in reply to How is the default @INC constructed?

I imagine it's built from a constant in Config.pm. Config.pm is created when perl is built based on compiler flags and whatnot. (And in turn, Config.pm is used to extract options needed to compile modules.)

    Not quite. How would it find Config.pm without knowing the @INC?

    The answer, as others have said, is that @INC is built in to the Perl binary, so you can't change it without recompiling the binary.

      *sigh* Too true. I must have bonked myself on the head too many times.

      Are some generated instead of being hardcoded? I orignally installed my ActiveState perl in R:\U, but recently moved it to R:\Utils (without reinstalling), and I get:

      >perl -le "$,=', '; print @INC" r:/Utils/perl/lib, r:/Utils/perl/site/lib, .

      I did have to edit Config.pm for PPM to work in the new directory.

        They appear to be, ap rime example is are win32 builds (can;t assume you mean win32 by activestate because they offer solaris and linux too). But if you try IndigoPerl and run it with -V it's likely to spew things which have no relevance to your machine, and yet it manages to run just fine (though error messages about "use" can be b0rked)
