[winGRASS] Installation problem native win version

[Jonathan Aguero]

I worked more in the locking problem today and found a partial solution.

I commented the following lines in the /grass/etc/init.sh file:

# Check for concurrent use

#lockfile="$LOCATION/.gislock"

#"$ETC/lock" "$lockfile" $$

#case $? in

#    0) ;;

#    1)

#    echo $USER is currently running GRASS in selected mapset. Concurrent
use not allowed.

#    rm -rf "$tmp"  # remove session files from tmpdir

#    exit 1 ;;

#    *)

#    echo Unable to properly access "$lockfile"

#    echo Please notify system personel.

#    exit 1 ;;

#esac

The symbol # before the line made it a comment and the locking is not
performed by GRASS. As mention in other mails, concurrence might not be a
problem in windows.

It seems like many other people experienced this problem but GRASS keeps
going while in some other systems crashes, it might be a difference in how
updated XP is.

Note that this is a very pedestrian solution, GRASS programmers could come
up with a better one but in the mean time this may get you going with
WINGRASS.

Dear listers,

I downloaded and installed the new native version of winGRASS yesterday. The
installation apparently was successful but when I tried to start GRASS after
I selected the location and mapset it flashed the following message:

Locking is not supported in Windows!

and close the window.

I did not install PG 8.1 since I have the 8.0 version and I wanted to save
the trouble so I modify the grass.bat the see at the 8.0 folder. Anyway the
problem seems more OS related than PG related. My OS is XP professional SP2.

Thanks in advance for your help.
