c++ - 如何在 VS 2008 中编译 64 位 native C++ DLL？

Question

我正在尝试将 native ATL C++ 进程内 COM 服务器移植到 Visual Studio 2008 中的 64 位。我打开了配置管理器，添加了“x64”平台。现在我有 6 个配置 - 3 个用于 Win32，编译和链接正常，3 个用于 x64，编译正常，但使链接器发出以下错误:

\Debug64\Objects\common.obj : fatal error LNK1112: module machine type 'X86' conflicts with target machine type 'x64'

我要改变什么才能消除这种情况？

UPD:已解决，问题来源非常愚蠢，请参阅下面的回答。

Answer 1

您是否在安装 visual studio 期间安装了“x64 compiler and tools”组件？

还要检查这些设置:( copied from msdn )

• /MACHINE (Specify Target Platform) is set to /MACHINE:IA64 or /MACHINE:X64.

• Register Output is turned OFF. For more information, see Linker Property Pages.

• Target Environment is set to /env x64 or /env ia64. For more information, see MIDL Property Pages: General.

• Validate Parameters is cleared and reset to the default value. For more information, see MIDL Property Pages: Advanced.

• If Debug Information Format was set to /ZI in the Win32 project configuration, then it is set to /Zi in the 64-bit project configuration. For more information, see /Z7, /Zi, /ZI (Debug Information Format).

• Values of WIN32 are replaced by WIN64 for /D (Preprocessor Definitions).
