Question

我的应用程序使用boost :: asio进行网络通信。问题是，当我启动应用程序时，我得到：

$('input[name='+i+'].errorField.apply-form-multi-select').css("color", "red");

在解码之后，这转化为：

undefined symbol: _ZNKSt9type_infoeqERKS_

经过大量挖掘，要知道代码中的实际被引用的位置，我将std::type_info::operator==(std::type_info const&) const添加到我的编译器标志中，导致编译时错误：

-Wl,--no-undefined

有关如何在错误中找到函数定义的任何建议吗？

编辑：

In function `boost::asio::ip::resolver_service<boost::asio::ip::tcp>& boost::asio::detail::service_registry::use_service<boost::asio::ip::resolver_service<boost::asio::ip::tcp> >()':
NetworkService.cpp:(.text._ZN5boost4asio6detail16service_registry11use_serviceINS0_2ip16resolver_serviceINS4_3tcpEEEEERT_v[boost::asio::ip::resolver_service<boost::asio::ip::tcp>& boost::asio::detail::service_registry::use_service<boost::asio::ip::resolver_service<boost::asio::ip::tcp> >()]+0x83): undefined reference to `std::type_info::operator==(std::type_info const&) const'

test.cpp是：

Boost version: 1.55
g++ (GCC) 4.1.2

g++ test.cpp -L$BIN/ -lcommunicationlayer -I/home/tmp/Boost1.55/boost_1_55_0

/bin/libcommunicationlayer.so: undefined reference to `std::type_info::operator==(std::type_info const&) const'
collect2: ld returned 1 exit status

使用boost :: asio对std :: type_info :: operator ==（std :: type_info const＆amp;）const的未定义引用
