我在Qt creator上使用boost lib开发应用程序,我的平台是
Windows8 MSVC2013 64.
每个我有两个类我使用boost标头,
现在我需要使用这个类,当我从另一个源文件包含这些类头时,我收到错误
error WinSock.h has already been included
#define WIN32_LEAN_AND_MEAN #include <boost/asio.hpp> #include <boost/asio/deadline_timer.hpp> #include <boost/asio/io_service.hpp> #include <boost/asio/ip/tcp.hpp> #include <boost/asio/read_until.hpp> #include <boost/bind.hpp> #include <boost/asio/streambuf.hpp> #include <boost/asio/write.hpp> #include <boost/asio/read.hpp> #include <boost/asio/placeholders.hpp> #include <boost/foreach.hpp> #include <boost/property_tree/ptree.hpp> #include <boost/property_tree/json_parser.hpp> #include <boost/foreach.hpp> #include <boost/thread/thread.hpp> #include <boost/thread/thread_time.hpp> #include <boost/interprocess/ipc/message_queue.hpp> #include <boost/interprocess/sync/interprocess_semaphore.hpp> #include <boost/bind.hpp> #include <boost/cstdint.hpp> #include <boost/circular_buffer.hpp> #include <boost/format.hpp> #include <boost/algorithm/string/split.hpp> #include <boost/algorithm/string/classification.hpp>
在第二节课中,我以同样的方式使用了标题
#define WIN32_LEAN_AND_MEAN #include <iostream> #include <boost/property_tree/ptree.hpp> #include <boost/property_tree/json_parser.hpp> #include <boost/foreach.hpp> #include <boost/thread/thread.hpp> #include <boost/thread/thread_time.hpp> #include <boost/interprocess/sync/interprocess_semaphore.hpp> #include <boost/interprocess/ipc/message_queue.hpp> #include <boost/asio/deadline_timer.hpp> #include <boost/asio/io_service.hpp> #include <boost/asio/ip/tcp.hpp> #include <boost/asio/read_until.hpp> #include <boost/asio.hpp> #include <boost/bind.hpp> #include <boost/asio/streambuf.hpp> #include <boost/asio/write.hpp> #include <boost/asio/read.hpp> #include <boost/bind.hpp> #include <iostream> #include <boost/asio/placeholders.hpp> #include <fstream> #include <boost/cstdint.hpp> #include <boost/circular_buffer.hpp> #include <boost/format.hpp> #include <boost/algorithm/string/split.hpp> #include <boost/algorithm/string/classification.hpp>
我已经在Boost::asio winsock and winsock 2 compatibility issue找到了答案,但我仍然遇到了问题.
编辑：
我的第二个内部使用第一个类头,这是多次包括升级头的原因吗？
我已经将boost头包括在内了
#ifndef class_obj__1 #define class_obj__1 //boost headers //boost headers #endif
任何帮助将不胜感激.
谢谢

解决方法
将#define WIN32_LEAN_AND_MEAN移动到g命令行参数列表为-DWIN32_LEAN_AND_MEAN.这对我有帮助. 还有一件事帮助我重新排序#include指令,将boost包括在所有其他指令之前.
