Once the user has modified these configuration files as desired, configuration proceeds when the user runs the $JSOCROOT/configure script. This script first determines if the build to be performed is a JSOC-SDP DRMS build, or a NetDRMS build. If $JSOCROOT/configsdp.txt is present, then it will assume the former, otherwise it will assume the latter. If performing a NetDRMS build, then the script requires that config.local be present. For a JSOC-SDP DRMS build, the presence of this file is NOT required. If it is present, then the contents of that file will customize the JSOC-SDP DRMS build, but if it is absent, then a default build will be performed. |
Build Configuration
The source-code configure script, $JSOCROOT/configure, sets environment variables, make variables, and creates on-the-fly make rules that allow users to localize and/or customize the way the JSOC-SDP code is built. Depending on how the make system is configured with these variables and rules, the user can build NetDRMS or the DRMS used at the JSOC-SDP. And for both builds, the user can customize various details.
A user controls configuration by editing one or more configuration files:
configureBR This is the master script that a user runs before they run make. It needs to be run once after source-code and make-configuration changes, but it does not need to be run when building on a new platform.
