问题
TL;DR Is there a flag or something that will tell msvc to print out which library/object file requires a given library?
say I get an error message like:
LNK1104 fail to open file: boost_thread-vc120-mt-gd-1_56.lib
I expect this because I haven't told msvc where to find that. But, let's say I want to know why do I need that?.
In other words, let's say I'm linking against foo.lib bar.lib and I've got a bunch of code in my project. Will msvc show me whether it's foo.lib, bar.lib, or my own code that needs it?
回答1:
adding /VERBOSE:REF shows which object files reference which symbols in which libraries, all in a nice indented fashion. This is what I was looking for.
回答2:
In Visual C++ additional libraries can be specified with #pragma comment(lib, "libname.lib") instruction in source code. It may be placed in library headers and is applied when header is included in application sources.
