Message-Id: <5ced5fcd-696d-426c-98b2-b648a7be69dd@w7g2000hsa.googlegroups.com>
Hi friends,
Perl 5.8.0 seems a bit strange. I encounterred a trouble in my dynamic
library which uses this symbol of Perl:
ld.so.1: perl: fatal: relocation error: file /opt/mylib/libAPIPerl.so:
symbol Perl_sv_2pv: referenced symbol not found
Killed
Solaris 9/10
Perl was built from source code tar ball.
zcyds4d6-85> perl -v
This is perl, v5.8.0 built for sun4-solaris-64int

But from perl5.6.1 to perl 5.8.8, I can find the reference in every
release except 5.8.0.
Perl5.8.4 sample:

Perl_sv_2pvutf8_nolen
The Perl 5.8.0 delta ( http://search.cpan.org/dist/perl/pod/perl58delta.pod#Perl_get_sv
) said that it that is no more the case. what does it mean?
Perl_get_sv
You may get errors like 'Undefined symbol "Perl_get_sv"' or "can't
resolve symbol 'Perl_get_sv'", or the symbol may be "Perl_sv_2pv".
This probably means that you are trying to use an older shared Perl
library (or extensions linked with such) with Perl 5.8.0 executable.
Perl used to have such a subroutine, but that is no more the case.
Check your shared library path, and any shared Perl libraries in those
directories.
Sometimes this problem may also indicate a partial Perl 5.8.0
installation, see "Mac OS X dyld undefined symbols"
I also found a link about this issue, but it did not say whether this
symbol was kept in Perl 5.8.0.
http://www.gossamer-threads.com/lists/engine?do=post_view_printable;post=6902;list=modperl
Why is Perl 5.8.0 so strange? How to resolve this problem?
Thanks in advance.

I don't think it's very useful to distinguish otherwise identical
postings in the subject. It might be useful to include the date when an
FAQ entry was *last changed* in the subject:
* FAQ entries which have been recently changed can be easily identified
* FAQ entries which are very old (and hence likely to be out-of-date)
can be easily identified
* a use could killfile each entry after reading it (perhaps for a
limited time) and still get the new version if the entry is updated.
(although given the number of different FAQ entries I doubt anyone
would do this).

*Great* suggestion. I've had a chance to look at this now and it
looks like a very effective way to proceed. XML::ApacheFOP actually
automates it more than I think I would need to. For those of you who
aren't familiar with this, there is an XML spec for document
formatting, called "XSL-FO". All of the [easy :o)] schemes to do the
type of document creation I had been thinkingof involve an
intermediate "markup" format for your document: HTML [for HTMLDOC]
LaTeX [for [La]Tex/dvi], even troff [for -ms and n/troff]. This is a
similar approach, but using an XML spec'ed format. It looks to be
fairly fancy [some of the online examples I've seen of what you can do
with XSL-FO are pretty slick]. Also, since it is XML you can
*GENERATE* it from other sources [cf XSLT].
The neat part is that compared to LaTeX the backend is comparatively
simple: Apache.org has written an XSL-FO =3Dto=3D nearlyanything
processing program writting in Java [the processor is called "FOP" and
the module referenced above basically automates spawning the JRE and
feeding FOP to it for you].
The XSL-FO spec is a bit complicated, but it doesn't seem all that bad
after you've tried wrestling with the LaTeX book [and don't even
*think* about trying to plow through the TeX book..:o)], so I'm going
to give it a try. THANKS!!

That's OK, I wanted an argument, not just the automatic gainsaying of

That will only happen if the directory if fairly small. Readdir uses a
fixed-size buffer (typically 8kB). On the first call in scalar context,
it reads a bunch of entries into the buffer and returns the filename
from the first entry. On subsequent calls, it returns filenames from
the other entries in the buffer, until the buffer is exhausted, then
it reads the second bunch of entries into the buffer, etc.
Hope this helps,

Hi all,
I am having to install the CGI module on a Windows XP machine
and it is very frustrating. I read that I should use the PPM to
install it, but the CGI module doesn't show up on the list of packages
that PPM can install. So I tried installing manually by downloading
the module and installing using nmake, dname, make.. none of which
work. I get a message saying "nmake" is not a recognized command. I
have installed perl modules on MACs a number of times and CPAN.pm
works like a dream. This is very frustrating and I would appreciate
any help in this regard. Thanks in advance for all your help.

CGI is a core module. What perl distribution are you using?
Did you check whether CGI is already present?

You need to have visual studio installed to use nmake. nmake comes as
a part of
Microsoft VC++. Are you using Active perl ?. I have done some
installation like DBI,DBD::Oracle etc on my Windows XP machine. It
went fine.

There's no way that I know of. Testing an applet would mean being able
to load a JVM, run the applet, and call its methods. Neither of the
web client modules I'm aware of (LWP and WWW::Mechanize) can do that.
There's a JVM module, if "offline" testing of your applet without its
surrounding HTML context is sufficient:
<http://search.cpan.org/~alknaff/Jvm-0.9.3/Jvm.pm>
I really wonder though, what's the point of using Perl to test Java?
There are plenty of native Java unit-testing tools, so why not simply
use one of those? I like Perl as much as the next guy (or gal), but
jumping through hoops to use it instead of a much easier solution in
another language is just plain silly.

JUnit is very popular, and integrated in a number of IDEs, such as
Eclipse and NetBeans:
<http://junit.sourceforge.net/>
JUnit is so popular that it's spawned an entire family of unit testing
tools, including one for Perl called Test::Unit:

That might have been more obvious had the OP not decided to format Perl
as if it is assembly language.
I realize beauty is in the eye of the beholder but I would urge the OP
to read
perldoc perlstyle
to ensure that his code is accessible to as many people as possible
(especially when requesting help in a public forum).

That would help.

Without even looking at your code my guess is that Yahoo! is not particularly
pleased about providing an ad-sponsored service to web-scrapers. Part of the
reason that free services change their page format is to block people from
doing this. Yahoo! changes their page format fairly frequently and I'm willing
to bet that their web programmers have access to CPAN. If you need 7000 quotes
then its pretty clearly not for your personal portfolio. Maybe time for your
company to invest in a quote service.

If you have good software, configured to do intensive filtering, data
for 7000 tradables can be easily managable for an individual trader.
On the other hand, if an individual trader needs a reliable and accurate
data feed for automated analysis, a free yahoo service is probably a
poor choice.
It sounds like the package in question is not as robust as it could be,
allowing the user to encounter a run-time undefined value error instead
of producing a good error message. However, yahoo changing the server's
behavior or data format seems a likely initial cause of the problem.

You don't need to emulate a right-click at all. All Explorer does is
execute a program or calls a DLL in the fashion specified by file extension.
Finding out how to execute the program can be easy or difficult, depending
on how it is called You can look at the file association used by windows
(In Explorer, click Tools->Folder Options->File Types. Find the select the
extension, then click the "Advanced" button. A list of "Actions" will be
displayed, select the action, and click "Edit". This will then show the
application that is executed. "%1" is the name of the selected file.
Sometimes its not this easy to figure out how windows does this, but since
no other input is required from the user when selecting the right-click menu
item, this will probably tell you which program is being executed.
Also check out the "C:\Documents and Settings\{loginname}\SendTo" directory.
This will list the "SendTo" items on the right-click menu. These will
either be a ".LNK" type or a zero byte file. If it is a link, you can see
the program associated with it by selecting it and clicking "Properties".
If it is a zero byte file, it will have a "dot" in it and the everything
after the dot is the file association. To find out how this works you will
need to some digging in the registry to figure out what program or DLL is
associated with that extension.
