How to expand the .lib with its source in c++?

Now my problem requires a .lib and I've grabbed all the source for that library,how can I replace the .lib开发者_运维技巧 dependance with its source code so that I can trace directly in source level instead of disassembly?

If you compile the source files for the .lib file with debugging information included, then you can continue to link the .lib file into your executable and the debugger will know how to find the source files.

You may be using a .lib file at the moment that's compiled without debugging information, so the debugger will not support source-level debugging of that code.
