Error while using packaged file using pp

m_k_venkataraman has asked for the wisdom of the Perl Monks concerning the following question:

I have just started learning Perl. I am developing a small quality check module for JATS XML.

While my Perl program is giving the desired output when executed as a standalone .pl program, it is giving me error as described below, if I execute the same program as package, packaged using PAR (pp -o file.exe file.pl).

Can you please let me know what may be the mistake I am doing in compilation? How can I avoid the error so that the packaged exe gives the same output (given below) as .pl execution.

-----------------Error

I'd recommend taking a closer look through the documentation for pp. You probably need to use the -c and/or -x options, which are used to "determine additional run-time dependencies". If you're still having issues after that, you may need to try use -M to specifically add in other needed modules that the pp utility is failing to detect and add to the bundle.	[reply]

Well, do you really need to use PAR? I am asking the question because you say that you are new to Perl and, maybe, you think that this is a standard way of using Perl. It isn't. The usual way is to use standalone Perl programs, using the `perl my_prog.pl` command under most systems, the shebang line under Unix and extension configuration under Windows. There are cases where you want to use PAR, but it is not the most common way of doing things.	[reply] [d/l]
