[AlexDaniel]

Module Math::FFT::Libfftw3 cannot be installed (Fail), perhaps it has some failing tests.

• Tickets are opened/closed in this repo automatically (though not immediately).
• If you can install the module without any problems, add works for me label, leave a comment saying that it works for you and mention any details that you feel are important.
• If it needs a native library, put native dependency label, describe what you did to install it and ensure that same instructions are present in the README file of the module (otherwise submit a pull request). Also try to update this wiki page.
• If the module is broken, try to fix it and send a PR. Add PR sent label.
• If there is a problem in one of the dependencies, add failing dependency label and write a comment explaining the situation. Feel free to work on the corresponding ticket for the failing dependency.
• It is a good idea to assign yourself to this ticket if you're working on it (to make sure two or more people are not working on the same ticket at the same time).
• Once you are done, search for a next ticket.

If you can't self-assign yourself or attach a label, please let us know on #perl6 channel on freenode or just leave a comment here. We will try to give you privileges as fast as possible.

Yes, it depends on libfftw3.

[AlexDaniel]

Thanks! https://github.com/perl6/ecosystem-unbitrot/issues/389#issuecomment-461774685

[AlexDaniel]

Hold on a second! This is not an issue with a native dependency. Dependencies are installed correctly. This is a new problem in rakudo.

Math::FFT::Libfftw3 – Fail, Bisected: https://github.com/rakudo/rakudo/commit/ccf350e4bcf9a70f4038cb4259f82fc913dd87cd

[lizmat]

Looks to me this is an issue with a module using Rakudo Internals when they shouldn't ?

[MasterDuke17]

https://github.com/rakudo/rakudo/blob/master/lib/NativeCall.pm6#L600 perhaps?

[lizmat]

yeah, pretty much looks like that's the problem.

[lizmat]

Most likely fixed with https://github.com/rakudo/rakudo/commit/0d2658b806 , MasterDuke17++

[dogbert17]

It does indeed work:

dogbert@dogbert-VirtualBox ~ $ perl6 -v
This is Rakudo version 2018.12-293-gd904b70 built on MoarVM version 2018.12-94-g2eab275
implementing Perl 6.d.
dogbert@dogbert-VirtualBox ~ $ zef install Math::FFT::Libfftw3
