[Gvsig_english] Starting the project collaboration

Thu May 6 13:18:01 CEST 2010

Just a few thoughts regarding Eclipse, Java and Ubuntu 10.04:

1. The Eclipse editor crashes randomly on Lucid Lynx.
For a temporary fix, export GRE_HOME to a bogus directory
before running Eclipse:

export GRE_HOME=/tmp

(this will probably be fixed with the first XUL Runner update)

2. Make sure to use a 32 bit JVM for developing with Eclipse.
Currently, the native libraries for raster support are all
32 bits and you cannot run 32 bit JNI bindings from a 64 bit JVM.

Have a good start into your project!

Ben

Cool, I'll add you to the project ASAP

Well this kind of conversation is getting technically more specific so
I'm adding César to it in order to let him correct me if I'm wrong.

Anyway, as I told you, from now I would prefer to have this kind of
support on the mailing list, it can be helpful for other developers.

Your life will be easier :-)

The building of gvSIG is documented mainly for Eclipse, but as we've
adopted Maven, it can also be done on your console using mvn CLI tool.

I recommend you strongly to use Eclipse.

Yes, in fact a working version of maven binaries is on the SVN so you
don't need to install it

Well 10.04 is pretty new, so I can't confirm you won't have any issue
working on it. BTW, everyone here uses Linux (mainly Ubuntu or
Kubuntu) to develop, but many others developers work also on Windows
XP. Two questions:

* On the ML are arising problems with the graphics card and 3D effects.
* The main problem could be with native libraries, I mean, gvSIG
native libraries could not be compatible with your system.

Try to install a regular gvSIG version and see if gvSIG is working.

Probably Benjamin has more info about this topic.

Perfect, setting for the first time the gvSIG 2.0 development
environment can be trickier, but if you are able to understand the
development documentation, follow the instructions.

http://www.gvsig.org/web/projects/gvsig-desktop/docs/devel/gvsig-devel-guide

I know, at this moment only in Spanish, but I assume that for an
Italian reader it's more or less possible to understand them.

We'll translate the docs into English, but as gvSIG libraries are in
development is a huge effort that we won't get in until the docs are
more or less "stable".

All the new javadocs are in English, but for older code the javadocs
can be in Spanish. If you find any javadoc you don't understand we can
translate it. IMHO a non English javadoc should be treated as a bug,
but for legacy code we're going to have a ton of bugs :(

Please don't hesitate to ask any question about this point (or any
other). If you get in trouble, ask us.

We use skype for IM (I'm "xurxosanz"), but if you don't feel
comfortable with it, we can use the #gvsig channel. It's not an
officially adopted tool, but well, I like it and I try to be on the
#osgeo channels and #gvsig of freenode. You can even use a web interface

http://webchat.freenode.net/

I hope you'll have fun and you'll acquire a really valuable expertise.
