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

我在Windows 10 64位上工作。

在移植过程中，我被困在导入DLL函数上。

以下是进口的一部分：

代码语言：javascript
复制
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，我得到了错误，例如：

代码语言：javascript

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，路径中包含了c:\windows\system32;。

因此，我假设从32位应用程序中导入64位DLL存在问题，整个Internet都说这是真的。

我开始在一个单独的C++模块中重新实现这些函数，其中包含了来自Wine的代码，但它实际上是非常多的代码。突然间，我看到我们用C++Builder 5构建的另一个32位DLL实际上引用了64位DLL！

​

​

那么，从用System32 5构建的库中调用C++Builder 64位DLL函数的诀窍是什么呢？

更新

以下是函数实际上是从父DLL导入的证据：

好的，下面是makefile：

@PaulMcKenzie:我有一个64位的操作系统，我需要用Borland C++Builder 5构建一个32位的应用程序，以便在64位操作系统上运行。当我从我的Unresolved external文件中引用驻留在Windows中的.pas函数时，我遇到的问题是.pas错误。

好的，谢谢大家，让我了解DLL导入的过程。

正如IInspectable和Remy Lebeau所说，DLL的导入需要与LIB链接。这里是更多的解释。还有google --“将共享库链接到可执行文件”。无论是.so还是.dll都不重要，主体是相同的。

在我给出解决方案之前还有一个重要的问题。

正如Remy Lebeau所说:几个函数

BCB5发布时(或前不久)还不存在

解决方案

第一

修正makefile

代码语言：javascript
复制
LIBRARIES = Rxctl5.lib shlwapi.lib kernel32.lib user32.lib
LIBPATH = ...;..\libs;
  1. 在.lib部分中添加所有必要的LIBRARIES文件。
  2. 在LIBPATH部分的路径中添加一个新文件夹。

第二

尽管在您的.lib安装中存在带有BCB函数的文件夹：

​

​

您需要重新创建.lib文件。我在T:\虚拟驱动器上安装了T:\：

代码语言：javascript
复制
> cd ..\libs
> T:\Bin\implib.exe kernel32.lib c:\Windows\SysWOW64\kernel32.dll

我将库放在相对于..\libs的文件夹makefile中。

第三

Borland的编译器中有一个bug。它无法从类方法编译对外部函数的调用，因此需要添加代理：

代码语言：javascript
复制
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}
代码语言：javascript
复制
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;
