# Locate gdal

# This module defines

# GDAL_LIBRARY

# GDAL_FOUND, if false, do not try to link to gdal 

# GDAL_INCLUDE_DIR, where to find the headers

#

# $GDALDIR is an environment variable that would

# used in building gdal.

#

# Created by Eric Wing. I'm not a gdal user, but OpenSceneGraph uses it 

# for osgTerrain so I whipped this module together for completeness.

# I actually don't know the conventions or where files are typically

# placed in distros.

# Any real gdal users are encouraged to correct this (but please don't

# break the OS X framework stuff when doing so which is what usually seems 

# to happen).

# This makes the presumption that you are include gdal.h like

# #include "gdal.h"

ERROR!!

You have to define your gvSIG platform properties, 

by creating the file: ${user.home}/.gvsig.platform.properties

with the following content:

native_platform=linux

native_distribution=all

native_compiler=gcc4

native_arch=i386

native_libraryType=dynamic

export native_classifier=${native_platform}-${native_distribution}-${native_compiler}-${native_arch}-${native_libraryType}

Replace the fifth initial variables values with the ones appropiate 

to your platform.

If you use maven in the command line, you can use the previous file also

to define the MAVEN_OPTS environment variable, by adding to your 

.bash_rc file something like this:

if [ -f "${HOME}/.gvsig.platform.properties" ]

then

    . ${HOME}/.gvsig.platform.properties

    export MAVEN_OPTS="-Xmx256M -XX:MaxPermSize=64m -Dnative-classifier=${native_classifier}"

else

    export MAVEN_OPTS="-Xmx256M -XX:MaxPermSize=64m"

fi

It will work if you use the bash shell. In any other case or platform, you'll

have to define your MAVEN_OPTS environment variable and set the 

"native-classifier" parameter directly.

How to compile libjni-gdal

--------------------------

General Requirements

--------------------

Make sure you have a directory .m2 in your $HOME. In this directory there should be a file settings.xml. This step is only necessary if you have to deploy files.

<?xml version="1.0" encoding="UTF-8"?>

<settings xmlns="http://maven.apache.org/POM/4.0.0" 

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

                        http://maven.apache.org/xsd/settings-1.0.0.xsd">

    <servers>

        <server>

            <id>gvsig-repository</id>

            <username>[USERNAME]</username>

            <password>[PASSWORD]</password>

            <filePermissions>666</filePermissions>

	    <directoryPermissions>777</directoryPermissions>

        </server>

    </servers>

</settings>

Linux

-----

Installed programs

cmake (apt-get install cmake)

maven (minimum version 2.2.1. This version is available in build directory)

ant (apt-get install ant)

Open a system console and set variable JAVA_HOME with a right value.

ej: export JAVA_HOME=[Path_to_JDK]

Launch the command to compile:

mvn install -Dnative-arch=[ARCHITECTURE] -Dnative-distribution=[DISTRIBUTION] -Pjni-devel -Dmaven.test.skip -Dnative-classifier=[CLASSIFIER]

ARCHITECTURE = "X86_64", "i386", ...

DISTRIBUTION = "nt", "Ubuntu-9.10", "10.5", ...

CLASSIFIER = linux-Ubuntu-9.10-gcc4-X86_64-dynamic

Example:

mvn install -Dnative-arch="X86_64" -Dnative-distribution="Ubuntu-9.10" -Pjni-devel -Dmaven.test.skip -Dnative-classifier=linux-Ubuntu-9.10-gcc4-X86_64-dynamic

Windows

-------

Installed programs

Visual Studio 2005 (vs8)

cmake

maven (minimum version 2.2.1. This version is available in build directory)

ant

Make sure you have the right value in your JAVA_HOME variable

libjni-gdal needs a GDAL SDK to be compiled. This SDK is in the maven repository. The pom.xml contains

the version of GDAL. You should check the version.

<dependency>

  <groupId>org.gdal</groupId>

  <artifactId>gdal</artifactId>

  <version>1.7.1</version>

  <classifier>${native-classifier}</classifier>

  <type>tar.gz</type>

</dependency>

The binaries of this version will be downloaded from maven repository. 

http://gvsig-desktop.forge.osor.eu/downloads/pub/projects/gvSIG-desktop/maven-repository/

Launch the command to compile:

mvn install -Dnative-arch=[ARCHITECTURE] -Dnative-distribution=[DISTRIBUTION] -Pjni-devel -Dmaven.test.skip -Dnative-classifier=[CLASSIFIER]

ARCHITECTURE = "X86_64", "i386", ...

DISTRIBUTION = "nt", "Ubuntu-9.10", "10.5", ...

CLASSIFIER = win-nt-gcc4-vs8-i386-dynamic

Example:

mvn install -Dnative-arch="i386" -Dnative-distribution="win-nt" -Pjni-devel -Dmaven.test.skip -Dnative-classifier=win-nt-gcc4-vs8-i386-dynamic
