SetEnv PERL5LIB in htaccess for Apache 2.2 versus 1.3

monkfan has asked for the wisdom of the Perl Monks concerning the following question:

Dear all,
Running this piece of code is never a problem in Apache 1.3.

#!/usr/bin/perl
use CGI qw/:standard :html3/; 
use CGI::Carp qw( fatalsToBrowser );
$CGI::POST_MAX=1024 * 100;  # max 100K posts1 

 
 BEGIN {
     if ( $ENV{PERL5LIB} and $ENV{PERL5LIB} =~ /^(.*)$/ ) {

         # Blindly untaint.  Taintchecking is to protect
         # from Web data;
         # the environment is under our control.
         eval "use lib '$_';" foreach ( 
             reverse     
             split( /:/, $1 )          
         );              
     }
 }


use Acme::Spork;         
use Bio::Tools::GuessSeqFormat;
print "Content-type: text/html\n\n";
print "Hello World !! It works.\n";

It can recognize the path as set in .htaccess below:

SetEnv PERL5LIB  /home/monkfan/lib/perl5/site_perl/5.8.5/i386-linux-th
+read-multi:/home/monkfan/lib/perl5/site_perl/5.8.5
[download]

Then I upgraded from Apache 1.3 to 2.2 on the same Linux box. But now with Apache 2.2, it can't locate the location of those modules as set in the identical htaccess.

Does anybody has experience of setting PERL5LIB for htaccess in Apache 2.2? How can I resolve the problem above?

Regards,
Edward

This will depend on on other settings in your Apache configuration. Under some circumstances PERL5LIB is ignored. My personal preference for when additional library directories are required, is to define them under a different variable and incorporate that into a wrapping class. This stops me polluting the core perl variables, and it clearly shows the purpose. -=( Graq )=-	[reply]

Here's what I suggest: Somewhere in you apache config file, add something like this (the exact path can vary, of course): `PerlRequire /var/www/perl/startup.pl` [download] Then create startup.pl so that it looks like this: `use lib qw(/path/to/my/modules); use MY::MODULE; 1;` [download] The use lib line adds directories to the search path. If you actually put use MY::MODULE in the startup file, these modules will be preloaded when apache starts up.	[reply] [d/l] [select]

But now with Apache 2.2, it can't locate the location of those modules as set in the identical htaccess. It sounds (from the error message) like you need to go learn about Apache 2.2.	[reply]
