If you're getting compilation errors, please delete your Bazel cache (~/.cache/bazel by default).

Build fails during installation for me with the following error:

 -> error making: mozc

I'm guessing some file directive could be edited to add the dependency declarations it is missing, but I'm not really a C or C++ expert, so I don't know what to do in this case: if it is an issue with the PKGBUILD or with the program's build script. If it is the later then I'm guessing it would be better to open an issue on GitHub instead? :)

@ruahcra Indeed; and when we're talking about an "old commit", we're really talking about a 3-year old version which still depends on deprecated stuff like gtk2 and python2 and a deprecated build procedure/system (for better or worse, upstream has switched out Ninja for Bazel since a few months ago).

Also, yeah, Mozc only releases new versions by commit (internally they're tagged as such and the version is incremented with almost each new commit, but there are no explicitly tagged releases) so it's up to the maintainer to keep up and update the package accordingly, just like with any other package really.

Regarding the UT dictionary, Mozc is the open source version of Google Japanese Input, which is a top-quality Japanese IME (along the lines of Google Keyboard et al). But Mozc being open source unfortunately means that it doesn't come with the extensive dictionaries/definitions that actually make Google Japanese Input what it is, because Google has chosen to keep them as closed source (possibly to hold an advantage over its competition). So what the UT dictionary does is bring the open source Mozc (closer) to the quality of its closed source cousin by patching the bundled dictionaries and expanding them.

There are some people that for whatever reason do not seem to care for the UT dictionary (or seemingly even for plain Mozc/IBus, seeing as even this vanilla package isn't part of the official Arch repos as IMHO it should) but as I said in the previous comment, I just now realized that since in my version of the packages Mozc has been split into its own base package, ibus-mozc-ut is actually nothing more but plain old ibus-mozc - the UT part only concerns the base Mozc package. So it could be made that there is only one version each of ibus-mozc, emacs-mozc, fcitx-mozc, fcitx5-mozc etc in the AUR, and two choices for the base Mozc part: mozc and mozc-ut, both of which the individual packages would be compatible with, and so the choice would be left to the user on whether to use UT or not. This way I think everybody would be happy.

So both packages build from the same upstream source, but apart from the additional dictionaries they include, the only difference is that this package is stuck on a old commit, where-as ibus-mozc-ut is using a more recent commit?

Also since mozc does not tag releases then it is up to the PKGBUILD maintainer to update the package at an appropriate commit in order to keep it up to date?

In that case I hope you are successful in getting ownership of this package! I will be moving to ibus-mozc-ut for the time being.

@CyberShadow Hmm, now that you mention it... There is of course the issue that my ibus-mozc-ut package includes the unofficial UT dictionary, so it's not a one for one replacement for the vanilla ibus-mozc, but since the base Mozc functionality (along with the UT inclusion) has been split into its own package, there really isn't anything that precludes merging them all into a family of interchangeable packages.

Well, back when I created my package I didn't want to step on anyone's toes (let alone @ponsfoot's, who'd been the de facto maintainer of the Mozc AUR packages for ages) but I think you're right, this probably calls for an orphan-and-adopt procedure. Thanks for the tip.

Nocifer, I think the appropriate procedure for this case is to submit a request to orphan this package and adopt it. If this package provides zero benefit over existing packages, then it could also be deleted, with the better packages having provides/replaces=mozc to provide an upgrade path.

Hey guys, I hope you all are aware that this package was last updated some 3 years ago and is currently unmaintained and severely out of date? I'm not usually one to tout my own horn, but there does exist an updated version in the AUR that is actively maintained (currently by me; that's the proverbial horn) and which solves the issues I see mentioned here, both the dependency on gtk2 (that's been deprecated and removed by upstream since ages ago, along with the python2 dependency) and the conflict between ibus-mozc and fcitx-mozc (you can have both installed on your system at the same time).

The updated package is ibus-mozc-ut. And again, because I dislike touting my own horn, let me just say that it's not like I stand to gain something by posting this "ad" here, it's just that the whole reason I created a new package in the first place was to spare people (myself included) from exactly the kind of issues reported in the comments here.

Just a friendly FYI.

please add gtk2 as a dependency? that fixed it for me aswell

Installing the gtk2 package resolved the build issue mentioned by @CyberShadow for me.

Seems to fail finding gtk+:

Missing dependency?
