Running the tests

In order to run the tests, you will need to have the grpcio, gevent, and grpcio-tools python packages installed. You can install them using pip. It is recommended that you use a python virtualenv to do this.

$ virtualenv path/to/virtualenv # to create a virtualenv
$ . path/to/virtual/env/bin/activate # to use an existing virtualenv
$ pip install grpcio-tools gevent
$ pip install grpcio # Need to install grpcio-tools first to avoid a versioning problem

Building GRPC

In order to compile this project, and anything which depends on it, you will need a working installation of the GRPC C core libraries. This library currently uses the 0.14 version range, so checkout an appropriate revision of the repository, and install as follows:

git clone https://github.com/grpc/grpc.git
git checkout 2b223977c13975648bac2f422363e1ebf83506ce
cd grpc
git submodule update --init
make
sudo make install

Alternatively, using Nix, pass the following expression to nix-build and point Stack to the build products in the Nix store:

let pkgs = import <nixpkgs> {};
in  pkgs.stdenv.mkDerivation rec
    {   name = "grpc";
        src = pkgs.fetchgit
        { url    = "https://github.com/grpc/grpc.git";
          rev    = "2b223977c13975648bac2f422363e1ebf83506ce";
          sha256 = "0arxjdczgj6rbg14f6x24863mrz0xgpakmdfg54zp0xp7h2pghm6";
        };
        preInstall = "export prefix";
        buildInputs =
        [   pkgs.darwin.cctools
            pkgs.autoconf
            pkgs.automake
            pkgs.libtool
            pkgs.which
            pkgs.zlib

            pkgs.openssl
        ];
    }
