After reading about local::lib and thinking that it's too good to be
true, I just had to try it out as a possible deployment method for one
of our apps. I have the app and all dependencies running on my
development box. The prerequisites are specified in my app's
Makefile.PL. Now, after having bootstrapped local::lib, I ran the
following commands - as suggested by t0m in a recent thread - but
nothing happens because all required modules are already installed in
my system-wide CPAN directory in their correct versions:
Yeah, unfortunately, this doesn't work so good unless your
dependencies have been installed in a local::lib themselves, and you
can remove this from PERL5LIB
After rambling about 'just do it like this', I then wandered off and
tried to make the new --self-contained feature of this work. Wasn't
quite as easy to make it work generically than I'd implied I don't
think.
$ eval $(perl -I$HOME/perl5/lib/perl5 -Mlocal::lib=--self-
contained,local_lib)
$ make installdeps
Am I missing something here or do I really have to checkout my app on
a fresh installation with no prerequisites installed and try the above
there?
Yeah, pretty much at the moment. If you install all your
prerequisites in a local::lib, then if you blank PERL5LIB, then it
_just works_.
However have a look at:
http://bobtfish.livejournal.com/264777.html
http://github.com/bobtfish/catalyst-app-example-locallibapp/tree/master
This is what I threw together after making that posting, and whilst
it's not quite all there yet - it will at least install a self
contained Catalyst & etc.
Also, am I right that this method won't work for XS-based modules if
I'm building my local_lib, say on a Ubuntu system, while the
production system is Debian-based?
Correct. You'll have to build your local::lib on a system with
similar architecture to your production boxen.
Cheers
