提升未定义的引用交叉编译linux到windows

Question

我正在尝试使用 boost 从 linux 交叉编译到 windows。我已经交叉编译了 boost 并且我确实有 DLL，但是当我链接时，我得到了几个未定义的引用：

src/client/CommunicationHandler.o:CommunicationHandler.cpp:(.text+0x170): 对`boost::asio::io_service::io_service()'的未定义引用

src/client/CommunicationHandler.o:CommunicationHandler.cpp:(.text+0x1b7): 对 boost::asio::ip::address_v4::from_string(std::__cxx11::basic_string, std:: 的未定义引用分配器 > const&)'

src/client/CommunicationHandler.o:CommunicationHandler.cpp:(.text+0x1c7): 对 boost::asio::ip::address::address(boost::asio::ip::address_v4 const& 的未定义引用)'

src/client/CommunicationHandler.o:CommunicationHandler.cpp:(.text+0x54e): undefined reference to `boost::asio::io_service::~io_service()'

src/client/CommunicationHandler.o:CommunicationHandler.cpp:(.text+0x5c0): undefined reference to `boost::asio::io_service::~io_service()'

src/client/CommunicationHandler.o:CommunicationHandler.cpp:(.text+0x97e): 对`boost::asio::io_service::run()'的未定义引用

src/client/CommunicationHandler.o:CommunicationHandler.cpp:(.text$_ZN5boost4asio2ip14basic_endpointINS1_3tcpEEC1ERKNS1_7addressEt[_ZN5boost4asio2ip14basic_endpointINS1_3tcpEEC1ERKNS1_7addressEt]+0x2a): 对 boost::asio::ip::boost:::endpoint 的未定义引用asio::ip::address const&, unsigned short)'

的src /客户端/ CommunicationHandler.o：CommunicationHandler.cpp :(文本$ _ZN5boost4asio2ip16resolver_serviceINS1_3tcpEE7destroyERSt10shared_ptrIvE [_ZN5boost4asio2ip16resolver_serviceINS1_3tcpEE7destroyERSt10shared_ptrIvE] + 0×20）：未定义参照升压:: ASIO ::详细:: resolver_service_base ::破坏（STD :: shared_ptr的＆）”

...等

为什么符号不在 DLL 中？我该怎么做才能使其正确链接？

Answer 1

这使它起作用

#ifndef BOOST_SYSTEM_USE_LIB # 定义 BOOST_SYSTEM_USE_LIB #endif
