我被这个问题毁了......实际上我想在ruby中运行Real多线程...我已经编写了一个在ruby中使用GTk的应用程序......现在我想将该应用程序移植到JRuby。 ....

请帮助我......任何人在＆gt;＆gt;之前都做错了吗？提前致谢

Answer 1

这里的错误是你要么没有安装C编译器，要么就是找不到它

IOError：无法运行程序“cc”

所以看起来GTK正在尝试构建原生扩展，这在Jruby中得不到很好的支持。这篇博客文章讨论了他编写的一些代码，用于使用来自Jruby https://wordpress.kaspernj.org/?p=85

的gtk +

由于您正在移植到Jruby，您也可以直接使用Java GTK或直接使用SWT。 SWT https://github.com/danlucraft/swt有一个宝石，其中包括一些简单的例子，不知道它有多完整。

作为旁注，Redcar Editor是用Jruby + SWT编写的

Answer 2

你可以试试Gtk3的FFI绑定。我自己使用过普通的Ruby和JRuby。宝石名为“gir_ffi”和“gir_ffi-gtk”。

然而，你知道，目前在MRI Ruby下存在一些线程问题，你必须自己解决这个问题，就像我在这里做的那样：

https://github.com/kaspernj/gtk3assist/blob/master/lib/gtk3assist_threadding.rb

此库基本上是直接从C库中提取的，因此比普通的Ruby GTK库复杂得多。我试图让它变得更简单，但要使其像Ruby GTK2库一样简单易行，还有很长的路要走：

https://github.com/kaspernj/gtk3assist/tree/master/lib

这可能是我们一直在等待的多Ruby和多操作系统GUI库:-)我已经在Linux和Mac下工作了（还没有在Windows上试过）。
