Ant Error in Quickstart
Cerin
I just discovered the project, and was working through the Quickstart
(http://code.google.com/p/europa-pso/wiki/QuickStart). Everything was
going well, until I ran Ant, which gave me the error:

BUILD FAILED
/home/myuser/Light/build.xml:64: Java returned: 1
I'm running this in 64-bit Ubuntu 10.04. From the error, can I assume
the prebuilt Linux binaries are for 32-bit systems? Do I need to
recompile all the Europa code?

- you can use a 32 bit jvm, on 64bit macosx that's accomplished by
running java5, there is probably a similar option on Ubuntu (maybe
there is a command line option where you can force the jvm to run in
32 bit mode?).
- we recently got a 64bit linux machine to do builds on, you can grab
binaries from the trunk (bleeding edge, but relatively sae to use as
long as the build is green) from the autobuild page: http://babelfish.arc.nasa.gov/trac/europa/build

The file libantlr3c.so was included in the 2.5 release, but seems to
be missing in the 2.6 release. Is this correct? Where should I get
this library? I have antlr installed from Ubuntu's standard repo, but
I'm not sure if that can be used instead.

The expectation (changed from 2.5 to 2.6) is that you have ANTLR
installed locally. We have the source for the correct version checked
into our "ThirdParty" repository at
http://europa-pso.googlecode.com/svn/ThirdParty/trunk. There's an ANTLR
tarball in there. It's important, if you're using 64-bit Europa, that
you install 64-bit ANTLR libraries.

I didn't understand. Like I said, I do have 64 bit ANTLR installed locally.

It looks like all of Ubuntu's packages are the Java versions of
antlr3, and only provide jar files, not so files...
I tried compiling the version listed at
http://europa-pso.googlecode.com/svn/ThirdParty/trunk and received the
error

I'm not sure what dependencies I'm missing. From googling, I found
this might be caused by missing the development headers provided by
the libc6-dev package, but I have both Ubuntu's libc6 and libc6-dev
packages installed.

I discovered I also needed the gcc-multilib package...
With that, I can compile and install /usr/local/lib/libantlr3c.so.
However, building a Europa project with ant just generates another exception:
[java] Exception in thread "main" java.lang.UnsatisfiedLinkError:

I'm guessing the the default build for antlr3 is 32-bits.
Well, thanks for everyone's help. However, this is way too much hassle
just to demo Europa. I'll wait for the next official 64-bit release...

Chris
