in reply to CGI script fails to execute in browser

lib::MyDatasource(which I have created)

What did you do? How? What error messages did you get?

Error messages explain everything :)

Basically you need to add 

use lib '/absolute/path/to/where/you/installed/modules';
use MyDatasource;
...;

how does @INC work

You basically need work through the checklists (do what each item says, if it solves the problem GREAT, if it doesn't move on to NEXT item), brian's Guide to Solving Any Perl Problem, CGI Help Guide , Troubleshooting Perl CGI scripts ... More generic advice :) On debugging, verify everything, talk to teddybear ... checklists and more

Because https://httpd.apache.org/docs/2.2/howto/public_html.html#cgi / Apache Tutorial: Dynamic Content with CGI and more

Copy/paste from Re: To call a .pl file when a button is pressed on a GUI created using Perl CGI (webserver) for the links below

Its simple, you need a webserver

Why? Because webpages and CGI needs a webserver, thats how it works

Its weird that so many folks manage to create a GUI using Perl CGI without understanding this

And a copy-pasta for you:)

Also, there are checklists for that , Basic debugging checklist , brian's Guide to Solving Any Perl Problem, CGI Help Guide , Troubleshooting Perl CGI scripts

Yes, work through these checklists, when you find a problem on the list, use a solution from the list, when you find a problem not on the list (rare), post the error message and problem description here

So examine your server configuration and compare to https://httpd.apache.org/docs/2.2/howto/public_html.html#cgi / Apache Tutorial: Dynamic Content with CGI
