in reply to Changing Perl compile-time configuration settings

Obviously it's sub-optimal to move the distribution every single time. It would be better if it just auto-detected the correct locations.

I've done a little experimentation with this...

Take a look at to see my experimental replacements for and CPAN/ (haven't done yet).

You might want to try copying those files into your install.

Of course, you'd have to also create a similarly-modified form of which you would then of course mail to me :)

    Hmm, your solution looks really nifty. I might switch to something like that when I've finished this attempt.

    My solution is to run a script which targets specific config settings for replacement. For CPAN's it does a little bit more than s/?:\\strawberry/$new_prefix/ (mostly pointing to some other include files on the flash drive). Perl's on the other hand just needs a search/replace done on it. looks like it needs a combination (and to be honest it hasn't been done properly! there's a lot of references to usr/lib and similar unixisms).

    I have a U3 drive because I like UltraEdit32 and the U3 version is pretty much everything you need for non-compiled languages. (I use it for Perl, Javascript, and XHTML).

    Here's the script so far, I'll get to work on it more tomorrow. It's a bit niave in some places (uh, like how I haven't used rename) and needs some of the debugging code stripped out.

    Looking at it's going to be a heavyweight combination of the two approaches I've used so far, and at this time of night the code's likely to read like the script from an episode of Deadwood.

      After a good night sleep isn't quite so scary. A s!.:/strawberry!$strawberryDir!g does most of the work, but there are these other options that probably shouldn't be left as they are because they still contain unix paths. This might account for the occasional X:\strawberry\perl\lib/foo/baa mangled paths seen in logs and error reports.

      Exerpts from
      glibpth='/usr/shlib /lib/pa1.1 /usr/lib/large /lib /usr/lib /usr/lib/ +386 /lib/386 /lib/large /usr/lib/small /lib/small /usr/ccs/lib /usr/u +cblib /usr/shlib ' ... locincpth='/usr/local/include /opt/local/include /usr/gnu/include /opt +/gnu/include /usr/GNU/include /opt/GNU/include' loclibpth='/usr/local/lib /opt/local/lib /usr/gnu/lib /opt/gnu/lib /us +r/GNU/lib /opt/GNU/lib' ... strings='/usr/include/string.h' ... sysman='/usr/man/man1' ... timeincl='/usr/include/sys/time.h ' ... xlibpth='/usr/lib/386 /lib/386'

      Update: Read Config manual page. Some of these are redundant. Others are easily redirected, and should really have been sorted during compile time, i.e. the Configure script didn't really set them correctly prior to compiling. It seems safe to redirect them to appropriate include and lib directories.

        I discovered exactly the same thing, nowhere nearly as scary as it first appeared.

        So I've implemented the auto-detecting version of as well, and added it to the repository.

        I've noticed the unix paths as well, but I'm unsure what the hell the implications of that are...

        Should I go through the makefile before I compile Perl and strip all those out? I dunno yet...
