PSRCHIVE Administration Guide

System Installation

At sites where some level of stability is important, it is useful to maintain previous working versions of compiled binaries and revert to these if the development version is corrupted or lost.

The PSRCHIVE distribution comes with two useful scripts to aid in the management of a system installation directory. These are found in 

Management/psrchive_install
Management/psrchive_version
Both of these scripts make use of the PSRCHIVE_SYSTEM environment variable, which must be set to the root directory in which you wish to install the version control system. For example: 
setenv PSRCHIVE_SYSTEM /nfs/pulsar/linux/psrchive
After setting this environment variable, a PSRCHIVE Release may be installed with the command 
psrchive_install VER
where VER is the SourceForge Release Name (version number). The psrchive_install script will
  1. download psrchive-VER.tar.gz from the nearest SourceForge mirror;

  2. unpack and run configure, make, make check, and make install;

  3. install a read-only copy of the software in $PSRCHIVE_SYSTEM/$VER;

  4. update the stable symbolic link to point to the new installation; and

  5. if the PSRCHIVE_SYSGRP environment variable is set, then the group ownership of the newly installed files will be set to it.
The psrchive_install script uses curl to download the tarball. If this step fails, you may have to set the http_proxy environment variable.
