[mapserver-users] Building mapserver with postgis

[Stephen Woodbridge]

Juan,

You might try running:

strace /usr/local/apache/cgi-bin/mapserv

Look at  "man strace" first to configure the command and log file. It
should journal all the system calls invoked by your command and you
should be able to hunt down what it was doing and what the error
responses where. I generates a TON of output, but can be useful for
tracking down obscur problems.
