我正在使用我已下载的预构建1.66（lib32-msvc-14.0）。我正在使用Visual Studio 2015。 我可以毫无问题地运行样本。 但是在我的项目中，只要我包含它（一个simle包装器），就会产生很多错误。
这是我的简单包装器：
Net.h：
#ifndef _PCNET_h
#define _PCNET_h
#include <cstdlib>
#include <cstring>
#include <iostream>
#include <boost/asio.hpp>
#include <string>
using boost::asio::ip::tcp;
typedef unsigned char byte;
typedef void(*newDataCallbackPtr)(byte cmd, byte *data, int len);
namespace net {
void init(std::string host, std::string port);
void send(byte cmd, byte *data, int len);
void registerCB(newDataCallbackPtr cb);
void join();
}
#endif
Net.cpp：
#include "Net.h"
const int max_length = 66000;
tcp::socket *s;
std::string delim = ";z|";
std::string recvData;
std::thread *t, *t2;
newDataCallbackPtr CB;
void readThrd();
//Public
void net::init(std::string host, std::string port) {
boost::asio::io_context io_context;
s = new tcp::socket(io_context);
tcp::resolver resolver(io_context);
boost::asio::connect(*s, resolver.resolve(host, port));
t = new std::thread([&io_context]() { io_context.run(); });
t2 = new std::thread(readThrd);
}
void net::send(byte cmd, byte *data, int len) {
byte *buff = new byte[len + 4];
buff[0] = cmd;
memcpy(buff + 1, data, len);
buff[len + 1] = ';';
buff[len + 2] = 'z';
buff[len + 3] = '|';
boost::asio::write(*s, boost::asio::buffer(buff, len + 4));
delete[] buff;
}
void net::registerCB(newDataCallbackPtr cb) {
CB = cb;
}
void net::join() {
t->join();
}
//Prv8
void readThrd() {
while (true)
{
size_t n = boost::asio::read_until(*s, boost::asio::dynamic_buffer(recvData), delim);
byte *buff = new byte[n - 3];
memcpy(buff, recvData.c_str(), n - 3);
recvData.erase(0, n);
CB(buff[0], buff + 1, (int)n - 4);
}
}
我的项目的其余部分编译没有任何问题。但是一旦我包含这个Net.h（在另一个.cpp中），编译器在winuser和asio头文件中给了我很多错误：

这里有什么想法吗？ 感谢。
