虚拟 noexcept(true) 错误：MinGW 和 gtkmm

Question

为了使用 MinGW 在 Windows 上构建一个 //working// C++/gtkmm-3.0 应用程序，我已经奋斗了一个月。我终于设法让库、MinGW 和 Codeblocks 在 Windows XP (VirtualBox) 上运行。但是，当我尝试构建时，出现以下错误。

这些是最新版本的 gtkmm-3.0 和依赖项。我通过 MSYS2 获得了它们，但由于未知原因我无法在该环境中构建。因此，正如经常推荐的那样，我将它们复制到 MinGW /lib 和 /include 目录，并确保 pkg-config 可以找到它们。那里一切都好（据说）。

这些问题显然不是我的代码引起的。我没有编写或修改 gtkmm。然而，我无法让这些消失。

值得一提的是，我最近收到与 "cannot find glib::ustring::ustring" 有关的错误，它决定停止抱怨，而是突然给我这些。如果之前的消息再次出现，我将 post 放在这里。

我开始觉得根本不值得在 Windows 上发布这个软件。

注意： 我得到了其中的 50 多个，都在 gtkmm-3.0 及其依赖库中，都来自 main 的第 1 行或第 2 行，并且都具有确切的同样的细节。我只会展示一些 space.

除了 gtkmm.

之外，在 Windows 上构建的其他稳定的、工作的项目和库似乎会弹出此类错误消息。

我最好的猜测 是我忘记了一些编译器标志、设置或构建过程中其他非常明显的步骤。赶紧提醒一下reader我在CodeBlocks(13.14)，所以那个build命令不是我自己写的

请求的信息 mingw32-g++.exe --version

mingw32-g++.exe (tdm-1) 4.7.1

这是与 CodeBlocks 13.14 捆绑在一起的版本。

...

我会赶紧提醒大家，我没有编写 gtkmm 或其依赖项的任何方面，这是所有这些错误的来源。此外，这是一个完全稳定的版本，而不是测试版或开发快照。其次，在我的 Linux 构建中，此完全相同的代码使用完全相同版本的库 。

也就是说，这是来自所请求位置的完整代码行。

C:/dev/MinGW/include/glibmm-2.4/glibmm/object.h，第 117 行

virtual ~Object() noexcept; //It should only be deleted by the callback.

C:/dev/MinGW/include/pangomm-1.4/pangomm/font.h，第 98 行

virtual ~Font();

Answer 1

你的 g++ 版本对于这段代码来说太旧了：4.7.x 有一个半生不熟的方法与显式和隐式异常规范的协调在继承的成员函数之间，在本例中是在虚拟函数之间 Glib::Object 和 Pango::Font.

的析构函数

您至少需要升级到 GCC 4.8.1 - 这恰好是 MinGW 的最新稳定版本。你可以得到最新的 Windows 来自 TDM 的 GCC 端口。最新的有 5.1

P.S。我有点怀疑你是否有 glibmm-2.4 和 pangomm-1.4 的构建真正同步。我有根据我的 linux 发行版 (Ubuntu 15.04)，这些包的来源都是官方的，我查询的样本问题声明的行号与你的不同，它们都没有 noexcept 规范肯定会避免障碍。
