验证库中使用的CRT（.lib） [英] Verifying CRT used in library (.lib)

问题描述

如何检查Windows中的静态库（.lib）链接到什么运行时库？

How do I check what runtime library a static library (.lib) in Windows has linked to?

我用/ MDd编译我的项目，我链接的库正在使用/ MTd多线程调试

I'm compiling my project with /MDd and I presume a library I'm linking to is using /MTd Multi-threaded Debug

Error   7   error LNK2005: "public: __thiscall std::_Lockit::~_Lockit(void)" (??1_Lockit@std@@QAE@XZ) already defined in libcpmtd.lib(xlock.obj)    C:\...\msvcprtd.lib(MSVCP100D.dll)

LIBCPMTD.LIB =多线程，静态链接

LIBCPMTD.LIB = Multithreaded, static link

我知道有一个选项 / NODEFAULTLIB：libcpmtd.lib这是我试过和成功，但我宁愿避免。

I know there's an option /NODEFAULTLIB:"libcpmtd.lib" which I've tried and succeeded with, but I'd rather avoid that.

推荐答案

我可以解决这个问题。

我使用/ MDd重新编译lib，它链接得很好。

It's cleary linking to MT. I recompiled the lib using /MDd and it linked fine.
