Message-Id: <7kaa3u$d6q$1@nnrp1.deja.com>
I am trying to install Perl 5.00404, but I keep getting the error
message:
/usr/bin/ld: cannot open -lgdbm: no file or directory
Can someone tell me how this problem can be corrected?
(I am installing Perl straight from the source. Although my
distribution (TurboLinux 1.0,kernel 2.036) installs Perl by default, I
removed it using the RPM package remover, in order to re-install
straight from the source. My eventual aim is to install mod_perl, and
it was my understanding that in order to do this, Perl itself should
also be installed from scratch, using the source).
Thank you.

You might consider getting Perl 5.00503 while you're at it.

`` Is the domain of this discussion computational?

`` POSIX declares that leap seconds shall not be reckoned.
POSIX can declare whatever they want. The truth is, leap seconds do happen.
Your system clock might never show '23:59:60', any data that has timestamps
on it *may* have 23:59:60 as a timestamp. Specially if it's coming from a
field like astronomy, or some place else, where they do think keeping time
is important.

Does POSIX compliance mean that your system clock has to be 22 seconds off?

You'd probably do yourself a favour by using the Perl module Bit::Vector,
which makes all this much easier!
It's internally written in C, so you get the speed of C combined with the
ease of use of Perl.
See my sig below for URLs where to download it from.
Hope this helps! :-)

How can I get the current working directory path and/or name, like "pwd"

Hi,
It depends ...
If you want to fork to launch child process and stay alive, you can use
Win32::Process module, if you want something else, I don't know :-)

Then in you are in big trouble because more often than not people will
simply refer to CPAN in that way.

So DJGPP isn't GNU?
<http://www.gnu.org/software/perl/perl.html> classifies Perl under GNU,
and <http://www.delorie.com/djgpp/> says:
DJGPP is a complete 32-bit C/C++ development system for Intel 80386
(and higher) PCs running DOS. It includes ports of many GNU
development utilities.
This is enough to make me believe that DJGPP Perl falls under GNU for
DOS.

Calling the Perl that comes with DJGPP "GNU Perl" is sort of like calling
the Perl that comes with Linux "Linux Perl" or the Perl that comes with
IRIX 6.5 "SGI Perl." It makes sense in the context of what you're talking
about, but it sounds like you're attributing authorship to "GNU," which
isn't correct.
I realize that technically "GNU" is just the operating system that the FSF
folks are putting together, and in that sense it makes as much sense to
include Perl in that as it does to include Perl in a Linux distribution.
But people will commonly read "GNU Perl" as "FSF Perl," and the FSF has
nothing to do with the writing or maintenance of Perl.

Yes - you can tie a filehandle. You could take a look at how I did it in
Win32::ASP - on CPAN, where I overload print to output to
$Response->Write (and do some buffer sizing stuff because
$Response->Write croaks on output > 12800b...).
Took me a bloody long time to figure out too... :)

Subject: Regular expresions as parameters
Message-Id: <3768C234.F2F911A9@realware.com.au>
Hi all,
I would like to be able to call a function passing it a hash of regular
expressions and a hash of field values. Both hashes will have a common
index (namely the field names) to which the field values correspond.
My function will then need to match key's in the two hashes and apply
the regular expression to the data for the corresponding key.
So I am wondering how do I pass a regular expression as a 'normal'
string inside a hash and then how do I make it behave like a regular
expression inside my function
# for example if I have a date string
$date_opened = "1999-01-01 10:15:00", # the following
$date_opened =~ s/(\w*) (.*)/$1/g; # removes the time component
but I would like to say this
%data_hash = ( date_opened => $date_opened
, #other keys and values );
%reg_hash = ( date_opened => "s/(\w*) (.*)/$1/g"
, #other keys and expressions );
%new_data_hash = myfunc( \%data_hash, \%reg_hash );
so new_data_hash would look like this
( date_opened => "1999-01-01"
, #other keys and modified values );
I guess in esscense I am asking is it possible to do this
$date_opened =~ $myreg_expression; # so that the regular expression gets
applied not assigned.
thanks for taking the time to read this, and thanks for any help you may
offer. I am reasonably new to perl so please do not assume to much
knowledge on my part when sending answers.
thanks a bunch

Hi,
is there a module for creating S/MIME encrypted mails with perl or a easy way
to create such mails using the MIME and encryption modules from CPAN?

Oh yeah.
import There is no builtin `import()' function. It is just an
ordinary method (subroutine) defined (or inherited) by
modules that wish to export names to another module.
Frankly, I don't see the difference with AUTOLOAD (see perlsub), or the
user defined subs to be used with tie() (see perltie), which are all
upper case only.
If, however, there is an `AUTOLOAD' subroutine defined
in the package or packages that were searched for the original
subroutine, then that `AUTOLOAD' subroutine is called...
perlsub:
A function in all capitals is a loosely-held convention
meaning it will be called indirectly by the run-time system
itself. Functions that do special, pre-defined things are
`BEGIN', `END', `AUTOLOAD', and `DESTROY'--plus all the
functions mentioned in the perltie manpage. The 5.005 release
adds `INIT' to this list.
In short: I think "IMPORT" would have made more sense than "import".

Well, after 6 months, here's the answer to the quiz: what do we do about
comp.lang.perl.moderated. Answer: nothing.

]It is possible to subscribe to comp.lang.perl.moderated as a mailing list.
]To do so, send mail to majordomo@eyrie.org with "subscribe clpm" in the
]body. Majordomo will then send you instructions on how to confirm your
]subscription. This is provided as a general service for those people who
]cannot receive the newsgroup for whatever reason or who just prefer to
]receive messages via e-mail.
The Perl-Users Digest is a retransmission of the USENET newsgroup
comp.lang.perl.misc. For subscription or unsubscription requests, send
the single line:
subscribe perl-users
or:
unsubscribe perl-users
to almanac@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.misc (and this Digest), send your
article to perl-users@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.announce, send your article to
clpa@perl.com.
To request back copies (available for a week or so), send your request
to almanac@ruby.oce.orst.edu with the command "send perl-users x.y",
where x is the volume number and y is the issue number.
The Meta-FAQ, an article containing information about the FAQ, is
available by requesting "send perl-users meta-faq". The real FAQ, as it
appeared last in the newsgroup, can be retrieved with the request "send
perl-users FAQ". Due to their sizes, neither the Meta-FAQ nor the FAQ
are included in the digest.
The "mini-FAQ", which is an updated version of the Meta-FAQ, is
available by requesting "send perl-users mini-faq". It appears twice
weekly in the group, but is not distributed in the digest.
For other requests pertaining to the digest, send mail to
perl-users-request@ruby.oce.orst.edu. Do not waste your time or mine
sending perl questions to the -request address, I don't have time to
answer them even if I did know the answer.
