#include <iostream>
#include <boost/timer/timer.hpp>
int main()

boost::timer::auto_cpu_timer s;
std::cout << "Hello World!" << '\n';

使用msvc 12.0 x64在qt中编译了上面提到的代码,它会抛出以下错误:
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)

Boost已在体系结构x86和地址模型64中编译,并带有以下命令行参数 -
b2 toolset=msvc-12.0 --prefix=<location> --build-type=complete --abbreviate-paths architecture=x86 address-model=64 install -j4
此外,使用32位msvc 2013编译器编译时程序运行正常,我正在使用Qt Creator.这是我的项目文件的内容 -
TEMPLATE = app
CONFIG += console c++11 …
