Hi Paulo,
The problem you are seeing is due to name-mangling in C++. All C++ functions get decorated with their argument types (typically). This causes grief if some of the modules are written in C.
Wrap the header for SQLLIB functions ( I am not sure of the filename on your port) within an extern "C" wrapper. In fact, you must resort to this whenever you include prototypes for any C functions in a C++ file. You must also wrap any defined variables and functions within the C++ file in extern "C" wrappers if these are to be seen by other .C files.
e.g.
<-------------- The C++ file --------------------->extern "C"
{
#include <sqllib header>
#include <prototype for other C functions> }
extern "C"
{
int my_c_var ;
}
<-------- the .C file -------------------------->
