Regenerating files using omniidl
http://omniorb.sourceforge.net/omni41/omniORB/omniORB005.html
In our HepRepCorba package, we save two *.idl files: HepRep.idl and HepEventServer.idl. We use these as input to the omniidl binary that is created when we compile omniOrb. These files must be regenerated each time we upgrade our version of OmniOrb.
omniidl -bcxx -Wba HepRep.idl
producing
HepRep.hh HepRepSK.cc, and HepRepDynSK.cc
...
In the HepRepCorba cmt requirements file there is a line
...
#Set some OmniOrb env variables
