静态库依赖 [英] static library dependencies

问题描述

我在Windows平台上有一个静态库（.lib文件），我想知道构建lib时CRT库的依赖版本。我没有.lib文件的源代码，有什么想法吗？

I have a static library (.lib file) on Windows platform, I want to know the dependent version of CRT library when the lib is built. I have no source code of the .lib file, any ideas?

预先感谢，
George

thanks in advance, George

推荐答案

静态库没有这些依赖。构建该库后，它不会以任何方式与运行时链接，它所了解的只是实现标头文件中的函数声明，这些声明不提供任何版本信息。

Static libraries don't have those kinds of dependencies. When the library is built it is not linked with the run-time in any way, all it knows about are function declarations in the implementation header files, which don't provide any version information.

但是，假设库是MS格式的，则应该通过在文本编辑器中打开库（在执行备份之前进行备份）来查看库的构建标志。您正在寻找这样的一行：

However, assuming the library is in MS format, you should be able see what flags the library was built with by opening it in a text editor (make a backup before you do this). You are looking for a line like this:

cl.exe cmd -nologo -MTd -W3 -Gm -GX -ZI -DWIN32 -D_DEBUG  (more stuff)

-MTd标志告诉您该库是使用Multi-线程调试支持。

The -MTd flag tells you that the library was compiled with Multi-Threaded Debug support. .
