Gdal installation on Mac OS - eclipse

Question

I’m trying to work with Gdal Library and Java in a Mac OS. But I’m new on Goal and I’m not able to make it works.
Also, I’m working with Maven. So I added this dependency on pom.xml
<dependency>
<groupId>org.gdal</groupId>
<artifactId>gdal</artifactId>
<version>2.1.0</version>
</dependency>
In order to test it on Eclipse I create a simple class like below:
import org.gdal.gdal.gdal;
import org.gdal.gdalconst.gdalconstConstants;
import org.gdal.ogr.ogr;
public class test {
public static void main(String[] args) {
gdal.AllRegister();
}
}
When I execute I’m facing with the following error:
Native library load failed.
java.lang.UnsatisfiedLinkError: no ogrjni in java.library.path
I tried to fix it all day without success. I just wanna know a simple way to execute Gdal into Eclipse.
PS: I can run Gdal successfully on terminal

Answer 1

You need to set the java.library.path system property when you run java. It must point to the directory containing the gdal shared libraries. I've also found that you may need to set the DYLD_LIBRARY_PATH or DYLD_FALLBACK_LIBRARY_PATH environment variable as well.
I have gdal installed via homebrew and here is what I do:
export DYLD_FALLBACK_LIBRARY_PATH=/usr/local/opt/gdal/lib
java -Djava.library.path=/usr/local/opt/gdal/lib -cp gdal.jar ...

GDAL installation
Install arguments
Make sure you have installed gdal with java and swig-java arguments.
brew install gdal --with-java --with-swig-java
ps: remove your current gdal installation before run the command above.
You may need some additional arguments. Check all arguments using
brew info gdal
Also, you can check the arguments available below.
--with-armadillo
Build with Armadillo accelerated TPS transforms.
--with-complete
Use additional Homebrew libraries to provide more drivers.
--with-java
Build with java support
--with-libkml
Build with Google's libkml driver (requires libkml --HEAD or >= 1.3)
--with-mdb
Build with Access MDB driver (requires Java 1.6+ JDK/JRE, from Apple or Oracle).
--with-mysql
Build with mysql support
--with-opencl
Build with OpenCL acceleration.
--with-postgresql
Build with postgresql support
--with-python3
Build with python3 support
--with-swig-java
Build the swig java bindings
--with-unsupported
Allow configure to drag in any library it can find. Invoke this at your own risk.
--without-python
Build without python2 support
--HEAD
Install HEAD version
Check gdal required dependencies
Check if you have installed all dependencies required by gdal. Use
brew info gdal
to see all dependencies and if you have them installed.
==> Dependencies
Required: libpng ✔, jpeg ✔, giflib ✔, libtiff ✔, libgeotiff ✔, proj ✔, geos ✔, json-c ✔, libxml2 ✔, pcre ✔, sqlite ✔, freexl ✔, libspatialite ✔
Optional: postgresql ✘, mysql ✔, armadillo ✔
==> Requirements
Build: java >= 1.7 ✔, fortran ✔, git ✔
Optional: java >= 1.7 ✔, python3 ✔
Maven configuration
If you're using maven on your project, you need to add gdal dependency in pom.xml.
<dependency>
<groupId>org.gdal</groupId>
<artifactId>gdal</artifactId>
<version>1.11.1</version>
</dependency>
Environment variable
You have to add environment variable in Eclipse, like jdeolive said.
Run > Run Configurations
then select your application in the left and go to Environment tab.
Add DYLD_LIBRARY_PATH and DYLD_FALLBACK_LIBRARY_PATH pointing to /usr/local/opt/gdal/lib.
That's how I installed gdal and it's working perfectly on macOS 10.12.6.
