链接到 Boost 系统时出错
Errors linking to Boost system
我为 MinGW 4.9.2 32 位构建了 Boost 1.59,如下所示:
bootstrap.bat mingw
b2 --prefix=%USERPROFILE%\Code\Libraries\boost toolset=gcc install
(这些是静态库)
尝试编译时:
#include <iostream>
#include <boost/asio.hpp>
#include <boost/date_time/posix_time/posix_time.hpp>
using namespace std;
int main()
{
boost::asio::io_service io;
boost::asio::deadline_timer t(io, boost::posix_time::seconds(5));
t.wait();
cout << "Hello World!" << endl;
return 0;
}
有:
g++ -o test -L %USERPROFILE%\Code\Libraries\boost\lib -l boost_system-mgw49-mt-1_59 -I %USERPROFILE%\Code\Libraries\boost\include\boost-1_59 main.cpp
我收到这个错误:

我在两台计算机上都遇到了同样的错误。感谢您的帮助!
这是一个 link 错误。您需要 link 到 Boost System 库。
这样做
g++ -o test -L %USERPROFILE%\Code\Libraries\boost\lib -lboost_system -I %USERPROFILE%\Code\Libraries\boost\include\boost-1_59 main.cpp
