使用<intrin.h>中的__cpuid（）時出現鏈接錯誤？

Question

錯誤說：

error LNK2019: unresolved external symbol WinCPUID_Init referenced in function 
"public: static void __cdecl CCapturer::GetCPUVendorId(void)" 
(?GetCPUVendorId@CCapturer@@SAXXZ) 

，但它並沒有指出我應該在MSDN _cpuid

添加哪些LIB如何解決呢？

Answer 1

見我的回答你的問題在這裏：http://social.msdn.microsoft.com/Forums/vstudio/en-US/b80068ac-e17b-4f21-85fd-1d87fdc9b6b6/link-error-when-using-the-cpuid-in-intrinh?forum=msbuild

Answer 2

顯然它也使用fddshow，試用安裝程序（我不知道那是什麼），並在WinCPUID.dll

external  'WinCPUID_Init@files:WinCPUID.dll cdecl'; 

定義我發現WinCPUID_Init符號匹配的位置：

http://code.google.com/p/notepad2-mod/source/browse/branches/inno/distrib/cpu_detection.iss?r=616

代碼頭說

// The script is taken from the ffdshow-tryouts installer 
// http://sourceforge.net/projects/ffdshow-tryout/ 

後來

// functions to detect CPU 
function WinCPUID_Init(msGetFrequency: Integer; var pInfo: TCPUInfo): Integer; 
external  'WinCPUID_Init@files:WinCPUID.dll cdecl'; 
// function to get system information 
procedure GetSystemInfo(var lpSystemInfo: TSystemInfo); external 'GetSystemInfo@kernel32.dll stdcall'; 


procedure CPUCheck(); 
var 
    CPUInfo: TCPUInfo; 
begin 
    WinCPUID_Init(0, CPUInfo); 

    if (CPUInfo.bIsInitialized = 0) then begin 
    // something went wrong 
    end 
    else begin 
    if (CPUInfo.bSSE_Supported = 1) then begin 
     cpu_sse := true; 
    end; 
    if (CPUInfo.bSSE2_Supported = 1) then begin 
     cpu_sse2 := true; 
    end; 
    end; 
end;
