那些遇到过的问题

从 32 位 DLL 访问 64 位 DLL

Olg*_*ova 5 c++ dll winapi c++builder c++builder-5

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

我使用的是 Windows 10 64 位。

在移植时，我陷入了导入 DLL 函数的困境。

以下是部分进口：

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';

如您所见，c:\windows\system32;包含在路径中。

因此，我认为从 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。

我开始使用来自 的代码在单独的 C++ 模块中重新实现这些函数Wine，但代码确实非常多。突然我发现我们用 C++Builder 5 构建的另一个 32 位 DLL 实际上引用了 64 位 DLL！

图像

System32那么，从使用 C++Builder 5 构建的库中调用 64 位 DLL 中的函数有什么技巧呢？

更新：

以下证据表明这些函数实际上是从父 DLL 导入的：

Olg*_*ova 2

好的，谢谢大家，让我了解了DLL导入的过程。

正如IInspectable并Remy Lebeau所说 - 的导入DLL需要与LIB. 这里有更多解释。还谷歌 - “将共享库链接到可执行文件”。是还是.so不是并不重要.dll，原理都是一样的。

在我给出解决方案之前还有一个重要的观点。

如前所述Remy Lebeau：几个功能

BCB5 发布时尚不存在（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;
Run Code Online (Sandbox Code Playgroud)
  1. 在部分中添加所有必需的.lib文件LIBRARIES。
  2. 将新文件夹添加到LIBPATH部分的路径中。

第二

尽管.lib您的安装中存在具有功能的文件夹BCB：

在此输入图像描述

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
Run Code Online (Sandbox Code Playgroud)

我将库放在..\libs相对于makefile.

第三

的编译器有一个错误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}
