Installing from source
You can use these steps below to get watchman built. You will need autoconf, automake and libtool (or glibtool on OS X). You may optionally build watchman without pcre and python support (see configuration options below). For python support, you will need setuptools and may need to install a python-dev or python-devel package. To build the C++ client library you will need to install libfolly.

See below for some more information on options to configure your build.
