Arrayfire Rust Bindings

This project is a work in progress. You can find the basic documentation here(please be advised that we are in the process of updating it). If you find any bugs, please report them here. Currently the wrapper is ArrayFire 3.0 compliant.

Building & Running

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:

~/p/arrayfire_rust> cargo run --example helloworld
...
     running 1 test

Issues

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.
