Dear developers,

one bug fixed, but a new one occured...
Find attached a problem with MESA and
r3.showdspf.openGL

Comments are welcome. Siede note: I could
compile r3.showdspf.openGL without problems,
but attached problem was reported by Eric Mitchell,
too.

Kind regards

Markus

nit_graphics.c:629: undefined reference to `GLwCreateMDrawingArea'

I got the same message, and didn't find yet a solution. I think that the
problem is in Mesa-3.2/widgets-mesa : there is some file in the include
and src lib that call "GLwCreateMDrawingArea.c", etc...

But when you run the makefile, the libMesaGLw.a created only contains :

GLwDrawingArea.o
MesaDrawingArea.o
MesaWorkstation.o
GLwDrawingAreaMakeCurrent.o
GLwDrawingAreaSwapBuffers.o
GLwMakeCurrent.o

Maybe there is something to change in the makefile to include all functions,
add the library and run ldconfig before attempting to compile g3d
for Grass. I will try this tonight.

Markus, what version of Mesa do you have ? what version of Grass ?
(the latest, I presume :slight_smile: where is your libGLw.a file and where does
it come from ?

I compiled MESA 3.1 according to:
http://www.geog.uni-hannover.de/grass/grass5/README.mesa31

Mhh, somehow strange!

Hi,

this is as usual complicated:
The original sgi-widget set (in widgets-sgi of the mesa distr.), which
is copyrighted by SGI, is replaced with the beta widgets-mesa distr,
which seems not to be compiled by default. The README (of mesa 3.1)
says: "... Provide a GLwDrawingArea widget which is 100%ly compatible
with SGI's widget. Applications should port over with (almost) no
changes to the source... ... Status: The widgets work, but are in
differing stages of completion...". That does not sound very
encouraging.

I tried compiling r3.showdspf.openGL, but the Gmakefile (from GRASS 5.0
beta7) is for Solaris with Motif (includes /usr/dt/share!) and TODO-file
says: "Still need to convert to use OpenGL". Another document states:
..modifications made by Ken Sakai ...

I could'nt compile the mesa-widgets, because libMesaGLU is missing on my
system (i have libGLU). There seems to be an inconsistent way of naming
the libraries in mesa?

I will re-try this with mesa 3.2 in the next days and report again.

The function GLwCreateMDrawingArea is from libGLw and needs Motif as far
as i could figure out yesterday. The Motif parts from the widgets-mesa
directory are not very well tested until now. I think that Motif is
needed to compile libGLw, i have lesstif (0.86.5, very old version)
installed and could not compile r3.showdspf, produced the same error as
above.
