Question

我遇到了与Boost相关的看似难以理解的编译错误，我已将其简化为包含单个boost头文件。在编译时（在Mac OS X 10.6.8上使用GCC 4.2），仅包含此文件的空文件包括：

#include "boost/date_time/posix_time/posix_time.hpp"

...生成这些错误：

这些Boost库被用作“仅标题” - 未构建。

任何线索？

问题出在文件<AssertMacros.h>中，它以某种方式被包含在内。

它定义了一个名为check的宏（和另一个名为require），它与“boost / type_traits / detail / has_binary_operator.hpp”中名为check的函数冲突。

您可以定义__ASSERTMACROS__以防止这种情况发生。

FWIW，在Mac OS X 10.7及更高版本中，Apple将这些宏重命名为__check等，以防止出现此问题。

包含单个boost posix_time.hpp标头时编译错误
