c++ - x64 上 Boost 1.60 和 VS 2013 的链接器错误

Question

#include <iostream>
#include <boost/timer/timer.hpp>

int main()
{
    boost::timer::auto_cpu_timer s;
    std::cout << "Hello World!" << '\n';
    return 0;
}

使用 msvc 12.0 x64 在 qt 中编译上面提到的代码并抛出以下错误:

libboost_timer-vc120-mt-gd-1_60.lib(cpu_timer.obj) : error LNK2019: unresolved external symbol "public: static class boost::chrono::time_point<class boost::chrono::steady_clock,class boost::chrono::duration<__int64,class boost::ratio<1,1000000000> > > __cdecl boost::chrono::steady_clock::now(void)" (?now@steady_clock@chrono@boost@@SA?AV?$time_point@Vsteady_clock@chrono@boost@@V?$duration@_JV?$ratio@$00$0DLJKMKAA@@boost@@@23@@23@XZ) referenced in function "void __cdecl `anonymous namespace'::get_cpu_times(struct boost::timer::cpu_times &)" (?get_cpu_times@?A0x0d396f6a@@YAXAEAUcpu_times@timer@boost@@@Z)
debug\Test.exe : fatal error LNK1120: 1 unresolved externals

Boost 已在架构 x86 和地址模型 64 中使用以下命令行参数进行编译-

b2 toolset=msvc-12.0 --prefix=<location> --build-type=complete --abbreviate-paths architecture=x86 address-model=64 install -j4

此外，程序在使用 32 位 msvc 2013 编译器编译时运行良好，我使用的是 Qt Creator。这是我的项目文件的内容 -

TEMPLATE = app
CONFIG += console c++11
CONFIG -= app_bundle
CONFIG -= qt

SOURCES += main.cpp


win32:CONFIG(release, debug|release): LIBS += "-LD:/boost/boost_1_60_0/stage/lib/" -llibboost_system-vc120-mt-1_60 -llibboost_filesystem-vc120-mt-1_60 -llibboost_timer-vc120-mt-1_60

我刚刚在 VS2015 中遇到了完全同样的问题。

我的解决方案是:

#include <boost/chrono.hpp>

希望这对其他人有帮助!
