Hi Joo Yang
you can see of the unresolved symbols, that the compiler recognized these functions as C++-functions and decorated them with type information.

There's an error in include file sqlcpr.h. You must put these lines into the top of the file :

#ifdef __cplusplus
extern "C" {
#endif

and to the bottom

#ifdef __cplusplus
#endif /* extern "C" { */
#endif

This way a C++-Compiler recognizes, that you want to use ANSI-C-functions and not C++.

Good luck
