Solving PAR::Packer "Can't locate loadable object for module IO in @INC"

Building an executable with Strawberry Perl is successful but when actually running it (after we have renamed the c:/strawberry to c:/strawberryX so it cannot find the dependencies from the path), fails with the following errors :

" Can't locate loadable object for module IO in @INC (@INC contains: CODE(0xa1d31c
) C:\strawberry\perl\vendor\lib .) at C:/strawberry/perl/site/lib/PAR/ l
ine 103
Compilation failed in require at C:/strawberry/perl/lib/IO/ line 266.
BEGIN failed--compilation aborted at C:/strawberry/perl/lib/IO/ line 26
Compilation failed in require at C:/strawberry/perl/lib/IO/ line 101.
BEGIN failed--compilation aborted at C:/strawberry/perl/lib/IO/ line
Compilation failed in require at C:/strawberry/perl/lib/IO/ line 133.
BEGIN failed--compilation aborted at C:/strawberry/perl/lib/IO/ line 133.
Compilation failed in require at -e line 351. "

I am on WinXP SP3 ,PAR 1.002,PAR::Packer 1.009, and have tried Strawberry Perl versions,, and the problem persists in all of them

perl -V reveals something strange with the backslashes:


"C:\strawberry\perl\vendor\lib" is not consistent with the other entries

I've found id 52794 which is related to the issue although it refers to version PAR::Packer 1.001;
nevertheless I got the following line :
"if ($Config{_delim} eq '\\') { s{\\}{/}g for @inc }"
from the patch (the patch actually REMOVES this line!!) and added it to after line 540.

I also corrected Strawberry's @INC by prepending the path  "C:/strawberry/perl/vendor/lib" by setting the PERL5LIB env variable, rebuilt it and everything works fine and even tried it in machines that have no Perl installation whatsoever

It looks like Strawberry has the path messed up and needs the correct one.

Furthemore "if ($Config{_delim} eq '\\') { s{\\}{/}g for @inc }" satisfies

Book Review : How To Create Pragmatic, Lightweight Languages

At last, a guide that makes creating a language with its associated baggage of lexers, parsers and compilers, accessible to mere mortals, rather to a group of a few hardcore eclectics as it stood until now.

The first thing that catches the eye, is the subtitle:

The unix philosophy applied to language design, for GPLs and DSLs"
What is meant by "unix philosophy" ?. It's taking simple, high quality components and combining them together in smart ways to obtain a complex result; the exact approach the book adopts.
I'm getting ahead here, but a first sample of this philosophy becomes apparent at the beginnings of Chapter 5 where the Parser treats and calls the Lexer like  unix's pipes as in lexer|parser. Until the end of the book, this pipeline is going to become larger, like a chain, due to the amount of components that end up interacting together.

The book opens by putting things into perspective in Chapter 1: Motivation: why do you want to build lan…

Deep Angel-The AI of Future Media Manipulation

Undeniably, we live in the era of media manipulation. Such powerful and accessible tools exist today that nearly everyone can do it. Now add to this collection Deep Angel, an artificial intelligence that can erase objects from photographs and videos.

I was notified of Deep Angel around the time I was watching Kill Switch, a futuristic and dystopic movie about our Earth getting cloned in order to suck the resources of the cloned planet, something that would sustain our world's energy needs for at least another millennium. To cut a long story short... full article on

SAP's Creating Trustworthy and Ethical Artificial Intelligence

With the ink hardly dry on the pages of the EU Ethical AI Guidelines manifest, a free online course exploring the issues they raise is already in prospect on the openSAP platform. Run by members of the very same group, the European Union’s High-Level Expert Group on Artificial Intelligence, who wrote the guidelines and in cooperation with SAP's online education platform, a course with the titleCreating Trustworthy and Ethical Artificial Intelligence has been made accessible to anyone with an interest on AI or ML:
