linker - 基于 ATL 的链接器错误

Question

我最近遇到了 atls.lib 的链接问题。我更新了链接器的附加依赖项行:

comctl32.lib
C:\WinDDK\7600.16385.1\lib\ATL\i386\atls.lib
C:\WinDDK\7600.16385.1\lib\ATL\i386\atl.lib
C:\WinDDK\7600.16385.1\lib\ATL\i386\atlsd.lib

但是，现在，我开始收到这些错误。

什么会导致这些问题？

非常感谢。

我也必须调试这个问题。似乎 DLL bulid 不起作用，因为 atl.lib 中缺少许多函数。
我将“使用 ATL”切换为“静态链接到 ATL”。之后我只剩下 3 个缺少的符号，我发现这些符号是在 atlthunk.lib 中定义的。 .这个从未在 atlbase.h 中引用过。这就是我添加的原因

#pragma comment(lib, "atlthunk.lib")

至 atlbase.h就在 atls.lib/atlsd.lib 的调试是/否部分之前

之后构建成功。
