Question

我创建了一个使用一些boost库的项目。最初该项目是使用MinGW创建的Eclipse项目，并且工作正常。现在我正在尝试将其转换为CMake项目。

我使用CMake准备MinGW makefile并尝试编译它但得到以下错误：

In file included from D:/Krzych/usr/local/include/boost/date_time/c_time.hpp:17:0,
                 from D:/Krzych/usr/local/include/boost/date_time/time_clock.hpp:16,
                 from D:/Krzych/usr/local/include/boost/date_time/posix_time/posix_time_types.hpp:10,

                 from D:/Krzych/usr/local/include/boost/asio.hpp:22,
                 from D:/Krzych/Projects/Picard/PicardDebugLink/include/CCommunicationAgent.h:22,
                 from D:\Krzych\Projects\Picard\PicardDebugLink\source\CCommunicationAgent.cpp:12:
c:\mingw\lib\gcc\mingw32\4.8.1\include\c++\ctime:65:11: error: '::difftime' has not been declared
   using ::difftime;
           ^
c:\mingw\lib\gcc\mingw32\4.8.1\include\c++\ctime:66:11: error: '::mktime' has not been declared
   using ::mktime;

对time.h中引用的ctime中的每个符号重复相同类型的错误。如您所见，boost date_time库直接包含ctime。

麻烦编译使用boost asio的项目
