Question

我有一段代码使用了boost的unordered_set

#include <boost/unordered_set.hpp>
boost::unordered_set<string> mySet(100);

它在unix下用gcc编译并正常工作。当我尝试使用mingw32（gmake 3.8.1）进行交叉编译时，我收到以下消息：

/usr/i686-pc-mingw32/sys-root/mingw/include/boost/cstdint.hpp:114: error: declaration does not declare anything

对我而言，它似乎与模板相关的问题;有什么建议吗？

谢谢你，马蒂亚

其他提升功能可用，例如词汇演员

#include <boost/lexical_cast.hpp>

似乎某些typedef会破坏boost cstdint标头，看起来像

103   using ::int8_t;
104   using ::int_least8_t;
105   using ::int_fast8_t;
106   using ::uint8_t;
107   using ::uint_least8_t;
108   using ::uint_fast8_t;

在我的系统上。所以，有些英雄可能会定义“#define uint8_t”而不是“typedef ... uint8_t”，因此这段代码会中断。

您可能会尝试修改您的boost / config / platform / win32.hpp，如果有帮助，请将错误报告给mingw开发人员。
