Does fcitx4-mozc support Bazel build?

[utuhiro78]

Hello,

Mozc developers wrote "new targets will be supported by Bazel only". I could build fcitx5-mozc with Bazel (Thanks Nocifer), but I couldn't build fcitx4-mozc. I'm using Arch Linux (gcc-11.1.0).

Did you test Bazel build for fcitx4-mozc?

mkdir mozc_tmp
cd mozc_tmp/
git clone --depth=1 --recurse-submodules --shallow-submodules https://github.com/fcitx/mozc.git
cd mozc/
sed -i -e 's/x86_64-linux-gnu\/qt5/qt/' src/config.bzl
cd src/

env PATH="/usr/lib/jvm/java-11-openjdk/bin/:$PATH" bazel build server:mozc_server gui/tool:mozc_tool unix/fcitx:fcitx-mozc.so unix/icons --config oss_linux --compilation_mode opt

[utuhiro78]

I added error message. Thank you for developing Fcitx.

I found the article wirtten by Hiroyuki Komatsu (a developer of Mozc). https://zenn.dev/komatsuh/articles/d6844edd398402

The first character is not entered in Chrome This is not a Mozc issue in most cases If you are using fcitx, change it to fcitx5. It will solve the problem in many cases

He is testing fcitx and fcitx5!

[utuhiro78]

I close this issue and test fcitx4-mozc another way.

[wengxt]

Please give it a try, it should be fixed.

Thanks wengxt! It works fine.

I uploaded PKGBUILD files for fcitx4-mozc/fcitx5-mozc. https://osdn.net/users/utuhiro/pf/utuhiro/dl/fcitx-mozc-ut-bazel-20211009.PKGBUILD https://osdn.net/users/utuhiro/pf/utuhiro/dl/fcitx5-mozc-ut-bazel-20211009.PKGBUILD https://osdn.net/users/utuhiro/pf/utuhiro/files/

I don't know about Bazel, so I thought I was wrong.
