problem with matrix class

[tinou35]

Hi,
i'm new user of quantlib.
I'm trying to use the matrix class of quantlib. When i create matrix, there are no problem. but when i try to change an element inside on of them such as :

Matrix M1 = Matrix(1,1,1);
M1[0][0]=1.0;

I have the following result, and i haven't any idea of how to solve it.

test.obj : error LNK2019: symbole externe non résolu "public: __thiscall QuantLib::Error::Error(class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > const &,long,class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > const &,class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > const &)" (??0Error@QuantLib@@QAE@ABV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@J00@Z) référencé dans la fonction "public: double * __thiscall QuantLib::Matrix::row_begin(unsigned int)" (?row_begin@Matrix@QuantLib@@QAEPANI@Z)
test.obj : error LNK2001: symbole externe non résolu "public: virtual char const * __thiscall QuantLib::Error::what(void)const " (?what@Error@QuantLib@@UBEPBDXZ)

thx

It's a linker error. How did you compile QuantLib, and how are you
compiling/linking your program?

I use visual C++ 2005.
the main problem is the constructor of matrix works, (i can create a matrix full of 1 for instance) but i can't use some functions inside the same class such as M[1][1]=1;

thx

What is the error message you get?
