Hi Martien;
Thank you very much. (And sorry about my typing, i forgot).
I understand, that there is a problem with versions of modules
i need, and possible overwriting of versions. But i think
i have the fortune for the moment, that target machines
are known for me, and the modules i use will not overwrite
anything.
As you told me, i found something about Bundles, in
(http://www.cpan.org/misc/cpan-faq.html#How_make_bundle),
and in man CPAN. I tried to build my own bundle, with some
examples. But i found that what happens, is that later
and using this bundle, tries to download from cpan the modules
of versions, which are not updated or installed in target machine.
How can i avoid this? I mean, couldn't this, be made off-line?
And another question is, are bundle files
cross-platform (i open my_bundle.pm, and found information
related to my machine)?
I have made some examples with Module::Install::Bundle, and
what this makes, is create an 'inc' directory, and
bundle there the source of the module (XML::Simple in this case).
So that i get everything in the same directory, ready
to be packed and distributed. I could read in docs that this module
checks for newer versions of these 'requires' in target machines
and only update if necessary ( i suppose that user is asked).
I also suppose that target machines do not need to download
from cpan (Can not this be made with the different bundle
option you told me?)
I have the same question for this module; Does this make
cross-platform installers (at least in linux)?
thank you very much for you interest.
Asier.
