probuje napisac program, ktory bedzie wykrywal podlaczenie urzadzenia HID do portu usb... sciagnalem ddk... do pliku dodalem naglawek <hidsdi.h>, dodalem sciezki do folderow zawierajacych naglowki i biblioteki w ddk:

Code:

Tools -> Options->

Projects and Solutions -> VC++ Directories

->Executable Files

x:\WINDDK\3790.1830\bin            

->Include Files

x:\WINDDK\3790.1830\inc\wxp

->Library Files

x:\WINDDK\3790.1830\lib\wxp\i386

plik sie kompiluje bez problemu, jednak gdy chce zbudowac projekt to mam problem:

Code:

Linking...

usb.obj : error LNK2019: unresolved external symbol "unsigned char __stdcall HidD_GetAttributes(void *,struct _HIDD_ATTRIBUTES *)" (?HidD_GetAttributes@@YGEPAXPAU_HIDD_ATTRIBUTES@@@Z) referenced in function "int __cdecl bOpenHidDevice(void * *,unsigned short,unsigned short)" (?bOpenHidDevice@@YAHPAPAXGG@Z)

oczywiscie w opcjach projektu: Linker->Input->additional dependencies dodalem hid.lib...

gdzie moglem cos ominac/przegapic/popsuc;)??

Główny (widoczny) błąd polega na tym iż skompilowałeś swój kod jako cpp zamiast C.
Tip: zapisz plik jako usb.c i dodaj go do projektu, a .cpp usuń. Lub ewentualnie #include <hidsdi.h> ujmij w extern "C".

kurcze, nie myslalem, ze to moze miac az takie znaczenie... ale i tak sie nie udalo ;(...

gdy zrobie

Code:

extern "C" {

#include <hidsdi.h>

}

to bledy z linkowania sa takie:

Code:

Linking...

usb.obj : error LNK2019: unresolved external symbol __imp__SetupDiGetDeviceInterfaceDetailW@24 referenced in function "int __cdecl bOpenHidDevice(void * *,unsigned short,unsigned short)" (?bOpenHidDevice@@YAHPAPAXGG@Z)

usb.obj : error LNK2019: unresolved external symbol __imp__SetupDiDestroyDeviceInfoList@4 referenced in function "int __cdecl bOpenHidDevice(void * *,unsigned short,unsigned short)" (?bOpenHidDevice@@YAHPAPAXGG@Z)

usb.obj : error LNK2019: unresolved external symbol __imp__SetupDiEnumDeviceInterfaces@20 referenced in function "int __cdecl bOpenHidDevice(void * *,unsigned short,unsigned short)" (?bOpenHidDevice@@YAHPAPAXGG@Z)

usb.obj : error LNK2019: unresolved external symbol __imp__SetupDiGetClassDevsW@16 referenced in function "int __cdecl bOpenHidDevice(void * *,unsigned short,unsigned short)" (?bOpenHidDevice@@YAHPAPAXGG@Z)

D:\Program Files\Microsoft Visual Studio 9.0\Projects\usb\Debug\usb.exe : fatal error LNK1120: 4 unresolved externals

a gdy mam plik .c to jest tak:

Code:

Linking...

usb.obj : error LNK2019: unresolved external symbol __imp__SetupDiGetDeviceInterfaceDetailW@24 referenced in function _bOpenHidDevice

usb.obj : error LNK2019: unresolved external symbol __imp__SetupDiDestroyDeviceInfoList@4 referenced in function _bOpenHidDevice

usb.obj : error LNK2019: unresolved external symbol __imp__SetupDiEnumDeviceInterfaces@20 referenced in function _bOpenHidDevice

usb.obj : error LNK2019: unresolved external symbol __imp__SetupDiGetClassDevsW@16 referenced in function _bOpenHidDevice

D:\Program Files\Microsoft Visual Studio 9.0\Projects\usb\Debug\usb.exe : fatal error LNK1120: 4 unresolved externals

sprawdzilem dla wszystkich fukcji z bledow... nie mam tabelek, a pisza tak: Headers: Declared in setupapi.h. Include setupapi.h., wiec niewiele chyba...

i takie glupie pytanie... odnosnie katalogow jakie dodaje do "poszukiwania" bibliotek, czyli:
Code:
Tools -> Options->
Projects and Solutions -> VC++ Directories
->Executable Files
x:\WINDDK\3790.1830\bin
->Include Files
x:\WINDDK\3790.1830\inc\wxp
->Library Files
x:\WINDDK\3790.1830\lib\wxp\i386
bo nie wiem, czy to dobrze poustawialem... nie wiem tez, czy to ma znaczenie, ale procesor to amd athlon 64 i do tego windows xp (32bit) sp2...

EDIT:
problem rozwiazany... brakowalo jeszcze jednej biblioteki :/...

Zaznacz SetupDiGetDeviceInterfaceDetail i wciśnij F1. Zaczekaj cierpliwie na nowe okno, przewiń w dół do tabeli Requirements i zerknij co pisze w tabelce obok Library.
