Require files

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

I have a few different questions that I hope someone can clear up.

An error I am getting from one of my scripts is "/home/everyday/public_html/upload.cgi did not return a true value at /home/everyday/public_html/index.cgi line 66.". Which of the two files should I be looking at to find where the bug is?

Question 2: both the files as seen in the error above require() files at the top of the scripts. When the script says upload.cgi did not return a true value, is it just upload.cgi that errored out or could it be the require("header.cgi"); that's at the top of the script? And when doing line counts in upload.cgi for line 66, is it 66 lines in that file or do I have to count 1 - (first req. file line), count all those lines, then go back to my upload.cgi? I have no idea what line could be wrong because it's requiring() a file.

Last but not least, the following snippet dies

if (!defined($index_page))
{
    require("header.cgi");
    $main_content = $ENV{"DOCUMENT_ROOT"} . "/upload.cgi";
        #print "test";
        print $index_page;
    require($index_page);    
    exit;
}

The error is "Compilation failed in require at upload.cgi line 15.". I included a test print statement fir $index_page (which is the one that's failing) and it's printing "home/everyday/public_html/index.cgi" and that file does exist and it works!. So what could be the problem?

Thanks for your help everyone.

I suspect that `header.cgi` is 66 lines long. Perl `require` demands that the file it loads return a true value to signify success. Try appending this to the end of `header.cgi`: `1;` and see if that doesn't fix the problem. After Compline, Zaxo	[reply] [d/l]

Okay, I added 1; to the last line of all the files I'm requiring and it didn't change. The compilation error is still present. Any other suggestions? Thanks!	[reply]

It doesn't seem likely, but do you have a `return;` or `return 0;` statement somewhere outside a `sub` definition in the `require`d file? It would help save wear and tear on my guesser if you showed us the file. Particularly, line 66 and prior. After Compline, Zaxo	[reply]

any included modules ( via `require` or `use` need to return a true value. normally, this is achieved by ending a module with: `## penultimate line 1;` [download] so i would check header.cgi to see if it returns that value. the same applies to all other `require`d code.	[reply] [d/l] [select]
