如何判断一个库是用/mt 还是/md 编译的?

How to tell if a lib was compiled with /mt or /md?(如何判断一个库是用/mt 还是/md 编译的?)

问题描述

给定一个编译的lib，有没有办法通过查看它来判断它是用/md还是/mt编译的(也许使用 dumpbin 工具)?

Given a compiled lib, is there a way to tell if it was compiled with /md or /mt just by looking at it (maybe with dumpbin tool)?

dumpbin/directives foo.lib 是针对 lib 未使用 /GL 开关编译的情况的解决方案.是否可以选择检查以这种方式优化的 lib 文件?

dumpbin /directives foo.lib is a solution for the case where the lib was not compiled with /GL switch. Is there an option to inspect a lib file that was optimized in such a way?

推荐答案

是的，您可以使用 dumpbin 的 /DIRECTIVES 选项来查找 .lib 中的对象想要链接到哪些运行时库:

Yes, you could use dumpbin's /DIRECTIVES option to find which runtime libraries the objects in the .lib want to link with:

dumpbin /directives foo.lib

在此处查找指定的运行时库的实例.例如，您可能会看到:

Look for instances of the runtime libraries specified here. For example, you might see:

/DEFAULTLIB:MSVCRTD(使用/MDd 编译的模块)

/DEFAULTLIB:MSVCRTD (module compiled with /MDd)

或

/DEFAULTLIB:MSVCRT(使用/MD 编译的模块)

/DEFAULTLIB:MSVCRT (module compiled with /MD)

或

/DEFAULTLIB:LIBCMT(使用/MT 编译的模块)

/DEFAULTLIB:LIBCMT (module compiled with /MT)

可能会有很多 /DEFAULTLIB 指令，因此您可以使用以下术语进行搜索:

There will probably be many /DEFAULTLIB directives, so you can search using terms like:

dumpbin /DIRECTIVES foo.lib | find /i "msvcr"
