Sidef and Perl (5.38.x) appear not to co-exist; or something weird

[kwolcott]

Hi;

I was successfully using Perl (downloaded from MacPorts, and also built from source) and then started using Sidef (found this via Rosetta Code).

Then something happened, I'm not sure what, I've lost the sequence of events, but I lost my Sidef installation (I had installed it via GitHub clone as described in the sidef-tutorial.pdf and sidef-book.pdf). Now when I try to install and run again I get the following error(s):

Can't load '/opt/perl/lib/5.38.2/darwin-2level/auto/Cwd/Cwd.bundle' for module Cwd: dlopen(/opt/perl/lib/5.38.2/darwin-2level/auto/Cwd/Cwd.bundle, 0x0001): symbol not found in flat namespace '_PL_curpad' at /opt/perl/lib/5.38.2/XSLoader.pm line 97.

BEGIN failed--compilation aborted at ./sidef.pl line 21.

I tried installed the Sidef module via cpanm, seems to be fine (in both Perl 5.38.x from MacPorts and Perl 5.40.x that I had built myself), but I really only know how to use Sidef (so far) by running the examples from Rosetta Code.

So I have the following bash script:

#!/bin/bash

wget https://github.com/trizen/sidef/archive/master.zip
unzip master.zip
cd sidef-master/bin/
./sidef -v

The bottom portion of the output of the aforementioned script:

inflating: sidef-master/utils/test_parser.pl

I have perl located at:
/opt/local/bin/perl
/opt/perl/bin/perl
/opt/perl5_40/bin/perl

What information have I not provided that will assist you in debugging my problem?

Thanks,

Hi!

Thanks for trying out Sidef.

There seems to be an issue with the Cwd Perl module. It may get fixed by reinstalling that module with cpanm:

cpanm --sudo --reinstall Cwd

Or by reinstalling/rebuilding Perl.

Thank you. None of these ideas seems to have any positive effect on the problem.

When I installed Perl 5.40.1 from source I ran the tests and there were no problems.

When I installed Perl 5.38.x from source quite some time ago, and ran the tests, there were no problems.

I think I will try building Perl 5.38.x from source and run the tests, but I don't think that doing that will show any problems.

Perhaps the MacPorts packaging of Perl5.38.x has a problem.

It is possible that since there is a mixture of Perl 5.34.x, Perl 5.36.x, Perl 5.38.x and Perl 5.40.1, that there are some conflicts (the first three are from MacPorts).

I will ask on the MacPorts mailing list.

Thanks,

I removed my locally installed from source versions of Perl.

I then installed Perl 5.40.1 from source, ran the tests, everything looks good.

I'm still unable to install Sidef as the standalone program.
