If you're encountering errors during the build process, try deleting your Bazel cache (located at ~/.cache/bazel by default).

sudo rm -rf ~/.cache/bazel/*

or

makepkg -osC
cd src/mozc/src
bazel clean --expunge
cd ../../..

sudo pacman -Rs fcitx-qt6 fcitx
makepkg -p PKGBUILD

The development of Fcitx has transitioned to Fcitx5, and Fcitx-Mozc is no longer maintained. Please try the following command.

sudo pacman -Rs fcitx5-qt fcitx5
makepkg -p PKGBUILD.fcitx

@fabiscafe Sorry for the delayed reply. It seems the download of Rust's llvm-tools isn't working properly. Please wait a while and try again. Alternatively, reinstalling Rust might resolve the issue.

We've also verified builds on Arch and Manjaro using the link below. The build itself should be possible, so please check it out. https://github.com/phoepsilonix/mozc-arch/releases

Sadly, I'm also unable to build it.

@phoepsilonix could you try to verify that it builds in a clean chroot?

git clone https://aur.archlinux.org/mozc-with-jp-dict.git
pkgctl build --repo extra mozc-with-jp-dict

should do that.

@jaro3

Tweaked. I think dict-to-mozc is now buildable for both gcc and clang. I think it can build on both ArchLinux and ManjaroLinux.

The “error: component download failed” is an error when communication with the rust server fails. In this case, try building again.

Also try deleting bazel's cache, as it may not be able to build due to bazel version upgrades.

If you still cannot build, please let us know the results of the following commands and the build environment. 

rustup target list --installed
rustup target list --installed | grep $(rustc -vV | sed -e 's|host: ||' -e 's|-gnu||p' -n) | grep -v musl && TARGET=$(rustup target list --installed | grep $(rustc -vV | sed -e 's|host: ||' -e 's|-gnu||p' -n)|grep -v musl|head -n1) || TARGET=$(rustup target list --installed | grep $(rustc -vV | sed -e 's|host: ||' -e 's|-gnu||p' -n)|grep musl|head -n1)
echo $TARGET

61.patch has been updated. Please delete 61.patch before building. This will ensure that the new 61.patch is re-downloaded.

@eagleflo

What are the CFLAGS and CXXFLAGS settings in makepkg.conf? In my environment, -U_FORTIFY_SOURCE is included, but I am able to build without any problem.
I am able to build with either gcc or clang.
-D_FORTIFY_SOURCE=1 and U_FORTIFY_SOURCE are set at the same time, which may be causing the error.

Should I ignore CFLAGS etc in makepkg.conf?

I have adjusted the _FORTIFY_SOURCE so that it is not set more than once. Adjusted to not use CFLAGS in makepkg.conf when using gcc.

eagleflo commented on 2024-01-24 18:12 (UTC)

This doesn't seem to build due to redefining _FORTIFY_SOURCE, somehow:

@hypnagogic

The Ruby script used to generate the dictionary was rewritten in Rust. An awk script to remove duplicate entries from the dictionary was also provided. The dependency on Ruby was completely removed. Instead, it relies on rustup.
