您如何找到哪个.lib文件与哪个函数一起使用？

Question

In the linker settings you should tell the compiler which .lib files to include. One simple thing that I haven't figured out is how to know which function is in which .lib file when using 3rd party software?

Example: I was recently using Qt which has a huge number of .lib files. After trying those with most obvious names, I had to go through them all by trial and error until I found the correct one. I thought this information would be in the documentation of Qt but failed to find it. I am still a beginner teaching myself so sometimes easy things like this pass me by.

Answer 1

There are two basic approaches.

The first option is to read the documentation for the third party library (Microsoft is very good at this - they include the library and header you need in each function. It seems Qt is not so good.)

The second option is to list the names in each library with DUMPBIN as described here .

As noted in the comments, a variant of the second option is to grep the .lib files for a the plain text of the function names. That will tell you which .lib files either define the function, or call it. If there is only one, you are done; if more than one, you will have to run DUMPBIN on all the returned files to see which defines it.
