Thank you.  I made the changes you suggested:

Added these lines to include/mg.h:
  extern int mgdevice_OPENGL( void );
  #define MGD_OPENGL	8
Set makefiles/mk.alpha to have:
  CPU = alpha
  MACHTYPE = x11
  GVTYPE = x11
  MGTYPE = -MGOPENGL

"make all" then died with the following.  Apparently it could not find the
mgopenglP.h file in the expected include area.

----------------------------------------
rm -f mgopengldraw.o mgopengldraw.c
ln ../mgopengldraw.c .
cc -I.. -g   -DMACHTYPE='"x11"' -I../../../../../include  -c mgopengldraw.c

ERROR: no rule for ../../../../../include/mgopenglP.h in Makefile in directory
/tmp_mnt/net/rtp8/zeleznik/geomview/Geomview.alphaGL/src/lib/mg/opengl/O.x11

exit: No such file or directory
----------------------------------------

I found mgopenglP.h in src/lib/mg/opengl/mgopenglP.h, and so put in a link
from the include area to where it lived:

 include/mgopenglP.h -> ../src/lib/mg/opengl/mgopenglP.h

This got further, but it now dies with an undefined type "snap_entry".  I
do not see snap_entry defined anwhere in the source tree.

----------------------------------------
rm -f gvmain.o gvmain.c
ln ../gvmain.c .
cc -I.. -g  -DMGX11 -Ddark_ui -DMACHTYPE='"x11"' -I../../../../../include  -c gvmain.c
/usr/lib/cmplrs/cc/cfe: Error: gvmain.c, line 24: Syntax Error
 snap_entry snapshot_table[] =
 -----------^
----------------------------------------

Thanks again for your help!
