Re: Using STL containers in PDP++

["Randall C. O'Reilly" <oreilly@grey.colorado.edu>]

These errors indicate that maketa did not succeed, and the problems
are in the Environment classes so it looks like your <map> include
broke the maketa scan.  This is highly plausible, as maketa does not
handle the fancy template stuff in STL.  I suggest you add #ifndef
__MAKETA__ around the code involving this <map> and that should fix
it.  However, your <map> related code will not be accessible from the
script or gui (as these depend on maketa information).  Someday maketa
needs to be upgraded to handle these stl templates..
