Usage

After you the necessary pre-requisites, edit the following paramets

• Open Makefile and change AF_PATH to the right location

Linux

• To build the JNI Wrapper for ArrayFire use

  • make cuda to build using CUDA
  • make opencl to build using OpenCL

• To build the examples do one of the following from the examples directory

  • make cuda run to use build and run examples using CUDA
  • make opencl run to use build and run examples using OpenCL

Windows

• To build the JNI Wrapper for ArrayFire

  • Verify if the following macros are correctly defined in the file Makefile.Windows.
    • Ensure that VC_ROOT points to Visual-C (VC) installation path.
    • Ensure that WINSDK_X64 points to Windows SDK X64 library path.
  • Launch Developer command prompt for Visual Studio 2012.
