Debian sid環境でGhosttyをbuild

matoken Debian・Linux・sid

com.mitchellh.ghostty

最近1.0.0がリリースされ話題になっているGhosttyというターミナルエミュレータがあります．最近Debian sid amd64環境のAlacrittyの上でNeovim+iBus Mozcで日本語入力時に遅延して?日本語が入力されて使い物にならないのもあり試してみようと思いました．(mltermだと大丈夫)

Debianで次回に動くバイナリは提供されていません．Ubuntuについては第三者がパッケージを提供されています．(apt sourcesは無い)

恐らくUbuntu版はDebianでも動作すると思いますがsourceからBuildしてみました．少し嵌ったのでメモしておきます．

手順は以下に書かれています．

関連パッケージの導入
$ sudo apt install libgtk-4-dev libadwaita-1-dev git
zigの導入
$ wget2 -c -v https://ziglang.org/download/0.13.0/zig-linux-x86_64-0.13.0.tar.xz \

Signature and comment signature verified
Trusted comment: timestamp:1717729444   file:zig-linux-x86_64-0.13.0.tar.xz     hashed
zigをfuse-archiveでmount(もしくはtar xfで展開)
$ fuse-archive ./zig-linux-x86_64-0.13.0.tar.xz
Ghosttyのsource入手
$ git clone https://github.com/ghostty-org/ghostty
$ cd ghostty
Note

fontなんかも同梱されていて結構サイズが大きく --depth=1 でもcloneに失敗するのでリモートでcloneしてrsyncしました．releasesのsource archiveから入手してもいいかもしれません．

zigにPATHを通してGhosttyのbuild
$ PATH=~/Downloads/zig-linux-x86_64-0.13.0/zig-linux-x86_64-0.13.0/:$PATH \
  zig build -Doptimize=ReleaseFast
$ ls zig-out/bin/ghostty
zig-out/bin/ghostty
Note

build時に以下のメッセージで数時間経っても進まなくなりました．Ctrl+cで中断して再度実行することで進みました．恐らく回線の問題．

Dupe, best guess currently is a GTK bug. Please search to find similar discussions (not issues).

GTKのbugではとのことですがUbuntu版があるのでそちらではどうなってるのだろうと.debを入手して試してみます．

Ubuntu向けGhosttyの.debを入手してarchiveをmountして実行

  1. 一番環境の近そうなUbuntu 22.10 amd64版を入手

  2. fuse-archiveでmount(もしくはunarコマンドなどで展開)

  3. fuse-archiveで適当な場所にdata.tarをmount(もしくはtar xfなどで展開)

  4. Ghosttyを実行

Ubuntu向けGhosttyは起動しました．
debian/patchesを覗くと1つpatchがありますが関係が無さそう．試しに 000-libbz2.patch を適用してみましたがやはり起動できません．
https://github.com/mkasberg/ghostty-ubuntu/tree/main/debian/patches

resetしてもとに戻して今度は debian/rules を参考に zig build を試しましたがこれも動作変わらず．
https://github.com/mkasberg/ghostty-ubuntu/blob/main/debian/rules

GhosttyのIssueを探すとまさにDebian sid amd64での回答がありました．
最近のpangoの更新で引っかかるようになったようです．以下のbuild optionを指定することで回避できるようです．

Upd: just build with -fsys=fontconfig parameter

— Pull requests · ghostty-org/ghostty
-fsys=fontconfig を付与してbuildし直し
$ PATH=~/Downloads/zig-linux-x86_64-0.13.0/zig-linux-x86_64-0.13.0/:$PATH \
  zig build -Doptimize=ReleaseFast -fsys=fontconfig
$ zig-out/bin/ghostty

動作するようになりました :)

ghostty debian sid

適当なPATHの通っている場所にcpしておく
$ rsync -av zig-out/* ~/usr/
$ which ghostty
/home/matoken/usr/bin/ghostty

ということで最近のDebian sid amd64環境などではしばらくはbuildオプションに -fsys=fontconfig を付けてあげる必要がありそうです．
