This project is currently in it's infancy and there will be quite a few issues to work through.
Currently the example creates an arrayfire array structure and runs the code from helloworld except indexing operations.
Edit build.conf to modify the build flags. The structure is a simple JSON blob. Currently Rust does not allow key:value pairs to be passed from the CLI. To use an existing arrayfire installation modify the first three JSON values.
To build arrayfire:
git submodule update --init --recursive cargo build
To run hello world example:

You might see something along the lines of :
dyld: Library not loaded: @rpath/libafopencl.3.dylib
This is related to this Rust issue A workaround for now is to add the location of libaf*.dylib to your LD_LIBRARY_PATH.
