所以我有一个粒子光子嵌入板。我在 Windows 平台上设置了本地构建系统，使用 mingw，每个：https ://docs.particle.io/faq/particle-tools/local-build/photon/ 。最后，我真的很想使用来自 boost 库集的状态图库。

根据 boost statechart 库配置页面，即使禁用 RTTI 也应该可以使用它：http: //www.boost.org/doc/libs/1_65_1/libs/statechart/doc/configuration.html#GeneralConfiguration （RTTI在构建 makefile 中使用 -fno-rtti 禁用。正如人们所料。）

所以我在构建配置中添加了标志 -DBOOST_NO_RTTI 并确认它存在于编译命令中。

然而，在测试一个简单的“闪烁”应用程序时，其中包含了最简单的头文件：

#include <boost/statechart/state_machine.hpp>
#include <boost/statechart/simple_state.hpp>

使用构建命令：

导致错误列表，基本上推断不可能将库与 RTTI 一起使用。：

关于与 RTTI（或例外）一起使用的可能性，我在这里是否误解了一些东西？我了解所涉及的限制，只是想弄清楚如何构建应用程序。

如果不可能，那将是一种耻辱，这是一个不错的图书馆。

尝试添加-DNDEBUG到您的编译命令。

Boost Statechart需要在“调试模式”下编译时启用 RTTI：

调试模式编译选项

  • 必须打开 C++ RTTI（由各种断言使用）

您的错误消息来自 a ，因此我深入研究rtti_policy.hppBOOST_ASSERT的源代码以查找

struct id_provider
{
  const void * pCustomId_;
  #if defined( BOOST_ENABLE_ASSERT_HANDLER ) || !defined( NDEBUG )
  const std::type_info * pCustomIdType_;
  #endif
};

似乎 Statechart 检测您是否处于调试模式的方式是检查NDEBUG预处理器宏。
