Answer 1

have a look at the project settings , at Configuration Properties -> C/C++ -> Code Generation -> Runtime Library.

the setting , whether it MD , MTD or whatever, must be compatible between your library and ACE's library.

you should not manually ignore any library, there should be no need for that.
