Thing is I have this Conn.pm in these many locations.
/usr/perl5/5.6.1/lib/Conn.pm
/usr/iplanet/perl5/lib/site/Mozilla/LDAP/Conn.pm
/usr/ds/v5.2/nsPerl5.005_03/lib/site/Mozilla/LDAP/Conn.pm
/usr/ds/v5.2/nsPerl5.006_01/lib/site/Mozilla/LDAP/Conn.pm
Where am I going wrong I tried adding the path in Use lib ...
If you have the line
use Mozilla::LDAP::Conn;
in your program, Perl will look in all the paths in @INC for a file with
the
relative path
Mozilla/LDAP/Conn.pm
so the first of these is no use at all as it doesn't have directories Mozilla
and LDAP in the path. The rest are fine, except that none of the locations are
in @INC. If you add any of
/usr/iplanet/perl5/lib/site
/usr/ds/v5.2/nsPerl5.005_03/lib/site
/usr/ds/v5.2/nsPerl5.006_01/lib/site
to @INC then Perl will find the module correctly. Which is the best place to
use depends on the way your system is set up and where other modules are
kept.
Thanks a lot for your reply.
I modified my perl file as follows , but still I get the same error.
use lib qw(/usr/perl5/5.6.1/lib/
130 /usr/iplanet/perl5/lib/site/Mozilla/LDAP/
131 /usr/ds/v5.2/nsPerl5.005_03/lib/site/Mozilla/LDAP/
132 /usr/ds/v5.2/nsPerl5.006_01/lib/site/Mozilla/LDAP/
133 /usr/ds/v5.2/nsPerl5.005_03/lib/site
134 );
135
136 #use Mozilla::LDAP::Conn;
137 print (@INC, "\n\n");
138

Hi Carl
(Please bottom-post your replies so that long threads like this one remain
comprehensible. Thanks.)
First of all, display the contents of @INC using
print "$_\n" foreach @INC;
then each element will appear on a separate line and the output will be more
readable.
Now you haven't understood what I wrote. Perl is looking for a file
Mozilla/LDAP/Conn.pm
in any of the paths in @INC. So with the 'use lib' line you have it will look
for
/usr/perl5/5.6.1/lib/Mozilla/LDAP/Conn.pm
/usr/iplanet/perl5/lib/site/Mozilla/LDAP/Mozilla/LDAP/Conn.pm
/usr/ds/v5.2/nsPerl5.005_03/lib/site/Mozilla/LDAP/Mozilla/LDAP/Conn.pm
/usr/ds/v5.2/nsPerl5.006_01/lib/site/Mozilla/LDAP/Mozilla/LDAP/Conn.pm
* /usr/ds/v5.2/nsPerl5.005_03/lib/site/Mozilla/LDAP/Conn.pm
yet according to your original post, Conn.pm exists at all of
/usr/perl5/5.6.1/lib/Conn.pm
/usr/iplanet/perl5/lib/site/Mozilla/LDAP/Conn.pm
* /usr/ds/v5.2/nsPerl5.005_03/lib/site/Mozilla/LDAP/Conn.pm
/usr/ds/v5.2/nsPerl5.006_01/lib/site/Mozilla/LDAP/Conn.pm
none of which exist except the one I've marked, which Perl should find if your
program and the locations of the module are as you say, so please check them.
The first of these is useless because it doesn't have Mozilla/LDAP in the path.
But the others are fine as long as you have ONE of
use lib qw(/usr/iplanet/perl5/lib/site);
use lib qw(/usr/ds/v5.2/nsPerl5.005_03/lib/site);
use lib qw(/usr/ds/v5.2/nsPerl5.006_01/lib/site);
As I said before, which one you choose depends on how your system is put
together and where other similar libraries are held.
I hope this helps.
