wxWidgets 和 boost::p roperty_tree 之间的冲突

Conflict between wxWidgets and boost::property_tree

本文关键字：之间 tree 冲突 roperty boost wxWidgets      更新时间：2023-10-16

我想在wxWidgets应用程序中使用boost：:p roperty_tree。

但是当我添加行时

#include <boost/property_tree/ptree.hpp>

到一个简单的wxWidgets，我突然得到编译错误：

这似乎表明 wxWidgets 方法无法再处理 UTF8 参数，转换为 UTF16 的能力已被 boost 头文件破坏。

似乎UNICODE定义不一致，即当 Boost 标头中包含 <windows.h> 时定义（或不定义），而当包含 wxWidgets 标头时未定义（或正在）。

为了防止这种情况发生，建议的解决方案是在 make 或项目文件中定义UNICODE，以便在命令行上定义它。您可能已经在那里定义了_UNICODE（如果使用 MSVS 项目），但这只会影响 CRT 标头，并且您也需要UNICODE才能<windows.h>。

找到了解决方法。 如果我在 wxWidgets 标头之后包含提升标头，则编译成功。
