qtbindingsでwebviewを使う

Post date: 2018/07/28 10:22:43

というかqtwebkitをqtbindingsに組み込む。ubuntu 16.04ベース（多分）で実施。

apt-get install libqtwebkit-dev

qtbindignsは、最新版が4.8.6.5になっていた。

require 'Qt' のあとに、require 'qtwebkit'

2019/3/4追記 ubuntu 16.04へのqtbindings-4.8.6.4のインストール

ruby alta.rb

普通にインスチールしたら以下のエラー

ldd /opt/chef-workstation/embedded/lib/ruby/gems/2.5.0/gems/qtbindings-4.8.6.4/lib/2.5/qtruby4.so すると、以下が無いことがわかった：

以下をインストールすれば解決した：(apt-file search libsmokeqtcore.so.3 などしてわかった）

apt-get install libsmokeqt4-dev

apt-get install libqtruby4shared2
