Not yet working :-( and quiet fastidious to setup the whole thing...
Puting Mapserver cgis in the apache cgi-bin directory and pointing at : 
http://localhost/cgi-bin/mapserv?
gives :
"No query information to decode. QUERY_STRING is set, but empty."

MapServer infos gives :
#mapserv -v
MapServer version 4.4.1 OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP SUPPORTS=FREETYPE 
INPUT=EEPL7 INPUT=JPEG INPUT=SHAPEFILE

But initializing Itasca demo gives :
"loadMapInternal(): General error message. Given map extent is invalid."
Quite uncommon mapserver error, isn't it ?

Apache error log file tells :
[Desktop Entry]
[...Date and time...] [warn] pid file /var/run/apache.pid overwritten -- 
Unclean shutdown of previous Apache run?]
[...Date and time...] [notice] Accept mutex: sysvsem (Default: sysvsem)]
[...Date and time...05:23] [notice] Apache/1.3.29 (Debian GNU/Linux) 
configured -- resuming normal operation]

I divided by ten the main and reference images size in demo.html and demo.map. 
Also removed the decimal of the main and reference images EXTENT. Does the 
reference image have to be of one of MapServer image INPUT types ?

How can I debug ? I have never used MapServer log files, could it be of any 
use ?
Do you think the RedHat trick I used to allow MapServer to build (previous 
post) is responsible for that error ? Or is it really some differences 
between gcc-2.95.2 and gcc-3.xx ?
This error is hard coded in mapfile.c and mapobject.c files. I am going to 
check these files, see also if I find a better trick that could allow a nice 
MapServer building, and try to slim Itasca demo step by step to see what is 
working and what is not.
One last thing : are bison and flex needed to compile nicely the basic 
MapServer cgi ? I have bison but it is not clear if flex is well installed or 
not.
Any ideas for debuging welcomed. Thks.
