harmony-demo-1 for GSoC 2008
Hi everyone,
I'm a campus student who liked to know more about the harmony demo 1 project
you've listen on the wiki. I have some experience in Java but I don't have
any when it comes to game development.
I'd like to learn to get into game dev. And I could do that through making
FreeCol playable in Harmony. Is prior gaming dev knowledge required for
this? What do you recommend?

Tharindu

I had to make a soft link to libXext.so and libXtst.so .Had to manually
download the Xalan and cpptasks.

How about mentioning that InvocationTargetException is most likely to occur
due to this reason.

I don't think the build is that great either; i often run into issues.
However, if you can lay out the specific steps you took (are taking)
and what you're seeing, hopefully we can fix some of the issues.

It all depends on your system - I've never had to use it on my
moderate linux systems, but I always have to use it on my windows
machines.
As for the stack trace, this is just the way Ant and reflection works
- root exceptions get hidden in InvocationTargetExceptions. If Ant
were printing the cause of the exception, it'd be much more obvious.

Are you running the top-level (federated build)? Did you add the
"-Dauto.fetch=true" to the command line? This automates the dependency
download.

Hey I just want to say after toiling around the build for about 3 days I was
successfully able to build from the source. I had to manually download
files, soft link some libraries and had to be very patient to get it done
though.
I thank everyone who was patient enough to guide me through the build and
being tolerant of a newbie.
About ANT_OPTS="-Xthough.ms256m -Xmx512m". I noticed it, but its not
stressed as mandator, so I ignored it. And when that InvocationException
occured I thought it was a library problem. I would've expected a Heap out
of memory error. I had to consult you again when that occurred, if you
remember.
Also I had to run "ant fetch-depends" for common_resources to get log4cxx
from svn. It would be great if this also can be automated.
Thanks again to everyone who helped. I shall be on my way to run FreeCol
now.

Yeah, and it is written in step 3 of the getting started guide. I wonder
if it not clear enough there since Tharindu is not the first person to
raise it again.
I think it's because the Ant message is so confusing.

Hello,
Here [1] is an advise to export ANT_OPTS="-Xms256m -Xmx512m" to avoid
this exception. Please let me know if this helps for your case.

Hey,
I'm still failing to build. I sorted the issue xerces. That location gives a
corrupted version of the xerces zip. The mirror gives the proper zip.
I've created a jir and attached a patch (
https://issues.apache.org/jira/browse/HARMONY-5609). Then it asked for
ecj.jar in the ANT_HOME/lib which also I sorted out. I"m stuck at this
failure now.

Your previous download may have failed to get the entire file. Either
delete the partial download and try again, or manually download [1] that
file and put it in the depends/jars/xerces_2.9.1 directory.
[1] The build script tries to download it from
http://www.apache.org/dist/xml/xerces-j/Xerces-J-bin.2.9.1.zip
if you have a local mirror you can change the URL in
working_classlib/make/depends.xml

$ rm depends/jars/xerces_2.9.1/xerces.zip

I agree with Mark that is is likely a problem with the host JRE.

Forgive my rumbling: the further you are from the tested

Could you please take a look at [1]? Would invoking ant with
--noconfig option help?

1.7.0 works for me.
This sort of problem is usually caused by something being missing from
the $ANT_HOME/lib directory or using an old not java 5 VM. Make sure
you are running ant with a recent jre. Also, if you are using debian
(and probably ubuntu) make sure you have the ant-optional package
installed. If you are using something else, then someone else might
know the equivalent package.

Mark.

Re: harmony-demo-1 for GSoC 2008

A small problem occurred when I tried to build from the source.
fetch-classlib-libs:
BUILD FAILED
/home/mackie/harmony/build.xml:358: The following error occurred while
executing this line:
/home/mackie/harmony/build.xml:366: The following error occurred while

org.apache.tools.ant.util.regexp.Jdk14RegexpRegexp
How do I resolve this? I'm used to using maven2 rather than ant. So I'm a
bit unfamiliar on what to do. I used "ant -Dauto.fetch=true" as the
execution command.

Re: harmony-demo-1 for GSoC 2008

Hello Tharindu,
I don't think that the project requires any skills in game
development. The FreeCol seems to work on Sun. I have checked that Sun
shows the first menu which Harmony cannot. This means that most code
changes are suspected to be in Harmony. From the other side getting
familiar with FreeCol and AWT sources and architecture might be a good
start for a game developer.
As the first step I would recommend getting Harmony sources and
FreeCol jar from Internet, build the sources [1], try to launch
System.out.println("Hello World"), then launch FreeCol and reproduce
the error. If you succeed, you have a good chance to have enough
skills to succeed with the whole task as well.
BTW, you may have noticed that the other my task (harmony-gc-5) is to
improve Parrot efficiency by means of XFL garbage collector [2], in
other words, the efficiency of Lua scripts which are run by Parrot VM.
And Lua is used for scripting in many games such as World of Warcraft.

Hi Tharindu. Hopefully Alexei will respond (since he thought of this
project), but I expect you will need familiarity with graphics systems
more than gaming. The project is to enhance Harmony to work with the
existing game code rather than change the game itself.

I think it would be a good opportunity to see how existing games are
written and the operations that are used in the runtime. That will be a
basis for you to use the same operations for your own gaming ideas.
