c++ - "QuantLib::MulticurvesSensitivities:performCalculations() const'的quantlib多重定义

我通过官方来源的apt-get install在ubuntu16.04上安装了boost。
然后按照QuantLib 的安装指南进行操作

然后我复制一个quantlib示例(Examples / EquityOption)以创建自己的项目，在testoption.cpp和testoption.cpp中创建一个类，现在我有三个文件(testoption.hpp，testoption.cpp和EquityOption.cpp)

在testoption.hpp中

#ifndef TESTOPTION_HPP
#define TESTOPTION_HPP
#include <ql/quantlib.hpp>
using namespace QuantLib
class testOption{
//class declaration
};
#endif

在EquityOption.cpp中

#include <ql/quantlib.hpp>
#include "testoption.hpp"
int main(int, char* [])
{
//some code here
}

在testoption.cpp中

#include "testoption.hpp"
//definition of member function in testOption

当我编译它并链接到QuantLib时，弹出错误消息:

我四处搜寻，发现了一个类似的问题:
Build error using head revision of rquantlib with head revision of QuantLib and boost 1.56
我尝试了Why do I get a multiple definition error while linking?的另一种解决方案，但失败了。
我对C++还是很陌生，是否还需要修改源头文件以使其成为嵌入式方法并再次编译quantlib(在我的笔记本电脑上使用-j 4选项需要近二十分钟)？

最佳答案

修改ql / experimental / terstrutures / multicurvesensitiveivities.hpp并使Multicurvesensitiveivities类的成员函数内联函数并复制到默认包含路径(在ubuntu 16.04中，它是/ usr / local / include / ql / experimental / terstructures)解决了该问题。
