sgcoutts,

Maybe you have biblios compiled not with Win7, and this may be causing your problem. The solution could be to get the code for these bibliotecs and compile them at your machine.

You seem to be programming with C. If yes, I think you could try C# - also from VS - with ODBC connection. And may be you would have an easyer way to get your solution. From my point of view, C# is more user friendly - I know some C programmers donĀ“t like C#.

If I am wrong, excuse me.

Friendly,
Roberto Camargo.

Subject: [firebird-support] linker error in VS 2005



I am building an application with the firebird 2.5 API.  I keep getting the following errors at compile time.  I am using VS 2005 on win 7.

Error    1    error LNK2028: unresolved token (0A00004B) "extern "C" int __stdcall isc_print_status(int const *)" (?isc_print_status@@$$J14YGHPBH@Z) referenced in function __catch$??0Form1@CallSheet@@$$FQ$AAM@XZ$0    CallSheet.obj

Error    2    error LNK2028: unresolved token (0A00004C) "extern "C" int __stdcall isc_attach_database(int *,short,char const *,void * *,short,char const *)" (?isc_attach_database@@$$J224YGHPAHFPBDPAPAXF1@Z) referenced in function "public: __clrcall CallSheet::Form1::Form1(void)" (??0Form1@CallSheet@@$$FQ$AAM@XZ)    CallSheet.obj

Error    3    error LNK2019: unresolved external symbol "extern "C" int __stdcall isc_print_status(int const *)" (?isc_print_status@@$$J14YGHPBH@Z) referenced in function __catch$??0Form1@CallSheet@@$$FQ$AAM@XZ$0    CallSheet.obj

Error    4    error LNK2019: unresolved external symbol "extern "C" int __stdcall isc_attach_database(int *,short,char const *,void * *,short,char const *)" (?isc_attach_database@@$$J224YGHPAHFPBDPAPAXF1@Z) referenced in function "public: __clrcall CallSheet::Form1::Form1(void)" (??0Form1@CallSheet@@$$FQ$AAM@XZ)

here is the code snippet where i get the errors:

                #include <string>
                #include <stdio.h>
                #include <stdlib.h>
                #include "ibase.h"
                #include "ib_util.h"
                #include "iberror.h"

                ***

                db1 = initDBhandle(db1);
                param_buffer = populate_dpb("SYSDBA", "masterkey");
                db_pathname = "..\\CallSheet_DB\\CallSheet.fdb";
      try{                       isc_attach_database(status_vector,strlen(db_pathname.c_str()),db_pathname.c_str(),&db1, dpb_length, param_buffer);
                }
                catch(exception e){
                    if (status_vector[0] == 1 && status_vector[1]){
                        /* An error occurred. */
                        isc_print_status (status_vector);
                    }
                }


I have done extensive searching on the web for a solution to this.  Near as I can tell, I am missing an library file of some sort with the actual functions in them.
Any help would be greatly appreciated. If you need more info please ask

Thanks
