Thanks for the reply.
I did some more digging around and came up with the following:
http://guest:guest@rt.perl.org/rt3/index.html?q=37376
!!!!!!!! It's a PERL BUG !! which should be fixed in perl 5.9.3.
But 5.9.3 is giving me a other problems with several modules....

Hi,
I am reorganizing some of my Perl code to place modules where they can
be found via environment variable PERL5LIB. Some namespace issues are
not working as I would have expected, and I have not been able to find a
nice piece of documentation to explain this.
For example, consider this scenario:
I have directory MyLib (present in $PERL5LIB), which contains two
subdirectories Foo and Bar. Foo contains a module FooTools.pm, and Bar
contains BarTools.pm, i.e. the files MyLib/Foo/FooTools.pm and
MyLib/Bar/BarTools.pm both exist.
In FooTools.pm, I have:
use Bar::BarTools;
Later in FooTools.pm, I want to use a function func() that lives in
BarTools.pm. I expected this to work:
Bar::BarTools::func();
It did not, telling me that it could not find the function, though it is
certainly present in MyLib/Bar/BarTools.pm. This, however, *did* work:
BarTools::func();
Why is it that 'Bar' must be present in the 'use' statement (as I would
in fact expect), but cannot be present when I call the function? I would
have expected a fully qualified name always to work.
What would happen if there were a module BarTools in Foo, and I had done
this in FooTools.pm:
use Bar::BarTools;
use Foo::BarTools;
...
BarTools::func();
?
Would Bar::BarTools::func() work only if there were such a conflict?
Any help or pointers much appreciated.
Regards,
David

Message-Id: <XO-dnQCI-KUD7qvZnZ2dnUVZ_tKdnZ2d@speakeasy.net>
Hi,
I'm a perl hack and want to distribute a windows executable of one of my
scripts. When I invoke the perl compiler by using perlcc, I get the
following error.
perlcc.bat: Can't unlink error file pccrYVGS
If I try multiple times, the error is the same but the filename changes.
I googled and didn't see anything that would help me.
One thing I did find out was that a recent installation of some
development tools blew away portions of my 'path' environment variable,
including the path to the perl bin directory (which also has
perlcc.bat). I have restored this to the path and it works (I can invoke
perlcc from any directory). However, I'm wondering if there is some
other path element that needs to be in place to prevent this error.
Here's the particulars for my system.
Platform: Windows 2000, SP4
Version: ActiveState v5.6.1
TIA

Have you read the documentation for the tool you want to use?
DESCRIPTION
perlcc creates standalone executables from Perl programs, using the
code generators provided by the B module. At present, you may either
create executable Perl bytecode, using the "-B" option, or generate and
compile C files using the standard and 'optimised' C backends.
The code generated in this way is not guaranteed to work. The whole
codegen suite ("perlcc" included) should be considered very experimen-
tal. Use for production purposes is strongly discouraged.

You need to take a look at par for this

Many thanks for the explantation! You mean, $a becomes an alias
for $3, @a for @3, %a for %3, and so on.
But what do you mean with "symref"? I thought "*x" means "the
glob of the variable x".

I don't know, but try:
$ perl -Dt -e 'print @x'
and you'll see:
....
(-e:1) gv (main::x)
(-e:1) rv2av
(-e:1) print
....
Maybe "gv" returns a reference to the given glob, and "rv2av"
dereferences the array entry in order to pass the list to print?
Again, thanks for your answer, and kinfd greetings, Ferry

Quite so.

That's true if x is a valid Perl identifier (a variable name without
the sigil $, %, ..., * in our case), which "3" isn't.
The general rule is: The identifier can be substituted with a block
that returns a reference (of the right kind, if applicable). The reference
can be a real one or a symbolic one. Also, the block braces can be
dropped when there is no ambiguity. That is what happens here.
