Hello, I''m switching over my project from OpenGL to directX 9 and I am having a problem using fstream.h (particularly an ifstream) in my project. I keep getting this error... D3dWrap error LNK2019: unresolved external symbol "void * __cdecl operator new(unsigned int,int,char const *,int)" (??2@YAPAXIHPBDH@Z) referenced in function "public: __thiscall ifstream::ifstream(void)" (??0ifstream@@QAE@XZ) I assume that I''m missing some library, but I can''t figure out which one it is. Does anyone know the solution to my problem?? Thanks Marcus Hays

Try using <fstream> instead of <fstream.h>.

What compiler and what implementation of STL are you using?

I solved the problem, the project hadn''t inherited the .lib''s it needed.

thanks
