我最近遇到了与 atls.lib 的链接问题。我更新了链接器的附加依赖项：

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？

非常感谢你。

在项目设置中，将“使用 ATL”从“动态链接到 ATL”更改为“静态链接到 ATL”。

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“到 ATL 的静态链接”。之后我只剩下 3 个缺失的符号，我发现这些是在atlthunk.lib. atlbase.h 中从未引用过这个。这就是我添加的原因

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

在atlbase.h调试是/否部分之前atls.lib/atlsd.lib

之后构建成功。

atls.lib 是 ATL 的静态库。atlsd.lib 是该库的调试版本。您在同一个版本上链接到两者，因此您获得了多个定义。此外，如果您想使用 ATL 的动态库，您应该链接到 atl.lib。因此，要么使用 atl.lib，要么在发布版本中使用 atls.lib，在调试版本中使用 atlsd.lib。但不要将它们混合在一起。
