[Mapserver-users] mapserv doesn't work

Mon Jun 23 19:12:16 PDT 2003

Pericles:
  Thank you! I really find the root of my failure. I
check the log of apache, there is something wrong with
libgd. Here is the content of error_log. I don't know
why mapserver try to find libgd.so.2 when i run in cgi
mode. But it work fine when it is used in command
line. What's up?
