[Mapserver-users] mapserv doesn't work

Fri Jun 20 23:10:02 EDT 2003

Vincent:
  I recheck the mapserv in apache cgi-bin is the
mapserv i just compiled. If i change its name, the
brower will say object not found.

  then i try 
http://localhost/cgi-bin/mapserv?map=/var/www/html/itasca/itasca.map&mode=map
  the problem remain, message is 

     Error message:
Premature end of script headers: mapserv 

  It seems something wrong in my platform, but i just
can't find out :<
  Just a wonder. Why not mapserver build a easy to
used rpm package for us newbies to play?
