マリオ／ゼビウスの背景配置ツールをRuby+QT4で試す

2023/08/19 16:00:00

Program

Wsl, Ubuntu, Game

ubuntu20.04 on wsl2 環境で試す #

wsl2 + ubuntu20.04 + ruby + qt4 で背景配置ツールを動作させてみる。
tilemapエディタは大昔に自作したやつで試す。
ruby から qt4 を動作させるには qtbindings を利用する必要があるが、
qtbindings 公式サイトを見ると、ruby 2.5.x + qt4 が最後のサポートらしい。。。

qtbindings 公式
https://github.com/ryanmelt/qtbindings
自作の背景配置ツール一式
tilemap_editor ディレクトリが対象)
https://github.com/oya3/ruby_tools

以下の手順は、wsl2 + ubuntu20.04 + rbenv の環境が構築済みであることが前提
開発環境はバージョンが違うが以下が参考になるはず。 ubuntu22.04開発環境構築

$ sudo apt install cmake
$ sudo add-apt-repository ppa:rock-core/qt4
$ sudo apt install qt4-default

# ruby_tools を取得
$ git clone https://github.com/oya3/ruby_tools
# qt4 サンプルに移動(ruby 2.5.8用)
$ cd ruby_tools/tilemap_editor

# ruby 2.5.8 インストール
$ rbenv install 2.5.8

# bundler インストール。が失敗する
$ gem install bundler

Your RubyGems version (2.7.6.2) has a bug that prevents `required_ruby_version` from working for Bundler. Any scripts that use `gem install bundler` will break as soon as Bundler drops support for your Ruby version. Please upgrade RubyGems to avoid future breakage and silence this warning by running `gem update --system 3.2.3`

# 時間がかかるが成功するはず。
# 実行
$ bundle exec ruby main.rb

ubuntu22.04 on wsl2 環境で試すが動作せず #

ubuntu22.04 環境でも試してみたが、セグメンテーションフォルトが発生して起動させることができない。。。
ubuntu20.04 では実施していなかった enable-shared オプションを有効にしてrubyをインストールしても状況変わらず。

RUBY_CONFIGURE_OPTS=–enable-shared rbenv install 2.5.8

また、以下を実施後にqt4-default をインストールしてもダメだった。

sudo apt install libxcb-xinerama0 libglu1-mesa-dev

$ sudo apt install cmake
$ sudo add-apt-repository ppa:ubuntuhandbook1/pp   # <--- ここは ubuntu20.04 と違うので注意
$ sudo apt install qt4-default

# ruby_tools を取得
