Im using an external libary for my project, how can I compile when two libs are using the same names? --------------------Configuration: NewPlayerStatic - Win32 Release-------------------- Linking...

you appear to be getting a runtime library clash, make sure everything is being compiled with the same runtime library

Yeah, it looks like you're linking with both the static and DLL runtimes at the same time! If you go to Project Settings -> C/C++ -> Code Generation -> Runtime Library you can set which version you want to link against, and MSVC should know how to build the proper command line. At least it knows how for me [smile] If you click on the Help button it will also give you some detailed information about the libraries you need to include and exclude for each version.

Turn off multithreading if you don't need it, that's what's causing the conflict--the linker is linking against both the non-multithreaded and multithreaded versions of the C runtime libraries.
