将编码与PAR Packer一起使用时要包括的内容 [英] What to include when using Encode with PAR Packer

问题描述

我一直在使用PAR :: Packer从Perl脚本中创建独立的可执行文件.我唯一遇到的困难是弄清楚我必须通过 -l <​​/code>选项强制它包括哪些额外的DLL.

I've been working with PAR::Packer to create standalone executable files out of Perl scripts. The only difficulty I have with it is figuring out what extra DLLs I have to force it to include via the -l option.

我现在正在使用需要使用utf16-le进行编码的Perl脚本. Encode :: find_encoding 函数在脚本中可以正常工作，但是在我将其与 pp 打包后无法正常工作.

I'm now working with a Perl script that requires Encoding with utf16-le. The Encode::find_encoding function works just fine in the script, but it doesn't work after I have packaged it with pp.

这里有一个小脚本(我们称它为encode.pl)来说明问题:

Here's a tiny script (let's call it encode.pl) to illustrate the problem:

use strict;
use warnings;
use Encode;
my $_UTF16 = Encode::find_encoding ('utf16-le');
print $_UTF16;

如果运行此命令，它将打印类似 Encode :: Unicode = HASH(xxxxxx)的内容.但是，用 pp 打包它，它将不再起作用:

If you run this, it will print something like Encode::Unicode=HASH(xxxxxx). Pack it up with pp, however, and it no longer works:

pp -o encode_test.exe encode_test.pl

现在，当我运行encode_test.exe时，我得到了:

Now when I run encode_test.exe, I get this:

Use of uninitialized value $_UTF16 in print at script/encode_test.pl line 5.

即使使用 pp 打包后，任何人都可以告诉我我需要做些什么(例如要包括哪些库或任何其他解决方案)以使这项工作正确进行?

Can anyone tell me what I need to do (e.g. what libraries to include or any other solution) to make this work right even after packaging with pp?

推荐答案

使用 -x 选项运行 pp 当然可以，但是我不接受使用它这种情况是因为它运行程序，并且因为这是一个GUI应用程序，所以该命令将不再是自动化的.

Running pp with the -x option works, of course, but using it was unacceptable in my case because this runs the program, and since this is a GUI application this command would no longer be automatable.

罪魁祸首是Encode.pm的第120行用于加载Encode :: Unicode的运行时要求.为了使该程序正常工作，我使用了以下内容:

The culprit was a run-time require used by Encode.pm, line 120, to load Encode::Unicode. To make this program work, I used the following:

pp -o encode_test.exe encode_test.pl -M C:/strawberry/perl/lib/Encode/Unicode.pm

请注意，使用反斜杠(Windows方式)会导致 pp 命令失败，因此必须将其替换为正斜杠.

Note that using backslashes (the Windows way) causes a failure in the pp command, so those had to be replaced with forward slashes.
