quantlib多個defininition：performCalculations（）const的」

我通過ubuntu16.04安裝升壓易於得到來自官方源安裝然後按照QuantLib quantlib多個defininition：performCalculations（）const的」

的安裝指南，然後我複製。其中一個quantlib示例（Examples/EquityOption）創建我自己的項目，我在testoption.cpp和testoption.cpp中創建一個類，現在我有三個文件（testoption.hpp，testoption.cpp和EquityOption.cpp）

in testoption.hpp

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

在EquityOption.cpp

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

在testoption.cpp

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

whre我把它和鏈接編譯成QuantLib，錯誤emessage彈出：

CMakeFiles/EquityOption.dir/ATestClass .cpp.o：功能boost::function1<double, double>::get_vtable() const': /usr/local/include/boost/math/special_functions/detail/igamma_large.hpp:69: multiple definition of QuantLib :: MultiCurveSensitivities :: performCalculations（）const' CMakeFiles/EquityOption.dir/EquityOption.cpp.o：/ usr/local/include/ql/experimental/termstructure s/multicurvesensitivities.hpp：106：首先在這裏定義 CMakeFiles/EquityOption.dir/ATestClass.cpp.o：在函數QuantLib::MultiCurveSensitivities::allZeros() const': /usr/local/include/boost/math/special_functions/detail/igamma_large.hpp:112: multiple definition of QuantLib :: MultiCurveSensitivities :: allZeros（）const' CMakeFiles/EquityOption.dir/EquityOption.cpp.o ：/usr/local/include/ql/experimental/termstructures/multicurvesensitivities.hpp：151：首先在這裏定義 CMakeFiles/EquityOption.dir/ATestClass.cpp.o：在函數QuantLib::MultiCurveSensitivities::sensitivities() const': /usr/local/include/boost/math/special_functions/detail/igamma_large.hpp:99: multiple definition of QuantLib :: MultiCurveSensitivities :: sensitivities（）const' CMakeFiles/EquityOption.dir/EquityOption.cpp.o：/usr/local/include/ql/experimental/termstructures/multicurvesensitivities.hpp：129：首先在此定義 CMakeFiles/EquityOption.dir/ATestClass.cpp.o：在函數中QuantLib::MultiCurveSensitivities::inverseSensitivities() const': /usr/local/include/boost/math/special_functions/detail/igamma_large.hpp:100: multiple definition of QuantLib :: MultiCurveSensitivities :: inverseSensitivities（）const' CMakeFiles/Eq uityOption.dir/EquityOption.cpp.o：/usr/local/include/ql/experimental/termstructures/multicurvesensitivities.hpp：134：此處首先定義 CMakeFiles/EquityOption.dir/ATestClass.cpp.o：在函數中QuantLib::MultiCurveSensitivities::allNodes() const': /usr/local/include/boost/math/special_functions/detail/igamma_large.hpp:101: multiple definition of QuantLib：：MultiCurveSensitivities :: allNodes（）const' CMakeFiles/EquityOption.dir/EquityOption.cpp.o：/usr/local/include/ql/experimental/termstructures/multicurvesensitivities.hpp：139：此處首先定義 collect2：error：ld返回1個退出狀態 CMakeFiles/EquityOption.dir/build.make：123：配方目標「EquityOption」失敗

我谷歌着，找一個類似的問題： Build error using head revision of rquantlib with head revision of QuantLib and boost 1.56 我嘗試的Why do I get a multiple definition error while linking?另一種解決方案，但˚F ailed。我對C++相當陌生，我是否還需要修改源頭文件以使內聯並重新編譯quantlib（在筆記本電腦上使用-j 4選項需要將近20分鐘）？

修改ql/experimental/terstrutures/multicurvesensitivities.hpp並且使類Multicurvesensitivities的成員函數內聯函數並複製到默認包含路徑（在ubuntu 16.04中它是/ usr/local/include/ql/experimental/terstructures）解決了問題。

確認。值得一提的是，這個問題在git倉庫中得到了解決。另一個解決方法（不管問題可能是個好主意）將不包括全局頭文件'ql/quantlib.hpp'，而只包含您需要的特定頭文件。這將進一步減少編譯時間。 –

另外，修改後運行'make'和'make install'可能比手工複製標題更安全。只有少數文件會受到影響並重新編譯，因此不會像原始編譯那樣長。 –
