C++ Compilation: /MD vs /MT - Which one to choose?

When compiling C++ code in Visual Studio, developers are often faced with the decision between using the /MD or /MT flag. These flags determine the type of runtime library that will be linked to the final executable.

The /MD flag links the executable with the dynamic version of the runtime library, while the /MT flag links with the static version. The main difference between the two is that the dynamic version is shared among all processes using the same runtime library, while the static version is included within the executable itself.

So, which one should you choose? The answer depends on your specific needs. If your application needs to be as small as possible and you don't mind the extra overhead of loading the runtime library at runtime, then /MT may be the better option. On the other hand, if you want to reduce the risk of conflicts with other processes using the same runtime library and don't mind the slightly larger executable size, then /MD is the way to go.

It's worth noting that choosing the wrong flag can lead to runtime errors and crashes, so it's important to carefully consider your options and test your code thoroughly with each option.

In summary, when choosing between /MD and /MT in C++ compilation, it's important to weigh the trade-offs between a smaller executable size and reduced risk of conflicts with other processes. Ultimately, the decision should be based on the specific needs of your application.
