I have seen others with similar problems (I had it on another machine
too ) mostly due to broken symlink,
but that does not seem to be the case here:

what to recompile with -fPIC?
libGL.a :(
if that is really the problem?
The main problem is that you have a static libGL rather than a shared
libGL. The GRASS build system tends to assume that all external
libraries
are shared libraries (unless building with --disable-shared, in which
case either will work).
You can probably work around it by removing $(OPENGLLIB) $(OPENGLULIB)
from the definition of EXTRA_LIBS in lib/ogsf/Makefile, and adding
them
either to the definition of OGSFLIB in include/Make/Grass.make[.in]
or to
the individual Makefiles (primarily, visualization/nviz/src/Makefile).
Actually, the NVIZ Makefile adds these explicitly, and r3.showdspf
is no
longer compiled, so simply removing them from lib/ogsf/Makefile will
probably suffice.
Glynn,
thank you for your help - removing $(OPENGLLIB) $(OPENGLULIB) from
the ogsf/Makefile solved the ogsf compilation problem.
The nviz compilation still gives a related error:

thanks you

Ideally, external shared libraries would be linked into the library
while
external static libraries would be linked into each module which
uses the
library. But I have no idea how to tell whether an external library is
shared or static; configure just checks whether adding "-l<library>"
works.
