Using Eclipse 3.0 final version, and Eclipse plugin 0.3.0.
Windows XP platform.

If I define perl to be located at the UNC path
\\server\share\path\to\perl\bin\perl, then when I do
Source -> Format I get a windows pop up box that says

The application or DLL
UNC\server\share\path\to\perl\site\lib\auto\HTML\Parser\ Parser.dll is not a valid window image. Check your
installation diskettes.

After I click OK, then it does seem to format OK.

If I change perl to be defined to a perl that is local to
my system, then no errors come from Source -> Format.

Any ideas?
Could it be the UNC version of Perl is corrupt?
I am not exporting to HTML, so therew's no reason to be
looking at an HTML parser anyways.

Not as a solution, but as a workaround:

Wouldn't it be possible to map the UNC to a drive? I guess,
the problem will vanish.

Mapping the UNC to a drive letter and then using the drive
letter path to perl did not help this. The only thing that
changed was the new path to perl was shown in the popup
error box.

Could you check if you have enough write-privileges on the
UNC-path? If not => that's the reason of the Error!

I do not have write permissions at the UNC Path in the perl
directories (couldn't make a new file for example). It's
strange you would need write permissions there.

I guess it's not restricted to the UNC, it could happen
anywhere!!!

So can it be worked on so you don't need write permission to
the perl install directory to do a Source->Format with
throwing an error?

Could you check if you could access from your UNC-path to
the local path of Eclipse?

I personally do not any longer believe it is related with
write-access issues. I guess more it's a Java-restriction. But
wanna get sure.

Also, what's not mentioned up till now: Perl itself works, ie.
you could excute scripts? you could get also the perldoc?
These two questions would help for a workaround.

Additionally: If you would call manually on the UNC-path perl
perltidy ... this works or not?

A lot of question, but in order to provide a fix all should be

Perl itself works fine and there's no problem getting the perl
doc or running scripts.

If I call perl tidy on the command line as follows:

UNC-PATH-TO-PERL -I<PATH-TO-PLUIGIN-SO-PERL/TIDY.pm-
IS FOUND> <Path to perltidy> <file to indent>

Then I get the same error as I do when within eclipse.

I didn't know what you meant by "Could you check if you
could access from your UNC-path to the local path of
Eclipse", so I didn't answer that.

Hope this helps!
Thanks!

My guess:

Perl is executed on a (UNC)host. And from this host, where
Perl is executed, it could not access to your host, namely
where the Tidy.pm is located. Therefore the question if you
perform Perl and then make something like Ping to your host
(or something equivalent) I highly guess, you cannot reach
your localPC. Only one-way direction.

I'm not THAT Perl-expert, so I don't know how to make
something like Ping on THAT UNC-host. That's your task -
sorry, but have no other options available.

Other additional question: Is Tidy.pm somewhere found that
UNC-Host?

The perl process runs on my local box, not on the host
machine of the UNC.

Tidy.pm is only found on my local PC in the installation of the
plug in, there is no tidy.pm in the perl distribution at the UNC
path.

Things *are* getting formatted, so Tidy.pm is running...

HM', perhaps I missunderstand something:

1) How is it possible that perl runs on your machine, when it is
installed on the UNC-path? Or does this mean you have also
local installation? But still, I do not get it, how this local Perl
could be excecuted, when you specify a remote one.

2) How do you come to the conclusion of your last paragraph?
i.e. from where could you detect Tidy.pm was running?

• Leo Sager - 2004-10-11

Perl is installed on some file server (unc path). But when you
execute it, it doesn't run on that file server, it runs on the
computer where you are running it from (aka, the perl.exe is
executing on my local machine).

By examining the @INC path, I looked for Tidy.pm and only
the one in the plug in is found.

Hm', I still have my doubts, buttttt.....

How do you configure the perl Statement in the preferences?
If I do it like "\\hostname\perldir\perl" I get an Error as
well if I type it in the DOS-box

'\\hostname\perldir\perl' is not recognized as an internal
or external command, operable program or batch file.

So, what's the magic trick to perform this statement as well
in the DOS-box?

BTW: Could you test the following script:

use Sys::Hostname;
print hostname();

Is it the UNC-hostname or your localhost-name???

In the preferences, perl is defined as:

\\febbos001na\releng\perl\win32\bin\perl.exe

The hostname prints out as my hostname.

Can you reproduce this bug in 0.4.x? If not, I vote for
closing it as 'Out of Date'.
