BitFunnel

This is an experiment in text search/retrieval. It doesn't work (yet). We're making this available in the spirit of doing development out in the open, but nothing here has been cleaned up for public consumption. The documentation is non-existent and the code is in an incomplete state.

Dependencies

In order to build BitFunnel you will need CMake (2.8.11+), and a modern C++ compiler (gcc 5+, clang 3.5+, or VC 2015+). You can run CMake directly to generate the appropriate build setup for your platform. Alternately, we have some scripts that have the defaults that we use available.

*nix

For *nix platforms (including OS X),

./Configure_Make.sh
cd build-make
make
make test

Note that while these instructions are for a make build, it's also possible to build using ninja by changing the cmake command to create ninja files instead of Makefiles. These aren't listed in the instructions because ninja requires installing an extra dependency for some developers, but if you want to use ninja it's available via apt-get, brew, etc., and is susbtantially faster than make.

Ubuntu

If you're on Ubuntu 15+, you can install dependencies with:

sudo apt-get install clang cmake

On Ubuntu 14 and below, you'll need to install a newer version of CMake. To install a new-enough CMake, see this link. If you're using gcc, you'll also need to make sure you have gcc-5 (sudo apt-get install g++-5).

To override the default compiler, set the CXX and CC environment variables. For example, if you have clang-3.8 installed as clang-3.8 and are using bash:

export CXX="clang++-3.8"
export CC="clang-3.8"

OS X

Install XCode and then run the following command to install required packages using Homebrew (http://brew.sh/):

brew install cmake

BitFunnel can be built on OS X using either standard *nix makefiles or XCode. In order to generate and build makefiles, in the root BitFunnel directory run:

If you want to create an Xcode project instead of using Makefiles, run:

./Configure_XCode.sh

Windows

Install the following tools:

Visual Studio 2015 with C++ compiler
CMake (http://www.cmake.org/download/)

You can get the free version of Visual Studio here. Note that if you're installing Visual Studio for the first time and select the default install options, you won't get a C++ compiler. To force the install of the C++ compiler, you need to either create a new C++ project or open an existing C++ project.

In order to configure solution for Visual Studio 2015 run the following commands from the root BitFunnel directory:

.\Configure_MSVC.bat
