Have a static lib, is there a simple way to know it is for 32 bit or 64 bit?

Question

Is there any tool that can directly test if a library is made for 32 or 64 bit?

Answer 1

You can use dumpbin utility with /headers option

It returns whether the library was built for 32 or 64 bit architecture.

Check DUMPBIN Reference for details.

Example usage:

c:\>dumpbin libXYZ.lib /headers
