hey guys,

i hav being trying for a very long time to design a c++ programme that solves second order differential equations as a final year proj. I got some codes from the resource material i have been working with; i keep getting errors compiling the codes.

pls i need help debuging this errors. i use visual studio pro edition.

This is the error:


1>Code10.obj : error LNK2019: unresolved external symbol "double __cdecl parse(class ATL::CStringT<char,class StrTraitMFC_DLL<char,class ATL::ChTraitsCRT<char> > >,int,double * const,int * const)" (?parse@@YANV?$CStringT@DV?$StrTraitMFC_DLL@DV?$ChT raitsCRT@D@ATL@@@@@ATL@@HQANQAH@Z) referenced in function "public: void __thiscall CCode10::ODE1RK2(void)" (?ODE1RK2@CCode10@@QAEXXZ)

Your are declearing "double_cdecl" in header file
and not defining him or calling him in the .cpp file.

just do like

Code:

void double_cdecl ()
{

}

I didnt looked at your code im just guessing

Try putting you code in the post where you think the problem is and not attach your complete code.

Why is this posted as a poll?

Anyway, if you still want poll results, could you explain the difference between Visual C++ and native C++? What exactly is "native C++" in the context of Windows; unlike other OS's you don't usually get a bundled compiler as part of the OS.
