我的源代码没有用 Boost C++ 1.60 编译
$ g++ -c DateTimeUtil.cpp -I../../../boost_1.60.0/include/

这是我在源代码中包含的内容:
#include <boost/date_time/c_local_time_adjustor.hpp>
#include <boost/date_time/local_time_adjustor.hpp>
#include <boost/date_time/posix_time/posix_time.hpp>
系统信息:

$ g++ --version

最佳答案
只需首先包含此 header :
#include <boost/date_time/gregorian/gregorian_types.hpp>
关于c++ - Boost C++ 1.60 中的 `gregorian has not been declared` 错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/53435282/
