c++ - 从 32 位 DLL 访问 64 位 DLL

Question

我正在将CEF4Delfi库移植到 Borland C++Builder 5。我从移植的 CEF4Delfi 源代码制作了一个 BPL 包，并从我的 C++Builder 5 代码中引用它。

我在 Windows 10 64 位上工作。

在移植时，我一直坚持导入 DLL 函数。

以下是部分导入：

const
  Kernel32DLL = 'kernel32.dll';
  SHLWAPIDLL  = 'shlwapi.dll';
  NTDLL       = 'ntdll.dll';
  User32DLL   = 'User32.dll';

function ProcessUnderWow64(hProcess: THandle; Wow64Process: PBOOL): BOOL; stdcall; external Kernel32DLL name 'IsWow64Process';
function PathIsRelativeAnsi(pszPath: LPCSTR): BOOL; stdcall; external SHLWAPIDLL name 'PathIsRelativeA';
function PathIsRelativeUnicode(pszPath: LPCWSTR): BOOL; stdcall; external SHLWAPIDLL name 'PathIsRelativeW';
function GetGlobalMemoryStatusEx(lpBuffer: LPMEMORYSTATUSEX): BOOL; stdcall; external Kernel32DLL name 'GlobalMemoryStatusEx';
function PathCanonicalizeAnsi(pszBuf: LPSTR; pszPath: LPCSTR): BOOL; stdcall; external SHLWAPIDLL name 'PathCanonicalizeA';
function PathCanonicalizeUnicode(pszBuf: LPWSTR; pszPath: LPCWSTR): BOOL; stdcall; external SHLWAPIDLL name 'PathCanonicalizeW';
function PathIsUNCAnsi(pszPath: LPCSTR): BOOL; stdcall; external SHLWAPIDLL name 'PathIsUNCA';
function PathIsUNCUnicode(pszPath: LPCWSTR): BOOL; stdcall; external SHLWAPIDLL name 'PathIsUNCW';
function PathIsURLAnsi(pszPath: LPCSTR): BOOL; stdcall; external SHLWAPIDLL name 'PathIsURLA';
function PathIsURLUnicode(pszPath: LPCWSTR): BOOL; stdcall; external SHLWAPIDLL name 'PathIsURLW';
function ShutdownBlockReasonCreate(hWnd: HWND; Reason: LPCWSTR): Bool; stdcall; external User32DLL;
function ShutdownBlockReasonDestroy(hWnd: HWND): Bool; stdcall; external User32DLL;

由于链接，我收到错误，例如：

Error: Unresolved external 'PathIsRelativeA' referenced from C:\REPOS\CEF4DELPHI\SOURCE\UCEFMISCFUNCTIONS.OBJ
Error: Unresolved external 'AlphaBlend' referenced from C:\REPOS\CEF4DELPHI\SOURCE\UCEFBUFFERPANEL.OBJ
Error: Unresolved external 'IsWow64Process' referenced from C:\REPOS\CEF4DELPHI\SOURCE\UCEFMISCFUNCTIONS.OBJ

如您所见，c:\windows\system32;包含在路径中。

所以，我假设从 32 位应用程序导入 64 位 DLL 存在问题，整个互联网都说这是真的。

我开始在一个单独的 C++ 模块中使用来自的代码重新实现这些函数Wine，但它确实是非常多的代码。突然间，我看到我们用 C++Builder 5 构建的另一个 32 位 DLL 实际上确实引用了 64 位 DLL！

那么，System32从使用 C++Builder 5 构建的库中调用 64 位 DLL 函数的技巧是什么？

更新：

以下是这些函数实际上是从父 DLL 导入的证据：

好的，这是makefile：

对于@PaulMcKenzie：我有一个 64 位操作系统，我需要使用 Borland C++Builder 5 构建一个 32 位应用程序才能在 64 位操作系统上运行。Unresolved external当我从文件中引用驻留在 Windows DLL 中的 Windows 函数时，我遇到的问题是错误问题.pas。

好的，谢谢大家，让我了解了DLL导入的过程。

正如所说 - 的导入需要IInspectable与. 这里有更多解释。还有谷歌 - “将共享库链接到可执行文件”。是还是不重要，原则是一样的。Remy LebeauDLLLIB.so.dll

在我给出解决方案之前，还有一点很重要。

如前所述Remy Lebeau：几个功能

BCB5 发布时还不存在（或不久前引入）

解决方案

第一的

修复makefile

LIBRARIES = Rxctl5.lib shlwapi.lib kernel32.lib user32.lib
LIBPATH = ...;..\libs;

在部分中添加所有必要.lib的文件LIBRARIES。
将新文件夹添加到LIBPATH部分中的路径。

第二

尽管在您的安装中存在具有.lib功能的文件夹：BCB

您需要重新创建.lib文件。我已经Borland C++ builder安装在T:\虚拟驱动器上：

> cd ..\libs
> T:\Bin\implib.exe kernel32.lib c:\Windows\SysWOW64\kernel32.dll

我将库放在..\libs相对于makefile.

第三

的编译器中存在错误Borland。它无法编译从类方法对外部函数的调用，因此您需要添加代理：

unit uCEFMiscFunctions;

interface

const
  Kernel32DLL = 'kernel32.dll';

{$IFDEF MSWINDOWS}
function GetGlobalMemoryStatusEx_(lpBuffer: LPMEMORYSTATUSEX): BOOL;
function GetGlobalMemoryStatusEx(lpBuffer: LPMEMORYSTATUSEX): BOOL; stdcall; external Kernel32DLL name 'GlobalMemoryStatusEx';
{$ENDIF}

implementation

{$IFDEF MSWINDOWS}
function GetGlobalMemoryStatusEx_(lpBuffer: LPMEMORYSTATUSEX): BOOL;
begin
  Result := GetGlobalMemoryStatusEx(lpBuffer);
end;
{$ENDIF}

unit uCEFApplicationCore;
...
function TCefApplicationCore.GetTotalSystemMemory : UInt64;
{$IFDEF MSWINDOWS}
var
  TempMemStatus : TMyMemoryStatusEx;
{$ENDIF}
begin
  Result := 0;
  {$IFDEF MSWINDOWS}
  ZeroMemory(@TempMemStatus, SizeOf(TMyMemoryStatusEx));
  TempMemStatus.dwLength := SizeOf(TMyMemoryStatusEx);
  if GetGlobalMemoryStatusEx_(@TempMemStatus) then
  if True then
    Result := TempMemStatus.ullTotalPhys;
  {$ENDIF}
end;
