Although the online monitoring plugins will run in the online monitoring/L3 farm, it is convenient to develop them in an offline environment at collaborator's home institutions. The following describes how to do this:

1. Install Python and SCONS on your system.
2. Install the standard offline analysis software, including JANA and auxiliary packages needed (Xerces, etc).
3. Install the online SCONS-based build scripts:
   • On the CUE system they reside in: /group/halld-online/Software/builds/devel/buildScripts
   • Alternatively: svn co https://halldsvn.jlab.org/repos/trunk/online/packages/buildScripts/src/scripts
4. Set some build system environment variables. On the CUE system do as below, or similar if you installed the build scripts yourself:
   • $ setenv PYTHONPATH /group/halld-online/Software/builds/devel/buildScripts
   • $ setenv PERL5LIB /group/halld-online/Software/builds/devel/buildScripts
5. Check out the online monitoring package. The plugins reside in src/plugins:
   • $ svn co https://halldsvn.jlab.org/repos/trunk/online/packages/online_monitoring
6. Delete any plugin directory you are not interested in.
7. Build the plugins (without the "--std=c++11" compiler flag, default is to include this flag) and install the shared object files into online_monitoring/<arch>/plugins. From anywhere in the online_monitoring directory tree:
   • $ scons -D C++11=N install
8. Add the plugin directory to the JANA plugin path, execute something like:
   • $ setenv JANA_PLUGIN_PATH /group/halld-online/Users/ejw/builds/devel/packages/online_monitoring /Linux_RHEL6-x86_64-gcc4.4.7/plugins:"$JANA_PLUGIN_PATH"
9. Run hd_root, something like:
   • $ HALLD_HOME/bin/Linux_RHEL6-x86_64-gcc4.4.6/hd_root PPLUGINS="BCAL_online,CDC_online,FCAL_online,FDC_online" hdgeant_smeared.hddm
