I want to acknowledge Ken as well as Rob, thanks guys, you've both provided pretty definitive proof that something's amiss with my system perl.

Rob wrote:

I get something quite different:

That is very different indeed. Everything just worked the way it's supposed to. I noticed that it seems you are running your own locally-built perl: "/cygdrive/c/cygperl-5.40.0-d/bin/perl.exe". And Ken is running a locally built perl managed with perlbrew. I think my assignment for this weekend may be to build my own CygwinPerl.

You got the following g++ commandline:

g++  --shared  -Wl,--enable-auto-import -Wl,--export-all-symbols -Wl,--enable-auto-image-base -L/usr/local/lib -fstack-protector-strong  CSV_XS.o  -o blib/arch/auto/Text/CSV_XS/CSV_XS.dll  \
  /cygdrive/c/cygperl-5.40.0-d/lib/5.40.0/cygwin-thread-multi/CORE/cygperl5_40_0.dll -lpthread -ldl -lcrypt  \ 

The dangling backslash \ continue is in my output too, and is strange, but it is just an artifact that has nothing to do with my build failure.

Thanks again Rob.

G'day Soren,

I believe that I've warned you in the past about working directly with Cygwin's System Perl (/usr/bin/perl). If you update to the latest Cygwin Perl (v5.40.2), you'll get Text::CSV_XS version 1.60. I do Cygwin updates regularly; most recently was Friday evening (~24hrs ago).

$ /usr/bin/perl -Mstrict -Mwarnings -E '
    use Text::CSV_XS;
    say "Perl version: $^V";
    say "Perl location: $^X";
    say "Text::CSV_XS version: $Text::CSV_XS::VERSION";
    say "Text::CSV_XS location: $INC{q{Text/CSV_XS.pm}}";
'
Perl version: v5.40.2
Perl location: /usr/bin/perl
Text::CSV_XS version: 1.60
Text::CSV_XS location: /usr/lib/perl5/vendor_perl/5.40/x86_64-cygwin-t
+hreads/Text/CSV_XS.pm
[download]

I'm also reasonably certain that I recommended using Perlbrew. I updated to the lastest Perl (v5.42.0) this morning (~12hrs ago); I also installed the latest Text::CSV_XS from CPAN (version 1.61) along with many other modules.

Using Perlbrew to switch between Perl versions, and using the above code but starting with perl -Mstrict -Mwarnings -E (i.e. no /usr/bin/), here's the output using recent Perl versions:

Perl version: v5.38.0
Perl location: /home/ken/perl5/perlbrew/perls/perl-5.38.0/bin/perl

Consider leaving Cygwin's System Perl for Cygwin's use and start using Perlbrew for your own use and experimentation.

I'm fairly sure that solutions other than Perlbrew exist. I'm not familiar with these; perhaps another monk can advise you.

Ken, you are the person advocating for me to use perlbrew ;-) so I am going to toss this your way and ask if you have any suggestions. I had perlbrew installed for months but there was some initial trouble getting it to work and so I never built any perl using it. Today I tried again and unfortunately some tests failed:

I naturally went for the newest perl release, 5.42.0.:

perlbrew install -v -j 5 --switch --thread --multi --64all perl-5.42.0

Any ideas? Try with an older release maybe?

FWIW, I have no experience with Perlbrew. I don't see the point of it. I actually hate it - which is quite irrational (isn't all hatred ?) given that I've never tried it.
For mine, I just build perl in the normal way by running 'Configure', 'make test', 'make install' and finally 'make distclean' (in prepraration for the next build, of a different configuraton).

So, for my stock standard build of perl-5.42.0, I started with:
sh Configure -des -Dusethreads -Dusemultiplicity -Dprefix=/cygdrive/c/cygperl-5.42.0-d -Dlibpth=/lib/gcc/x86_64-pc-cygwin/11

For my -Duselongdouble build:
sh Configure -des -Dusethreads -Dusemultiplicity -Dprefix=/cygdrive/c/cygperl-5.42.0-ld -Dlibpth=/lib/gcc/x86_64-pc-cygwin/11 -Duselongdouble

And for my -Dusequadmath build:
sh Configure -des -Dusethreads -Dusemultiplicity -Dprefix=/cygdrive/c/cygperl-5.42.0-q -Dlibpth=/lib/gcc/x86_64-pc-cygwin/11 -Dusequadmath

I think I need that '-Dlibpth' switch only because I want the quadmath library to be automatically found for all 3 builds.
For you, I think that directive would end with "13" instead of "11", but I'm only guessing ... and it might even be the case that, with your gcc-13, there's no need for that directive any more.

I regularly hit a failing test in t/porting/exec-bit.t, and in one other file (I forget which).
My Cygwin installation is a few years old - your Cygwin might fare better.
Those couple of failures don't bother me at all, and I've not reported them.

I select which perl I want to use by running (eg):
export PATH=/cygdrive/c/cygperl-5.42.0-d/bin:$PATH

If I want to switch to a different perl I just run (eg):
export PATH=/cygdrive/c/cygperl-5.42.0-q/bin:$PATH

On cygwin I have (double, longdouble and quadmath builds) of perls 5.36.0, 5.38.0, 5.40.0, and 5.42.0.
It's easy to handle, and I'm not about to bother with perlbrew.
Of course, those who do want to use perlbrew for whatever purpose, are entitled to do so.

Cheers,
Rob

It's been quite a few years since I set up Cygwin & Perlbrew. I'll provide what information I can: some current and some quite old.

My current Win10 — what I see when I start cmd.exe:

Microsoft Windows [Version 10.0.19045.6159]
(c) Microsoft Corporation. All rights reserved.

C:\Users\ken>
[download]

My current system (Cygwin) information:

$ uname -a
CYGWIN_NT-10.0-19045 titan 3.6.4-1.x86_64 2025-07-15 07:55 UTC x86_64 
+Cygwin
[download]

I originally set up Cygwin using the installer on the Cygwin site; I have updated that many times over the years (currently at 3.6.4).

As far as I remember, I originally set up Perlbrew from the instructions on that page:

For a quick installation, do this:

\curl -L https://install.perlbrew.pl | bash
[download]

It would appear that I did this about six years ago and haven't changed it since:

$ which perlbrew
/home/ken/perl5/perlbrew/bin/perlbrew

$ ls -l /home/ken/perl5/perlbrew/bin/perlbrew
-rwxr-xr-x 1 ken None 1316905 Jul 26  2019 /home/ken/perl5/perlbrew/bi
+n/perlbrew
[download]

I've been installing Perl versions using instructions a little further down on that page. This is what I used yesterday.

To install the latest stable release ...

perlbrew install perl-5.42.0
perlbrew switch perl-5.42.0
[download]

This installed Perl v5.42.0 cleanly on the first run; no test or other errors.

I've also installed other Perl versions, stable & development, over the years:

$ perlbrew list
 * perl-5.42.0
   perl-5.40.0
   perl-5.39.3
   perl-5.38.0
   perl-5.36.0
   perl-5.34.0
   perl-5.33.5
   perl-5.32.0
   perl-5.30.0
[download]

I really can't help with the error information that you've posted. You may want to start (almost) from scratch:

1. Get Cygwin up-to-date. I do this by downloading the Cygwin Installer (setup-x86_64.exe) then running that from Win10: File Explorer.
2. Reinstall perlbrew using the instructions shown above.
3. Reinstall Perl v5.42.0 using the instructions shown above.

I'll also advise you to run the latest setup-x86_64.exe regularly — I generally aim to do this weekly so that it only takes some tens of minutes — otherwise you may find it takes hours if left for an extended period of time.

Good luck!

— Ken

When you're trying to do something in Cygwin -- whether it's installing the module in the Cygwin system perl or trying to run perlbrew to install another perl in Cygwin -- you need to make sure that your paths are all pointing where you think they are, and that they aren't pointing to a conglomeration of Strawberry and Cygwin locations.

echo $PATH
which perl
which cpan
which cpanm
which perlbrew
which gcc
perl -V
gcc -v
[download]

At this point, your intial post when asking for help with installing anything should include all that information (or the equivalent with cmd.exe's where or powershell's Get-Command, depending on which environment you are trying to use; I listed the linux-style which this time, since you're currently in the Cygwin environment), because otherwise the monks will waste their time assuming you have a sane setup, and only after half a dozen posts or more will it come out that there's interference between the two yet again.

I am curious why you have both Cygwin and Strawberry. It seems to me that you'd have a lot better luck in your perl module endeavors if you'd just pick one and become fluent in it. If there's a good reason, there's a good reason... but then you should consider figuring out how to keep the two completely separate from each other (make sure that your path in cmd.exe only shows Strawberry and nothing Cygwin, and that your path in Cygwin only shows its options and nothing from Strawberry).

G'day pryrt,

"I am curious why you have both Cygwin and Strawberry."

I don't know what Intrepid's reasons are but I don't think that situation is particularly unusual. I have a diverse collection of Perls for home and $work use:

• Cygwin System Perl — only used for demonstation purposes as in this thread.
• Perlbrew Perls (currently nine versions) sitting on Cygwin — used directly for home/personal use.
• Strawberry Perls (several versions; couldn't be bothered to count them) — used for some specific $work projects.
• ActivePerl (no longer used but it's still floating around somewhere) — was used for a specific $work project.
• And I ssh from Perlbrew Perls Cygwin (typically via bash scripts)^{[Updated: 14/8/25]} to a variety of $work Linux systems with their own Perl versions.

You're quite correct in that these need to be managed. I recall that I used to have some issues. I sorted all of this out many years ago and I now have no problems with this many Perl versions.

Hi, all. I just installed the CPAN module XS::Parse::Sublike using my system CygwinPerl and the build and test and install worked just as it ought to, and as it has before, many times, with XS (C-extension) modules being added on my system. The only difference I see with Text::CSV_XS is that it requires a call to g++ because C++ code is being used.

I understand the point you are making, pryrt, and I appreciate the advice. I will try to provide full information about my system in the future. I don't want to waste the monks' time or frustrate anyone.

You don't need to manually install Text::CSV_XS version 1.61 — just update Cygwin.

As I said last week, I typically update Cygwin weekly (usually on a Friday). Here's a reminder of the code I posted then:

$ /usr/bin/perl -Mstrict -Mwarnings -E '
    use Text::CSV_XS;
    say "Perl version: $^V";
    say "Perl location: $^X";
    say "Text::CSV_XS version: $Text::CSV_XS::VERSION";
    say "Text::CSV_XS location: $INC{q{Text/CSV_XS.pm}}";
'
Perl version: v5.40.2
Perl location: /usr/bin/perl
Text::CSV_XS version: 1.60
Text::CSV_XS location: /usr/lib/perl5/vendor_perl/5.40/x86_64-cygwin-t
+hreads/Text/CSV_XS.pm
[download]

When I updated Cygwin last Friday (i.e. 3 days ago) I noticed (amongst other changes) that Text::CSV_XS was updated to version 1.61 — here's what I get when I run the same code today:

$ /usr/bin/perl -Mstrict -Mwarnings -E '
    use Text::CSV_XS;
    say "Perl version: $^V";
    say "Perl location: $^X";
    say "Text::CSV_XS version: $Text::CSV_XS::VERSION";
    say "Text::CSV_XS location: $INC{q{Text/CSV_XS.pm}}";
'
Perl version: v5.40.3
Perl location: /usr/bin/perl
Text::CSV_XS version: 1.61
Text::CSV_XS location: /usr/lib/perl5/vendor_perl/5.40/x86_64-cygwin-t
+hreads/Text/CSV_XS.pm
[download]

I still recommend Perlbrew. ☺️

Update: The second block of code had the start of the command twice; probably a copy-paste error; fixed.
