MeCab

[AlexDaniel]

Module MeCab cannot be installed (AlwaysFail), 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.

@AlexDaniel
MeCab works well on travis ci environment: https://travis-ci.org/titsuki/p6-MeCab/builds/490520612
However, even if i set PERL6LIB=data/zef/lib,lib and run $ PERL6LIB=data/zef/lib,lib bin/blin.p6 MeCab, Blin cannot detect Zef::Fetch and fails.
Is there any good way to pass the build phase via Blin?

[AlexDaniel]

@titsuki if my understanding is correct, this is what happens. When Blin attempts to install a module, it constructs PERL6LIB paths specific to that module. So if a module depends on A and B, only A and B will be available. It does that by looking at depends and test-depends and build-depends fields.

Now, MeCab depends on Zef, right? However, Zef is not in any of the depends fields. So maybe just adding Zef to META6.json will make it installable?

[titsuki]

I have already fixed this problem but Blin requires the package list update (https://raw.githubusercontent.com/ugexe/Perl6-ecosystems/master/cpan1.json ) and it will take more time to show up the latest MeCab package.
So, I'll confirm this issue is really fixed or not tomorrow.

[titsuki]

I noticed that the package list has the latest MeCab package. I mistakenly understand Blin has Module:ver<VERSION> (e.g., MeCab:ver<0.11.0>) style syntax like Zef has.
However, MeCab:version<0.0.11> (i.e., the previous latest package) fails again due to the other missing libraries other than Zef::Fetch.
I'll test the next fixed version tomorrow.

@AlexDaniel
I tested two patterns to install the dependent modules that Zef provides:
https://github.com/titsuki/p6-MeCab/blob/0.0.13/META6.json#L6-L9
https://github.com/titsuki/p6-MeCab/blob/0.0.12/META6.json#L6-L14

However, MeCab still fails...
Are there any other solutions?

[AlexDaniel]

I think just adding "Zef" as a dependency should work, I don't know why it doesn't… I'll try to take a look later. Anyway, I'm pretty sure for most users this is not an issue, I think currently it only fails in Blin.
