Boost Statechart库可以与粒子光子嵌入式系统一起使用吗

Question

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

根据 boost 状态图库配置页面，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 在带有 -fno-rtti 的构建 makefile 中被禁用。正如人们所期望的那样。）

所以我将标志 -DBOOST_NO_RTTI 添加到构建配置并确认它存在于编译命令中。

然而，在测试包含最简单的头文件的简单 'blinkled' 应用程序时：

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

使用构建命令：

导致错误列表，基本上推断无法将库与 RTTI 一起使用。:

关于与 RTTI（或例外）一起使用的可能性，我是否误解了这里的某些内容？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。

尝试将 -DNDEBUG 添加到您的编译命令中。

提升状态图requires RTTI to be enabled when it's compiled in "debug mode":

Debug mode compilation options

C++ RTTI must be turned on (used by various asserts)

你的错误信息来自BOOST_ASSERT，所以我深入rtti_policy.hpp的源代码找到

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

Statechart 检测您是否处于调试模式的方式似乎是通过检查 NDEBUG 预处理器宏。
