[gdal-dev] Using Java bindings of GDAL library : UnsatisfiedLinkError

[Kedar Deshpande]

I am still getting the same exception. Even export env variable is not
working.
The entire exception I am getting is :

kdeshpan.desktop% java -classpath `pwd`/gdal.jar:`pwd`:`pwd`/apps
apps/TestClass
Native library load failed.
java.lang.UnsatisfiedLinkError:
/rhel5pdi/home/kdeshpan/gdal_java/swig/java/libogrjni.so:
/rhel5pdi/home/kdeshpan/gdal_java/swig/java/libogrjni.so: wrong ELF class:
ELFCLASS64 (Possible cause: architecture word width mismatch)
Exception in thread "main" java.lang.UnsatisfiedLinkError:
org.gdal.ogr.ogrJNI.RegisterAll()V
        at org.gdal.ogr.ogrJNI.RegisterAll(Native Method)
        at org.gdal.ogr.ogr.RegisterAll(ogr.java:110)
        at apps.TestClass.main(TestClass.java:9)

What am I missing? Can someone please let me know all the steps for using
this library with Java bindings.

Thanks,
Kedar
