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

ok, so I'm trying out a new package. If I unshift its directory onto @INC, then I still get an error during compilation that package is unfound, which makes sense to me. unshift(@INC,'/temp/packdir/') ; use MyNewPackage ; How can I get this to work? thanks

    Or: 
    use lib '/temp/packdir';

    Which pretty much does the same thing, and I personally like better.

    Cheers,

    You need to do the unshift in a BEGIN block: 
        BEGIN {
        unshift @INC, "/temp/packdir";
    }

    This is necessary because use is a compile-term directive. From the use docs, you find that use Module is exactly equivalent to 
         BEGIN { require Module; import Module LIST; }

    I have to agree with KM, either use the "use lib" pragma or edit your first line to read:
    #! perl -W -I /temp/packdir/
    Which of course only works on machines that use that line.

      I think you mean to have a lower-case 'w' there. -W does something in perl 5.6.x I beleive, but not in perl 5.005.
[reply]
        Correct, that is a 5.6 thing. I really wish people here would stick with -w in examples to ensure there is no confusion, since noone seems to comment 'This is for 5.6 and above only' when they do it.

        Cheers,
        KM
