在 Ubuntu 14.04 上使用最新的 Mono 4.3.0 和 GTK# 构建 Mono.Addins 失败
Fail to build Mono.Addins with the latest Mono 4.3.0 and GTK# on Ubuntu 14.04
正在尝试使用最新的 Mono 构建最新的 Monodevelop。我已经成功安装了 Mono 4.3.0 和 GTK#。如我所见，Monodevelop 需要安装 Mono.Addins，但是当我尝试安装最新的 Mono.Addins 时，它失败并出现以下错误：
Mono.Addins.Gui/AddinManagerDialog.cs(189,24): error CS0506: `Mono.Addins.Gui.AddinManagerDialog.Dispose()': cannot override inherited member `GLib.Object.Dispose()' because it is not marked virtual, abstract or override

Mono.Addins.Gui/HoverImageButton.cs(150,33): error CS0115: `Mono.Addins.Gui.HoverImageButton.OnExposeEvent(Gdk.EventExpose)' is marked as an override but no suitable method found to override
如何解决？
Ubuntu 版本 - 14.04
好的，我找到了解决方案。这很简单。我只是选择了错误版本的 GTK# 库。它应该是 2.12.* 版本，但在 GTK# master 上它是 2.99.*。当我更改版本时（通过 git checkout），所有内容都按应有的方式编译。
只有设置了标志 --disable-gui 和 --enable-gui-gtk3，Mono.Addins 才会使用 GTK# 的 2.99.* 进行编译。换句话说，GTK# 2.99.* 只能与 GTK+ 3.0 一起使用，因此 Mono.Addins 应该配置为使用这个版本的 GTK+。希望这个解释能对某人有所帮助。
