Following are instructions to build and install the programs in this distribution.
Note that the automatic build process inspects the machine environment and tests for the presence of system header files and the contents of these files to determine if certain features are available. When one or more of these features are present, the code is compiled to use them; if not, no special code is compiled. However, even if the code is compiled to use these features, the code does a special test at run time to see if one or more are actually present and avoids using them if not present. In such cases a warning message is sent to the system log, but the daemon should still work properly.
Make sure that you have all necessary tools for building executables.
These tools include
cc/gcc, make, awk, sed, tr, sh, grep,
egrep and a few others. Not all of these tools exist in the
standard distribution of modern Unix versions (compilers are likely to
be an add-on product - consider using the
gnu tools and
gcc compiler in this case). For a successful build, all of
these tools should be accessible via the current path.
configure command to perform an automatic
configuration procedure. This procedure normally includes the debugging
code, which can be useful in diagnosing problems found in initial test,
and all reference clock drivers known to work with each machine and
operating system. Unless memory space is at a premium, this is a
sensible strategy and saves lots of messy fiddling. If you need to
delete either the debugging code or one or more or all reference clock
drivers to save space, see the Configuration
If your site supports multiple architectures and uses NFS to share
files, you can use a single source tree to compile executables for all
architectures. While running on a target architecture machine and with
the distribution base directory active, create a subdirectory using a
mkdir `config.guess`, which will create an
architecture-specific directory with name peculiar to the architecture
and operating system. Then change to this directory and configure with
../configure command. The remaining steps are the same
whether building in the base directory or in the subdirectory.
make command to compile all source modules,
construct the libraries and link the distribution. Expect few or no
cc and a moderate level of warnings using
gcc. Note: On some Unix platforms the use of
gcc can result in quite a few complaints about system
header files and type inconsistencies, especially about pointer
variables. This is usually the case when the system header files are not
up to ANSI standards or
gcc-isms. While the autoconfigure
process is quite thorough, the Unix programming cultures of the various
workstation makers still remain idiosyncratic.
As root, use the
make install command to install the
binaries in the destination directory. You must of course have write
permission on the install destination directory. This includes the
xntpd (the daemon),
dependent query program),
standard query program),
rdate replacement for boot time date setting and sloppy
time keeping) and
utility useful to find the primary (stratum-1) servers). In some
tickadj (a utility
useful to adjust kernel variables) is installed. If the precision time
kernel modifications are present, the
ntptime (a utility useful to debug
kernel time functions) is installed.
You are now ready to configure the daemon and start it. You will need
to create a NTP configuration file
ntp.conf and possibly a
cryptographic key file
ntp.keys. Directions for doing that
are in the Notes on Configuring NTP and Setting up
a NTP Subnet. A tutorial on debugging technique is in NTP Debugging Technique. If problems peculiar to
the particular hardware and software environment are suspected, browse
the Hints and Kinks page.
Bug reports of a general nature can be sent to David Mills (email@example.com). Bug reports of a specific nature on features implemented by the programmer corps mentioned in the Copyright page should be sent directly to the implementor listed in that page, with copy to firstname.lastname@example.org.
Please include the version of the source distribution (e.g., xntp3-5.87) in your bug report.
Please include the output of
your bug report.
It will look something like:
clean, but cleans out all directories in preparation for a new distribution release.
make distclean, but constructs compressed tar files for distribution. You must have GNU automake to perform this function.
Under Windows NT, you will need
Visual C++ 4.0 or above,
InstallShield SDK (comes with
Perl5 and some version of the archiving program
./scripts/wininstall/readme.nt file for
directions to compile the sources, build the libraries and link the
executables. Initiate the build by running either
blddbg.bat to compile all of the source and create an
InstallShield based graphical installation package.
To install the executables, make sure that you are logged in as a
system account, or one with administrator privileges such as the
"administrator" account. As part of the build an
InstallShield based graphical installer was created. Run
\xntp\scripts\wininstall\intel\disk1\setup.exe to begin the
installation. This installer will prompt for basic defaults, copy the
binaries, install the service, and start it up. The other option is
will do the basic installation from the command line.
