Well, I have done what you<br>
suggested, but still the program does not find the proper native<br>
library, in this case: "libvtkCommonCoreJava.so".<br>
<br>
This library is placed at "/usr/local/natives-Linux-x86_64", and it is<br>
also packed into the jar file "vtk-6.1-natives-Linux-x86_64.jar". The<br>
environment variable $LD_LIBRARY_PATH is set to point to that directory<br>
(as you suggested). Moreover, I have specify those dependencies in my<br>
Eclipse IDE as well. You can check all these evidences attached to this<br>
email as small screenshots.<br>
<br>
This is the piece of code that is generating the link error. The linker<br>
stops when processing the statement:<br>
<br>
System.loadLibrary("libvtkCommonCoreJava");<br>
<br>
--------------------<br>
import vtk.*;<br>
public class Cone {<br>
<br>
// In the static constructor we load in the native code.<br>
// The libraries must be in your path to work.<br>
static {<br>
<br>
// System.loadLibrary("vtkCommonJava");<br>
// System.loadLibrary("vtkFilteringJava");<br>
// System.loadLibrary("vtkIOJava");<br>
// System.loadLibrary("vtkImagingJava");<br>
// System.loadLibrary("vtkGraphicsJava");<br>
// System.loadLibrary("vtkRenderingJava");<br>
<br>
System.loadLibrary("libvtkCommonCoreJava");<br>
System.loadLibrary("libvtkFiltersCoreJava");<br>
System.loadLibrary("libvtkIOCoreJava");<br>
System.loadLibrary("libvtkImagingCoreJava");<br>
System.loadLibrary("libvtkRenderingCoreJava");<br>
}<br>
...<br>
}// End of the class: Cone<br>
<br>
Failing to run such a simple example of this library it's a bit<br>
frustrating for me. I'm looking forward to overcome this issue just to<br>
start learning this attractive visualization library.<br>
<br>
Thanks in advance.<br>
