I'm lost why your program doesn't show anything in the error log. So
these are just some wild guesses to collect some information which
might give some hints:
- I'm pretty sure that you didn't tie $root to some extremely strange
process which silently exit()s on FETCH? ;->
- Print %INC before creating the template. Maybe (mod_perl comes
into my mind) for *some* paths in the server there are different
settings, e.g. for PERL5LIB than for *others*.
- Print %ENV, basically for the same reasons.
- Wrap your program into a simple shell script like this:
#!/bin/bash
PERLDB_OPTS="NonStop LineInfo=your.log.file frame=2" perl -d xx.cgi
(make sure that the web server is allowed to create and write to
your.log.file). This prints a complete history of subroutine calls
and exits and might give a hint where exactly the program exits (or
hangs?). Be aware that the output may be some MB if your program
does many things (e.g. CGI related) before vanishing.
And anyway: Even if your program is designed to work as a CGI, I think
it is always worthwile to create an environment where you can test it
from the command line. CGI.pm has this ability built-in, all you may
need is to mock up some additional environment variables.
