[GRASSLIST:6127] nviz startup script error

GRASS GRASS user

Hi;
I've recently installed grass5.0.2. And I've tried to execute nviz with the
following result:
-----------------------

----------------------------------------------------
I couldn't install readline (could this have any relationship?)
What could I do?

Thanks and regards

Your OpenGL library isn't compatible with your X server.

Basically, you have a "real" OpenGL library, which expects the X
server to do the actual OpenGL rendering (unlike Mesa, which does the
rendering itself).

If you're using XFree86 4.x, you need to have:

    Load "glx"

in the "Module" section of the XF86Config file.

You can use the "glxinfo" utility to check whether your X server is
set up correctly.

Alternatively, you could use Mesa, which does the rendering itself,
and sends the rendered image to the X server (consequently, it doesn't
need GLX support in the X server).

No. The readline library is optional, and is only used by r.mapcalc.
