Running OpenGrok on DragonFly
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:
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
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:
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:
Extract it somewhere safe, like in /usr/local
5. Edit the file named bin/OpenGrok
Add this at the top:
And change some other variables:
6. Deploy the web application in Tomcat
7. Create the 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!
