Building gvSIG from SVN respository

by Jorge Sanz last modified 2012-09-10 16:09

Note

This document is obsolete. To build a gvSIG 2.0 use the Developers guide version 2.0.0.

If you want to build a gvSIG 1.9.0, gvSIG 1.10 or gvSIG 1.11, it is likely that this document will be valid with some minor exceptions. If you are going to follow it, use the following SVN reference instead of the ones contained into the document:

These tags are the ones related to the final version of gvSIG 1.9.0 and gvSIG 1.10.0, and the development builds of gvSIG 1.11.0.

Hint

The following guide to build gvSIG 1.9 from on Eclipse from the svn, provided by Eduardo Cristóbal Enríquez can also be consulted: CÓMO MONTAR gvSIG 1.9 EN ECLIPSE DESDE EL REPOSITORIO SVN

Introduction

This short article shows how to set up a development environment with Eclipse IDE 3.3 (Europa release) with the sources of the gvSIG SVN. In order to with a more or less stable version we will connect to a specific tag of the repository instead of the trunk. Later, if you feel brave, you can change to the trunk version and see what happens.

This article assumes that you:

  • Have experience with Eclipse
  • Have experience developing with gvSIG

If you have never worked with gvSIG as a developer, I encourage you to first work with version available on the Official Downloads section. When you get familiar with gvSIG's peculiarities then you are ready to start working directly with the SVN. You've been warned

Prepare your workspace

Create a new workspace with Eclipse and set the text file encoding to ISO-8859-1.

Now you should make sure that your active Java runtime is a SUN Java 1.5 SDK (update 12 or later) with Java JAI and Java JAI I/O in its classpath. The best way is to install JAI in that Java virtual machine but you can have it in an external location if you want.

Connecting to the SVN

For connecting to the gvSIG SVN repository I assume you're using the Subclipse client. Go to the SVN Repository Exploring perspective and add a new repository with the URL https://devel.gvsig.org/svn/gvsig-desktop

The gvSIG repository structure

Like any SVN repository, you will see the typical trunk/branches/tags structure. We will use the latest tag for the gvSIG 2.0 release prior to the data access refactoring. We're not going to work with the latest development version of gvSIG.

Note

Use tag v1_9_Build_1253 for try build gvSIG 1.9.0, v1_10_0_Build_1264 for gvSIG 1.10.0, or consult the last build of gvSIG 1.11.0 on https://devel.gvsig.org/svn/gvsig-desktop/tags/.

gvSIG 1211 tag

gvSIG 1211 tag

The tag folders (as in trunk or any branch of the project) are folders that store several (sometimes dozens) Eclipse projects. The main folders where we will get our projects are:

  • applications (gvSIG app on top of Andami)
  • binaries (.dll or .so)
  • extensions (all the extensions of Andami)
  • frameworks (Andami itself)
  • libraries (all the libraries used by extensions, Andami and appgvSIG)

Getting the source code for a minimalistic gvSIG

OK, now you have the source code repository configured and chosen the tag you're going to work with, it's time to download the eclipse project files. At this point I suggest to download and try to execute a really basic gvSIG build with the minimum set of features and then download more libraries and extensions.

So, first of all deactivate the automatic building property in order to first download all the code and then build it.

Deactivate Build Automatically

Deactivate Build Automatically

These are the 6 minimum projects you need to run gvSIG 1.9.0 (Consult the projects of gvSIG 1.10.0 and gvSIG 1.11.0):

_fwAndami:
The framework used by gvSIG for the MDI user interface
appgvSIG:
The application on top of Andami that adds the geo stuff
binaries:
The JNI and system libraries for your operating system, needed by several gvSIG components
libCorePlugin:
The skin for Andami that implements the GUI look and feel
libExceptions:
Common library of exceptions for gvSIG sources
libFMap:
Main library of gvSIG, it deals with geodata, rendering, etc.
gvSIG minimalistic set of projects

Downloading Andami

Downloading Andami

After downloading every project into your workspace you can switch on the Build Automatically setting. If everything works fine, you should not see any red crosses on your projects and you can start your first build.

NOTE: Sometimes Eclipse forgets some referenced libraries, so if you get missing classes or jars in a project, try to remove any jar of the referenced libraries set and add it again.

There is a main ant task in appgvSIG called install-all that runs every ant of the different gvSIG extensions and libraries in the correct order and places everything under Andami. You should also run the ant task of the binaries project to copy the proper native libraries into that folder.

Configure the run dialog

Now you can configure the run dialog to launch gvSIG. If you have a workspace for gvSIG 1.1.2 the configuration is the same and you can copy the arguments and environment variables to this new workspace.

The different screens of the New Java Application that should be configured are printed here for your convenience.

Environment variables

These screenshots show the configuration for a Windows box but Linux or Mac should be pretty similar.

With that configuration you should be able to run gvSIG, open shapefiles, use the new symbology support, and the basic gvSIG features. For a more complete gvSIG version with editing capabilities, WMS access, new icon design, raster access and projection features you will need to add more projects to your workspace.

A more powerful version of gvSIG

Now that you have a running gvSIG, let's upgrade your workspace a bit with more extensions and libraries.

A more complete gvSIG workspace

A more complete gvSIG workspace

Now you can repeat the process described above to get these extensions and libraries.

IMPORTANT: take care to rename libJCRS when you download it from the SVN repository as it tries to get another name, something like crsgdal.

IMPORTANT: you need to rebuild libUIComponent for extRasterTools-SE to compile because the Andami org.gvsig.ui.jar is outdated.

If you build any component or rebuild with the main appgvSIG ant, you should get a more powerful gvSIG running. From here, it's up to you to download more extensions. A sensible recommendation is to download the component you want to check and take a look at its dependencies. If you don't have them, download them from the repository.

Jump to the trunk

If you want to have the most recent code you can jump to the trunk of the repository. With Eclipse this is pretty easily done by selecting the Switch to another Branch/Tag... option and browsing to the trunk version of every project.

The near future

Maybe you've noticed that every project has a``pom.xml`` file. If you're familiar with Maven, you'll be happy to find that gvSIG is adopting this building and deploying framework. This will make it a lot easier to deploy the development environment and hopefully make this document unnecessary ;).

Another important issue to note is the refactoring that is being done at this moment by the gvSIG team. This means that in the near future libFMap's classic driver approach will be changed to a datastore one.

GNU GENERAL PUBLIC LICENSE

Version 2, June 1991

Copyright (C) 1989, 1991 Free Software Foundation, Inc., 51 Franklin Street, Fifth 
Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies of this license  
document, but changing it is not allowed.

Preamble

The licenses for most software are designed to take away your freedom to share and  
change it.  By contrast, the GNU General Public License is intended to guarantee 
your freedom to share and change free software--to make sure the software is free 
for all its users. This General Public License applies to most of the Free Software 
Foundation's software and to any other program whose authors commit to using it.  
(Some other Free Software Foundation software is covered by the GNU Lesser General 
Public License instead.)  You can apply it to your programs, too.


When we speak of free software, we are referring to freedom, not price.  Our 
General Public Licenses are designed to make sure that you have the freedom to 
distribute copies of free software (and charge for this service if you wish), that 
you receive source code or can get it if you want it, that you can change the 
software or use pieces of it in new free programs; and that you know you can do 
these things.

To protect your rights, we need to make restrictions that forbid anyone to deny you 
these rights or to ask you to surrender the rights. These restrictions translate to 
certain responsibilities for you if you distribute copies of the software, or if 
you modify it.

For example, if you distribute copies of such a program, whether gratis or for a 
fee, you must give the recipients all the rights that you have.  You must make sure 
that they, too, receive or can get the source code.  And you must show them these 
terms so they know their rights.

We protect your rights with two steps: (1) copyright the software, and (2) offer 
you this license which gives you legal permission to copy, distribute and/or modify 
the software.

Also, for each author's protection and ours, we want to make certain that everyone  
understands that there is no warranty for this free software.  If the software is 
modified by someone else and passed on, we want its recipients to know that what 
they have is not the original, so that any problems introduced by others will not 
reflect on the original authors' reputations.

Finally, any free program is threatened constantly by software patents.  We wish to 
avoid the danger that redistributors of a free program will individually obtain 
patent licenses, in effect making the program proprietary.  To prevent this, we 
have made it clear that any patent must be licensed for everyone's free use or not 
licensed at all.

The precise terms and conditions for copying, distribution and modification follow.

**GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION**

0. This License applies to any program or other work which contains a notice placed 
by the copyright holder saying it may be distributed under the terms of this 
General Public License.  The "Program", below, refers to any such program or work, 
and a "work based on the Program" means either the Program or any derivative work 
under copyright law: that is to say, a work containing the Program or a portion of 
it, either verbatim or with modifications and/or translated into another language.  
(Hereinafter, translation is included without limitation in the term 
"modification".)  Each licensee is addressed as "you".

Ac tivities other than copying, distribution and modification are not covered by 
this License; they are outside its scope.  The act of running the Program is not 
restricted, and the output from the Program is covered only if its contents 
constitute a work based on the Program (independent of having been made by running 
the Program).
Whether that is true depends on what the Program does.

1. You may copy and distribute verbatim copies of the Program's source code as you 
receive it, in any medium, provided that you conspicuously and appropriately 
publish on each copy an appropriate copyright notice and disclaimer of warranty; 
keep intact all the notices that refer to this License and to the absence of any 
warranty; and give any other recipients of the Program a copy of this License along 
with the Program.

You may charge a fee for the physical act of transferring a copy, and you may at 
your option offer warranty protection in exchange for a fee.

2. You may modify your copy or copies of the Program or any portion of it, thus 
forming a work based on the Program, and copy and distribute such modifications or 
work under the terms of Section 1 above, provided that you also meet all of these 
conditions:

   a. You must cause the modified files to carry prominent notices stating that you 
   changed the files and the date of any change.

   b. You must cause any work that you distribute or publish, that in whole or in 
   part contains or is derived from the Program or any part thereof, to be licensed 
   as a whole at no charge to all third parties under the terms of this License.

   c. If the modified program normally reads commands interactively when run, you 
   must cause it, when started running for such interactive use in the most 
   ordinary way, to print or display an announcement including an appropriate 
   copyright notice and a notice that there is no warranty (or else, saying that 
   you provide a warranty) and that users may redistribute the program under these 
   conditions, and telling the user how to view a copy of this    License.  
   (Exception: if the Program itself is interactive but does not normally print 
   such an announcement, your work based on the Program is not required to print an 
   announcement.)

These requirements apply to the modified work as a whole. If identifiable sections 
of that work are not derived from the Program, and can be reasonably considered 
independent and separate works in themselves, then this License, and its terms, do 
not apply to those sections when you distribute them as separate works.  But when 
you distribute the same sections as part of a whole which is a work based on the 
Program, the distribution of the whole must be on the terms of this License, whose 
permissions for other licensees extend to the entire whole, and thus to each and 
every part regardless of who wrote it.

Thus, it is not the intent of this section to claim rights or contest your rights 
to work written entirely by you; rather, the intent is to exercise the right to 
control the distribution of derivative or collective works based on the Program.

In addition, mere aggregation of another work not based on the Program with the 
Program (or with a work based on the Program) on a volume of a storage or 
distribution medium does not bring the other work under the scope of this License.

3. You may copy and distribute the Program (or a work based on it, under Section 2) 
in object code or executable form under the terms of Sections 1 and 2 above 
provided that you also do one of the following:

   a. Accompany it with the complete corresponding machine-readable source code, 
   which must be distributed under the terms of Sections 1 and 2 above on a medium 
   customarily used for software interchange; or

   b. Accompany it with a written offer, valid for at least three years, to give 
   any third party, for a charge no more than your cost of physically performing 
   source distribution, a complete machine-readable copy of the corresponding 
   source code, to be distributed under the terms of Sections 1 and 2 above on a 
   medium customarily used for software interchange; or

   c. Accompany it with the information you received as to the offer to distribute 
   corresponding source code.  (This alternative is allowed only for noncommercial 
   distribution and only if you received the program in object code or executable 
   form with such an offer, in accord with Subsection b above.)

The source code for a work means the preferred form of the work for making 
modifications to it.  For an executable work, complete source code means all the 
source code for all modules it contains, plus any associated interface definition 
files, plus the scripts used to control compilation and installation of the 
executable.  However, as a special exception, the source code distributed need not 
include anything that is normally distributed (in either source or binary form) 
with the major components (compiler, kernel, and so on) of the operating system on 
which the executable runs, unless that component itself accompanies the executable.

If distribution of executable or object code is made by offering access to copy 
from a designated place, then offering equivalent access to copy the source code 
from the same place counts as distribution of the source code, even though third 
parties are not compelled to copy the source along with the object code.

4. You may not copy, modify, sublicense, or distribute the Program except as 
expressly provided under this License.  Any attempt otherwise to copy, modify, 
sublicense or distribute the Program is void, and will automatically terminate your 
rights under this License.

However, parties who have received copies, or rights, from you under this License 
will not have their licenses terminated so long as such parties remain in full 
compliance.

5. You are not required to accept this License, since you have not signed it.  
However, nothing else grants you permission to modify or distribute the Program or 
its derivative works.  These actions are prohibited by law if you do not accept 
this License.  Therefore, by modifying or distributing the Program (or any work 
based on the Program), you indicate your acceptance of this License to do so, and 
all its terms and conditions for copying, distributing or modifying the Program or 
works based on it.

6. Each time you redistribute the Program (or any work based on the Program), the 
recipient automatically receives a license from the original licensor to copy,  
distribute or modify the Program subject to these terms and conditions.  You may 
not impose any further restrictions on the recipients' exercise of the rights 
granted herein.You are not responsible for enforcing compliance by third parties to 
this License.

7. If, as a consequence of a court judgment or allegation of patent infringement or 
for any other reason (not limited to patent issues), conditions are imposed on you 
(whether by court order, agreement or otherwise) that contradict the conditions of 
this License, they do not excuse you from the conditions of this License.  If you 
cannot distribute so as to satisfy simultaneously your obligations under this 
License and any other pertinent obligations, then as a consequence you may not 
distribute the Program at all.  For example, if a patent license would not permit 
royalty-free redistribution of the Program by all those who receive copies directly 
or indirectly through you, then the only way you could satisfy both it and this 
License would be to refrain entirely from distribution of the Program.

If any portion of this section is held invalid or unenforceable under any 
particular circumstance, the balance of the section is intended to apply and the 
section as a whole is intended to apply in other circumstances.

It is not the purpose of this section to induce you to infringe any patents or 
other property right claims or to contest validity of any such claims; this section 
has the sole purpose of protecting the integrity of the free software distribution 
system, which is implemented by public license practices.  Many people have made 
generous contributions to the wide range of software distributed through that 
system in reliance on consistent application of that system; it is up to the 
author/donor to decide if he or she is willing to distribute software through any 
other system and a licensee cannot impose that choice.

This section is intended to make thoroughly clear what is believed to be a 
consequence of the rest of this License.

8. If the distribution and/or use of the Program is restricted in certain countries 
either by patents or by copyrighted interfaces, the original copyright holder who 
places the Program under this License may add an explicit geographical distribution 
limitation excluding those countries, so that distribution is permitted only in or 
among countries not thus excluded.  In such case, this License incorporates the 
limitation as if written in the body of this License.

9. The Free Software Foundation may publish revised and/or new versions of the 
General Public License from time to time.  Such new versions will be similar in 
spirit to the present version, but may differ in detail to address new problems or 
concerns.

Each version is given a distinguishing version number. If the Program specifies a 
version number of this License which applies to it and "any later version", you 
have the option of following the terms and conditions either of that version or of 
any later version published by the Free Software Foundation. If the Program does 
not specify a version number of this License, you may choose any version ever 
published by the Free Software Foundation.

10. If you wish to incorporate parts of the Program into other free programs whose 
distribution conditions are different, write to the author to ask for permission.  
For software which is copyrighted by the Free Software Foundation, write to the 
Free Software Foundation; we sometimes make exceptions for this.  Our decision will 
be guided by the two goals of preserving the free status of all derivatives of our 
free software and of promoting the sharing and reuse of software generally.

**NO WARRANTY**

11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE 
PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED 
IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS"  
WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT 
LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR 
PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH 
YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY 
SERVICING, REPAIR OR CORRECTION.

12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY 
COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM 
AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, 
INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE 
PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED 
INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM 
TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN 
ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

END OF TERMS AND CONDITIONS

How to Apply These Terms to Your New Programs

If you develop a new program, and you want it to be of the greatest possible use to 
the public, the best way to achieve this is to make it free software which everyone 
can redistribute and change under these terms.

To do so, attach the following notices to the program.  It is safest to attach them 
to the start of each source file to most effectively convey the exclusion of 
warranty; and each file should have at least the "copyright" line and a pointer to 
where the full notice is found.

<one line to give the program's name and a brief idea of what it does.> Copyright 
(C) <year>  <name of author>

This program is free software; you can redistribute it and/or modify it under the 
terms of the GNU General Public License as published by the Free Software 
Foundation; either version 2 of the License, or (at your option) any later version.

This program is distributed in the hope that it will be useful, but WITHOUT ANY 
WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A 
PARTICULAR PURPOSE.  See the GNU General Public License for more details.

You should have received a copy of the GNU General Public License along with this 
program; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, 
Fifth Floor, Boston, MA 02110-1301 USA.

Also add information on how to contact you by electronic and paper mail.

If the program is interactive, make it output a short notice like this when it 
starts in an interactive mode:

Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with 
ABSOLUTELY NO WARRANTY;for details type show w. 

This is free software, and you are welcome to redistribute it under certain 
conditions; type show c for details.

The hypothetical commands show w and show c should show the appropriate parts of 
the General Public License.  Of course, the commands you use may be called 
something other than show w and show c; they could even be mouse-clicks or menu 
items--whatever suits your program.

You should also get your employer (if you work as a programmer) or your school, if 
any, to sign a "copyright disclaimer" for the program, if necessary.  Here is a 
sample; alter the names:

Yoyodyne, Inc., hereby disclaims all copyright interest in the program 
Gnomovision(which makes passes at compilers) written by James Hacker.

<signature of Ty Coon>, 1 April 1989

Ty Coon, President of Vice

This General Public License does not permit incorporating your program into 
proprietary programs. If your program is a subroutine library, you may consider it 
more useful to permit linking proprietary applications with the library.  If this 
is what you want to do, use the GNU Lesser General Public License instead of this 
License.
