Visual C++ 2015 中的 CSpice：Link 个错误

Question

我正在尝试使用 Nasa 的 CSpice 工具包，但是当我尝试构建我的代码时，我收到类似

的错误

LNK2028 unresolved token (0A0004E6) "extern "C" void __cdecl spkpos_c(char const *,double,char const *,char const *,char const *,double * const,double *)"

我已经将库 (cspice.lib) 放入链接器中 Project Property page 并导入了 headers.
关于问题可能是什么的任何想法？

代码：

#include <iostream>
#include "stdafx.h"
#include "Calculation.h"
#include <ctime>
#include <string>
#include <sstream>

SpiceDouble* Calculation::sunPosition()
{   
//--Kernels--
//Load Earth data
furnsh_c("..\data\earth_pck\earth_latest_high_precision.bpc");
//Load LeapSeconds tabulation for time convertion
furnsh_c("..\data\all_spk\naif0011.tls.pc");
//Framework used is J2000, so it does not need to be loaded


//--Variables--
SpiceDouble epochTime;
SpiceDouble sunPosition[3];
SpiceDouble lightYears;

//--Calculation--
//Seconds past J2000 TDB
time_t t = time(0);
struct tm* utcNow = gmtime(&t);
std::string month;
switch (utcNow->tm_mon)
{
case 0:
    month = "JAN";
    break;
case 1:
    month = "FEB";
    break;
case 2:
    month = "MAR";
    break;
case 3:
    month = "APR";
    break;
case 4:
    month = "MAY";
    break;
case 5:
    month = "JUN";
    break;
case 6:
    month = "JUL";
    break;
case 7:
    month = "AUG";
    break;
case 8:
    month = "SEP";
    break;
case 9:
    month = "OCT";
    break;
case 10:
    month = "NOV";
    break;
case 11:
    month = "DEC";
    break;
}

std::stringstream format;
format << (utcNow->tm_year + 1900) << " ";
format << month << " " << utcNow->tm_mday << " ";
format << utcNow->tm_hour << ":";
format << utcNow->tm_min << ":";
format << utcNow->tm_sec;

ConstSpiceChar* et = format.str().c_str();
str2et_c(et, &epochTime);

//Get current sun position relative to earth, using earth as the inertia center
spkpos_c("sun", epochTime, "iau_earth", "none", "earth", sunPosition, &lightYears);
printf("%f", sunPosition);

return sunPosition;
}

解决了。

解决方案：库是 x64，Visual C++ 配置为 x86。 -> 运行 "vcvarsall.bat amd64" 在 cmd 中并将项目更改为构建 x64
