:@ Hi every body, i tried recently to compile some old C++ codes but regardless of the compiler i use i get the same error message when i want to link the *.obj file. i even tried it with Tlinker and macrolinker but with no success, if any one could help I'll be grateful, and it's kind of emergency.
these are the error messages:

Post at least the list of header fies included in your program and the user created header files, particularly the CHESS.H and CHESS.CPP file. Looks like there are some dependency issues with lack of necessary header files. Also indicate what compiler and OS you are using.

Good point, here is one of the projects, i also included some *.chr files for the fonts, so you can get them too (they are Persian fonts).
and i'm using windows xp and turbo c++ 3.1 and also 3.0 but they both give the same error, and i couldn't even make an exe file of the example bgidemo file that exists in them.

Have you tried anything like mingw (included with Code::Blocks or standalone) or Visual C++? All of the above are free and much much more recent (to put it politely).

EDIT: From the linker output it looks like you are using graphics.h. You may have to change some of your code to other libraries (e.g., nCurses and its variants) for it to be fully functional.
