Re: building module/package
Thanks for your help. I had tried the use lib "path/to/module"; and use module; but it is still complaining about the use module part. However, I took the easy route but may annoy structured folks, like perl is very structured. I put it in /usr/lib/perl5/5.8.0 It works! Yippee! Perl programming is cryptic anyway, isn't it? Just let the next programmer figure it out. just like, [EMAIL PROTECTED]&(2.3), that suppose to mean something ;) Just to keep on chugging, I'll take it out of there as soon as I can figure it out. I know it's probably a one liner in the httpd.conf file but I have mod_perl folks telling me to read the whole website! oh well, thanks. -rkl > > > --On Monday, September 29, 2003 23:53 -0700 "[EMAIL PROTECTED]" > <[EMAIL PROTECTED]> wrote: > >> -I've sent this to the mod_perl list but there seems to be no >> response. >> >> I got the module working in the current directory executing on the >> command line.

RE: building module/package
Besides the advice given below, there are a few other things you can do... To add the location of the Perl script to the lib path you can use this. The FindBin module finds your script, then sets $Bin to that location. use FindBin qw($Bin); use lib $Bin; Another way to do it is to set the environment variable PERL5LIB to the location of your home-grown modules. You can set this in the Apache config (or .htaccess file) with the setenv command (see Apache docs for more info, but I think it is "setenv PERL5LIB /path/to/lib"). You could also install it into the "site_perl" directory in your @INC path, but you should never put it in the "vendor_perl" directories. Of the above options I would recommend using the PERL5LIB env variable. ...And I would also recommend that the libraries not be put in any directory accessable to the web server (unless you have no choice).

Re: building module/package
Daniel:
-I've sent this to the mod_perl list but there seems to be no response.
I got the module working in the current directory executing on the command
line. But I have a problem calling a module in my mod_perl dir using
apache on redhat 9. I have a mystuff.pm in the same directory as the
calling perl program. I got it working running on the command line but in
apache mod_perl, it can't find the module.
Questions:
- Where should the mystuff.pm be located in?
- The only place i know about mod_perl configuration file is:
/etc/httpd/conf.d/perl.conf. This contains the Alias and Directory
directive.
Error message:
Can't locate mystuff.pm in @INC (@INC contains:
/usr/lib/perl5/5.8.0/i386-linux-thread-multi /usr/lib/perl5/5.8.0

Any help would be great.
By the way, I just getting started with perl.

You're almost good. Add '1;' to the end of mystuff.pm, just to
return a true value when it compiles, and 'package mystuff;' to the
beginning of the same so Perl knows it is a package. Also 'use
warnings' and 'use strict' would be good in both...
As for where you put it: wherever you want. Just make sure that it
gets included in the @INC path. The easiest is in the same folder as
test.pl (assuming you always run test.pl from there), since the
current folder is in the path.
