I have read the FAQ for UnsatisfiedLinkErrors but my problem was not solved. Here is the console output;

/home/alex/AMD-APP-SDK-v2.4-lnx64/lib/x86_64/
Obtaining platform...
Error while loading native library "JOCL-linux-x86_64" with base name "JOCL"

The first line outputs java.library.path and it is correct but the error still says “libOpenCL.so.1” does not exist.

Hello

A similar message has been reported in this thread. Although it is not perfectly clear what was the reason there, it seemed to be resolved after I asked which OpenCL implementation the user had installed - so maybe asking this question will help here as well…? :wink:

Hello

OK, I searched the forum again since this error message seemed somehow familiar, and indeed, the problem already occurred in this thread (and in a similar form form JCuda). It seems that a symbolic link has to be created to the respective file, so that the file can be found.

BTW: Did you set up your LD_LIBRARY_PATH and the other environment variables, as described in the AMD_APP_SDK_Installation_Notes (PDF File) ?

In doubt, I’ll ask the contributor of the binaries if he has an idea what might be wrong there.
