Random Graph Perfect Hashing with optional Lua bindings

You need c99, c++ compilers and POSIX-compatible make utility to build the library and the tests. Makefiles don't use any fancy stuff and there is no support for auto configuration.

Typing (cd lib && make) should work but it may produce unoptimised binaries. It's best to set optimisation flags in CFLAGS and CXXFLAGS variables. You may also want to pass -DUNALIGNED_READ when building on platforms with fast unaligned reads.

To build a shared library:

(cd lib && make CFLAGS='-O2 -g' CXXFLAGS='-O2 -g' all-c)

To build on OSX, you should pass DSO=dylib:

(cd lib && make CFLAGS='-O2 -g' CXXFLAGS='-O2 -g' DSO=dylib all-c)

To build the Lua module, you need pkg-config Lua package. XXX luarocks.

(cd lib && make CFLAGS='-O2 -g' CXXFLAGS='-O2 -g' all-lua)

The above command assumes that your Lua package is known to pkg-config as lua. You can specify an alternative name with LUAPKG=lua-5.3.

Lua versions 5.1, 5.2 and 5.3 are supported.
