Re: custom module and lib
Hi All, I just tweak some of the regular modules under my lib and those who denied made it as pre-reqs I am still fighting for my exact solution On Thu, Feb 3, 2011 at 9:23 PM, Octavian Rasnita orasn...@gmail.com wrote: If you got a solution, it could be helpful for those who will find this thread on the web if you would explain what you did.

Do you have a special reason for wanting to rename Net::Rsh to Rsh? It is a dangerous thing to do, as there may well be code that relies on the name of the module being unchanged.

It is worth noting that, by default, the last entry in @INC is '.' - the current directory - so perl will ultimately look in the same directory as the calling program for all modules if they are not found elsewhere. So you can simple bundle Net::Rsh in the same place as your main program and any other modules.

Re: custom module and lib
Thanks much for your response!! Making it more clear.

At a guess you want to be able to access Net::Rsh as well as your own custom modules, in which case you probably don't understand how 'use lib' works, which is simply to add the path(s) you specify to the end of the list in @INC where perl will search for the modules you use. That means that, even after you have done 'use lib lib/test' you can still 'use Net::Rsh' and it will be found, as its location is still in @INC. For instance, something like use warnings; use strict; use lib 'lib/test'; use Net::Rsh; use SpecialModule; will find Net/Rsh.pm whereever it is on your machine, as well as lib/test/SpecialModule.pm If this isn't what you're looking for then please post again.

Regards, a b This is not possible if those dependencies use C code, because they must be compiled differently depending on the platform they are running on. This is the same no matter the programming language you use. If a module needs a .so file, under Windows it should be compiled as a .dll file. If they are pure Perl, then you can bundle them in that tarball as a part of that distribution. If you want to bundle more compiled Perl modules that use C code and use them under a specific platform and you don't need them to be portable, then you might be interested to create/install them as .deb or .rpm packages. I don't know (and maybe others know more about this) if it is possible to compile Perl modules that use C code and then install them on the target platform by just copying them on a custom location.

custom module and lib
Hello All, I have a query regarding using lib modules 1) I've some custom modules which uses various default routines like Net::rsh etc Now, i want to pack all default routines into my lib and use that lib in my custom modules i.e package MyModule; use lib lib/test;(here i am placing my Rsh.pm etc modules and some of my custom modules) use Rsh; Is this possible??? Please let me know how to go with this approach My motive is to create a main PM file which will call all small PM files(custom and defaults) Thanks in Advance!

Perl won't search your entire disk for the module, but rather it will look in well known places. :-) You'll want to put your SpecialModule in a well known place too if you want perl to find it. Or you can take a look at local::lib on the CPAN which can help you with precisely this.
