DEM Import Problem: "null file"

I've been trying to use r.in.ll to import a gtopo30 dem file, and it keeps
failing with the message "warning: can't find a temporary null file.."

Anyone know the remedy for this? Many thanks, tom@bluesky.org

Hello!
I am a new grass user and try start
just compiled grass5.0b.

But my /usr/local/grass5.0beta/dev/
have not any files.

And can not load any maps.
my monitorcap from montcap.sample
have only one uncomment string:

x0:driver/XDRIVER:X-windows graphics display: \
     /usr/local/grass5.0beta/dev/fifo.1a
/usr/local/grass5.0beta/dev/fifo.1b \
     ::any terminal

what is fifo.1a?

Is it devise from my main UNIX dir?
/dev/-tty ?

Thanks for any help!

PS Linux for Debian with use TclTk - all start OK

fifo stands for first in first out
and means a special file which can be used as a pipe
between two programs. In this case the grass command and the X11
window displaying program.

It has nothing to do with your unix /dev devices.

I found the problem, that somewhere in the compilation and installation
the path to the "mknod" command is hardcoded.
Deleting the path from that command in generic/GISGEN.sh
might help to get the fifos created.

Watch the beginning of that normal compilation script to see the
messages about creting the fifos.
  
Hope that helps,
