[Interest] Whats the difference between compiling with /MD and /MT?

[Nuno Santos]

Thiago,

Thanks for your reply. 

You have just confirmed me what I have understood from my readings on the MSDN documentation. Question:

When the -static flag is passed to configure what configure does? Because from the compile output I can see the /MD flag even when compiled statically. 

I have manually edited the msvc-desktop.conf and changed from MD to MT. Will this make Qt completely independent of the runtime dynamic lib? What are the implications of doing this?

Thanks,

Regards,

Nuno
