I made UDFs in vC++ and loaded them on windows binary version of mysql..
They are working perfectly fine
.I think you should specify these following arguments while defining a
function
e.g.
double func_test(UDF_INIT *initid, UDF_ARGS *args, char *is_null,
char *error)
{
return 1.0;
}
now try this..
