Can't find /lib/libJOCL-linux-x86.so

I have a NVida graphic card and I would like to use it for serious computations. I downloaded a driver from NVida webside and installed JOCL bindings. I downloaded one of the demo programs and compiled it. The program however does not run because:

Trying to solve it I did the following:

• I am positive that "JOCL-0.1.4d.jar" file is properly added to classpath; /lib/libJOCL-linux-x86_64.so for sure is inside this jar

• I also extracted libJOCL-linux-x86_64.so form the jar and used a respective -Djava.library.path= command.

• The libJOCL-linux-x86_64.so library is also on my LD_LIBRARY_PATH

• I also run ldconfig in the proper directory to index this library

but the problem persists

According to the error message you're running this in a 32 bit VM, which would mean that you'd need the 32bit .so file (or switch to using a 64bit JVM).

Note that Java usually loads .so files from the java.library.path (and not necessarily from LD_LIBRARY_PATH).
