c++ - 为什么 wxWidgets 不能与 Code::Blocks + minGW 一起工作？

Question

我如何使 wxWidgets 2.9.4 与 Code::Blocks + MinGW 一起工作？我已经构建了库(仅发布)并编写了一些代码。当我不使用事件表构建它时，它工作正常，但使用它们时，它会抛出错误。

这里是有事件表时构建消息的转储:

和另一个构建日志:

Code::Blocks 说这段代码是问题所在:

希望您能提供帮助，在此先感谢!

您需要始终将 DEBUG_FLAG=1 保留为 that，否则断言将无法编译。

这是 MSW 的 install.txt 中的内容:

Specifies the level of debug support in wxWidgets. Notice that this is independent from both BUILD and DEBUG_INFO options. By default always set to 1 meaning that > debug support is enabled: asserts are compiled into the code (they are inactive by default in release builds of the application but can be enabled), wxLogDebug() and wxLogTrace() are available and WXDEBUG is defined. Setting it to 0 completely disables all debugging code in wxWidgets while setting it to 2 enables even the time consuming assertions and checks which are deemed to be unsuitable for production environment.
