Failed to load aparapi

diPDew opened this issue 10 years ago · comments

I downloaded the latest code and imported the project as a Maven project into Eclipse. When I run JUnit test for AETest on my MacBook Pro (with OS X 10.9.2, i5 and Intel Iris 1024 MB), I got the following error:

TRAINING testAEBackpropagation...
Check your environment. Failed to load aparapi native library aparapi_x86_64 or possibly failed to locate opencl native library (opencl.dll/opencl.so). Ensure that both are in your PATH (windows) or in LD_LIBRARY_PATH (linux).

I cannot figure out this problem... May I know someone has ever experienced the same problem? Really need some help here. Thanks!

I think you have to point in the -Djava.library.path JVM variable the
location on your machine of the aparapi dylib. That is, download from the
aparapi site the correct version of the shared library for your Os and then
open the Eclipse launch configuration for the AETest and put
-Djava.library.path=<path-to-libaparapi_x86_64.dylib> into Arguments->VM
Arguments.

I hope it will resolve your problem :)
