    Is this the example provided by NVIDIA? I have a problem in linking library and I'm not able to solve it. Are there other examples about the use of cuDNN?

    @Maria: yes, this is the example given by Nvidia. I got this while attending the Nvidia GTC 2015 workshops. Originally this was meant for Linux and I was able to get it working for Mac OSX. Let me know if you have questions. (@vivekv80)

    I tried import the example, but it doesn't run. I tried to import the example creating a "Makefile project with existing code" but when I compile I have a library error (libfreeimage.a produce a symbol(s) not found for architecture x86_64). 
    If i change the -lfreeimage in -lfreeimage-3.13.1 I can compile without errors but when I run the project I have the error: 
    dyld: Library not loaded: libfreeimage-3.13.1.dylib-x86_64
    Referenced from: mnistCUDNN path
    Reason: image not found
    Any idea on how can I solve this linking problem?

    @Maria: I installed FreeImage using macports into /opt/local and linked to it. Can you try that?
