Hi everyone,
I posed a question about compiling a while ago and got this
response (below). It occurred to me that some of the text looked like
things one might type into the window (a DOS window I believe it's called)
that I run PERL programs from. When I typed in "perldoc perlcompile" I
got a ton of information. The most interesting part was this:
To turn a Perl program into executable byte code, you can use 'perlcc'
with the '-b' switch:
perlcc –b myperlprogram.pl
Very exciting - that's exactly what I want! So I whipped up a
silly little 2 line program to try as a test of this called
bytecodetry.pl. I typed in "perlcc -b bytecodetry.pl" and got the
following results:
1) I saw this in the DOS window:
---------------------------------------------------------
Compiling bytecodetry.pl
---------------------------------------------------------
Making Bytecode (bytecodetry.plc) for bytecodetry.pl!
C:\Perl\bin\Perl.exe -IC:/Perl/lib -IC:/Perl/site/lib -I. -MB::Stash
-c bytecodetry.pl
2) Despite a blinking cursor on the next line, the computer
became almost entirely non-functional. A window called MS-DOS prompt
appeared, which said:
This program has performed an illegal operation and will be
terminated. Quit all programs, and then restart your computer.
If the program consistently encounters problems, click the Start
button, then select Help, Troubleshooting, and 'If you have trouble running
MS-DOS programs'.
I could respond with OK or get Details. The details were:
The program encountered a general protection exception
Fault location: 0028:0003
Interrupts in service: None
3) The computer made a file called bytecodetry.plc. That file
had one line:
#!C:\Perl\bin\Perl.exe_use ByteLoader 0.03;_
(Only the underscores weren't underscores, they were solid blocks,
which seem to represent returns, because that's what they became when I cut
and pasted it.) Despite a couple zeroes near the end there, that doesn't
look very binary to me. What's that all about?
Any help would be appreciated. Why is this illegal? Did I get
byte code? If so where is it?

perl *is* a compiler. :-)
perldoc perlcompile

Do you Yahoo!?
Get on board. You're invited to try the new Yahoo! Mail.
I assume you want this to execute this perl code and run independent of Perl
being installed, not just obfuscate your code so people cant read the
source? Did you try google?
PAR may solve your probem, though I don't explicitly know what you need or
why:

(wiki with links to CPAN)
It looks like sourceforge has an open-source project for it named perlbin.
http://perlbin.sourceforge.net/perlbin-0.01.html
It also looks like people have had lots of trouble trying to get perlcc to
work.
Depending on how many times you will actually need to do this it may not be
worth figuring out all your flags for perlcc. You might want to try what
this person did:
http://www.vdomck.org/blog/2005/09/23/perl-scripts-for-perl-less-people/
I know Ive seen commercial utilities to do this and that always puzzled me.
Now I see why , the perlcc -B failed to compile my perl scripts as well.
Researching it, indicates its experimental and was probably started as a
path to turn the perl source into C. The few people I saw that had finally
gotten it to work used a lot of flags.There are dependencies.
ActiveState's Dev Kit has the ability to do this and a 21 day trial:

perl2exe is the first one I think I ever saw ( commercial )
