# Bdds

**YOU FIRST NEED TO INSTALL [cyclonedds](, tag: 0.9.0a1, ON THE HOST MACHINE,**

even if you only want to do crosscompile for Nerves.

If you are interested in the reason, read this [issue](

## Installation

If [available in Hex](, the package can be installed
by adding `bdds` to your list of dependencies in `mix.exs`:

def deps do
    {:bdds, "~> 0.0.1"}

Documentation can be generated with [ExDoc](
and published on [HexDocs]( Once published, the docs can
be found at [](

## Use with pure Elixir Project

Just compile with env, DDS_INSTALL_DIR(=/usr/local is default) like below

# If you installed cyclonedds to /usr/local, you don't need to specify DDS_INSTALL_DIR.
$ DDS_INSTALL_DIR=/usr mix deps.compile

## Use with Nerves Project

Just install bdds by adding to deps.
Then specify `MIX_TARGET`, make firmware like below

# This command cross compile cyclonedds and install it to Nerves firmware.
$ MIX_TARGET=rpi4 mix firmware
