Global symbol "$psid" requires explicit package name at line 16.


I have a perl script which was written for me by a professional (I have some basic knowledge), is working fine at the moment but on moving it to a different server as I'm changing a server (new server is shared and supports perl modules), I get the following message

"Global symbol "$psid" requires explicit package name at line 16".

I get this for every single one for my values for the whole script which is about 2000 lines. Same error messages for main and admin.

I haven't changed anything on moving it to the new server apart from the first line which is the location of the perl.

I thought it would be too much to post the whole script here but anyone has any idea why is doing it taking into account that it works on a different server?

Mybe I did something wrong when installing or transfering the files?

Hello james2009, welcome to LQ,

you probably have forgotten to move not only the script to another computer but move the perl modules also to the new computer.

What I mean is, it seems that the programmer used modules which are not in the stock Perl-installation. So you will have to find out which modules that are (look at the begin of the program, modules are loaded with "use" or "require").

Another possibility: how old is the program? I remember when I learned Perl back in 1994, there was no "my" keyword. Is it possible, that you try to use a very old Perl-program with a recent Perl-installation?
