This warning: LINK : warning LNK4098: defaultlib 'MSVCRT' conflicts with use of other libs; use /NODEFAULTLIB:library is a fairly common warning in Visual Studio. I'd like to understand the exact reason for it and the right way (if at all) to handle it. This comes up in a debug build, compiled with /MDd . The project is linked to things like windows Version.dll and pdh.dll which themselves link with MSVCRT.dll . Obviously, I don't have the debug versions of these and can't compile them. So I added /NODEFAULTLIB:MSVCRT to the linker command line and it actually did remove the warning. But what

It\'s not yet done, as I am in the process of making the console used to connect to the server. I am trying make a login window where a user is prompted to enter their Username and Password, although when the password is entered I am looking for

问题 Should I redistribute msvcrt.dll with my application and use the private dll if some of the application\'s libs dynamically depend on msvcrt.dll? I.e. are any incompatibility issues possible with the system\'s msvcrt.dll (dll hell)? Application is targeted for Windows Server systems. 回答1: msvcrt - is a dynamic library for the Microsoft Visual C++ runtime. There are two options for using the C runtime in Windows: link with static runtime libs. Use either the /MT or the /MTd option to cl.exe.

Should I compile with /MD or /MT?

问题 In Visual Studio, there\'s the compile flags /MD and /MT which let you choose which kind of C runtime library you want. I understand the difference in implementation, but I\'m still not sure which one to use. What are the pros/cons? One advantage to /MD that I\'ve heard, is that this allows someone to update the runtime, (like maybe patch a security problem) and my app will benefit from this update. Although to me, this almost seems like a non-feature: I don\'t want people changing my runtime
