[GRASS5] Debian and d.m/d.zoom bug - /etc/ld.so.conf

[Markus Neteler]

Hi,

from Paolo C. I got temporary access to a Debian box
to check the problem with d.zoom in the display manager.

The idea is to avoid the /etc/ld/so.conf hack which is
necessary to make d.m/d.zoom functional:

See:
 http://grass.itc.it/pipermail/grassuser/2004-November/027112.html

First test:
echo $LD_LIBRARY_PATH
/usr/local/grass5.7.cvs-i686-pc-linux-gnu-25_11_2004/lib
...looks ok. Ans this directory contains the libs.

I found out so far:
- d.zoom on CMD line works;
- d.m/d.zoom (icon) fails: for microseconds the requested terminal
  is opened, then it closes. no error message.

Looking into the code, I found that in effect next line is executed
in the display manager:
 xterm -e d.zoom
Running this command on command line provides the same undesired 
behaviour (immediate closing of xterm after launching).

Interestingly, when running
 strace xterm -e d.zoom
it works!

ldd `which strace`
        libc.so.6 => /lib/tls/libc.so.6 (0x41019000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x41000000)
doesn't report anything special,
nor:

        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x41000000)

Any suggestions how to proceed? Maybe the xterm doesn't work as
desired under Debian (why does it then with strace)?
