If I'm using visualization, then a few environmental variables are on.
If I'm not using it, then I turn them off. In both cases, though, I may need
to link to the motif libraries. For example when I'm not using visualization
but I'm using user interface commands. It turns out that:

1) When I'm using visualization, I get no link errors against the motif
   libraries (I'm setting up openmotif v2_1_30 Linux+2.2)
2) When I'm not using visualization (but using UI commands), geant4 does not
   seem to locate openmotif v2_1_30 Linux+2.2. Instead, it picks up a
   system version which needs to be told explicitly about linking to the Xp
   libraries.

For now, I've fixed the problem by adding -lXp to config/sys/Linux-g++.gmk:

replaced line 39:
                  XMLIBS    := -lXm -lXpm
by:
	          XMLIBS    := -lXm -lXpm -lXp

Can you please specify which G4 setup you use for cases 1) and 2) ?
- For case 1), assuming you use a Motif-based vis-driver, you need to have
  built your libraries with G4VIS_BUILD_OPENGLXM_DRIVER (for OpenGL), and have
  G4VIS_USE_OPENGLXM set when you build/run your application.
- For case 2), assuming you use the Motif UI driver, you must have built
  your libraries with G4UI_BUILD_XM_SESSION, and have G4UI_USE_XM set
  when you build/run your application.
If the above conditions are satisfied, the setup for Motif is essentially
the same for vis/UI and you should not have any mis-match. The use/non-use
of the Motif-based drivers is controlled by setting/unsetting the G4VIS_USE_*
and G4UI_USE_* variables in your environment at the time you build/run your
application.

No futher user response.  Assume configuration corrected.
