this at the top: OPENGROK_TOMCAT_BASE=/usr/pkg/share/tomcat And change some other variables: OPENGROK_INSTANCE_BASE="/var/opengrok" SRC_ROOT="/usr/src" DATA_ROOT="/var/tmp/opengrok_data" EXUBERANT_CTAGS="/usr/pkg/bin/exctags" JAVA_HOME="/usr/pkg/java/jdk-1.6.0" GIT="/usr/pkg/bin/git" 6. Deploy the web application in Tomcat ./bin/OpenGrok deploy 7. Create the index ./bin/OpenGrok index This will take a long time and eat much memory. A x86_64 system with 2GB memory kept swapping during the operation and the web interface was nearly unusable At this stage, OpenGrok is operational; it just won't find results for the parts of the code which are not yet indexed. 8. Point your web browser to http://the.opengrok.machine.address:8080/source That's all folks! -- Francois Tigeot
