Gershwin-desktop-legacy and Workspace Japanese Localization

Gershwin-desktop-legacy は gnustep desktop system です。
GitHub - gershwin-desktop-legacy/system: Gerswhin System · GitHub

この system では libobjc2 が使え、gnustep の CoreAnimation (libs-quartzcore) が
エラーなく動作します。
OSはLubuntu を使用しています。README に書いてある Installation for Debian
の方法で問題なくインストールできました。
ターミナルからWorkspaceコマンドで起動します。

Workspace 起動画面（アイコン表示に変更している）

日本語の設定
起動直後は、日本語フォントの設定がされていません。メニュー等に「??」などが
表示されていると思います。
SystemPreferences の Font から日本語フォントを設定します。
"Noto Sans CJK JP" を使用しています。

日本語化
フォントを設定をしても、まだ英字や「??」が残ります。
gorm ファイル、Localizable,strings、m クラスファイル等を変更して新たに
日本語化しました。これらのファイルは、
https://github.com/tomohonaga/gworkspace_jp
にあります。

GhostBSD New Release 25.02-R14.3

GhostBSD の新バージョン GhostBSD 25.02-R14.3 p2 がリリースされました。
ghostbsd.org
このバージョンから、Community Images に Gershwin が加わりました。
Gershwin は GNUstep-base の desktop 環境です。
今のところPreview版です。
(Downloadページ)

VirtualBox にインストールしてみました。実機では、メインメモリは8GBが必要
です。VirtualBoxでは5GB以上で起動できます。

前回に続き OpenGLView の記事です。
gles3 https://github.com/craff/gles3 のプロジェクト内の examples に
rotating cube があります。
これを NSOpenGLView で描画してみました。

[実行結果]

cube の回転には NSTimer を用いています。
