Basic Configuration Options - the configure utility

The following options are for compiling and installing a working version of the NTP distribution. In most cases, the build process is completely automatic. In some cases where memory space is at a premium, or the binaries are to be installed in a different place, it is possible to tailor the configuration to remove such features as reference clock driver support, debugging support, and so forth.

Configuration options are specified as arguments to the configure script. Following is a summary of the current options, as of the 4.0.99m version:

Usage: configure [options] [host]
