#Executable console app visual studio windows#

A solution may contain multiple projects. The base item of a project in Visual Studio is a solution. Inside the global section of this tutorial I'll show what the main differences are. There is a 2008 and previous versions and a 2010 way of doing it. In case of the global one how you do it depends on the Microsoft Visual Studio you use. The advantage of the global one is that you only need to do it once however, it may be undesirable to clump all your projects all the time with all this information.

To pass on all this information to the Visual Studio IDE you can either do it globally (so all your future projects will get this information) or locally (so only for you current project). The good part is that at runtime only the DLL is required.

This is why when you make some DLLs in Windows you will also end up with some lib extension libraries. Nevertheless, they aren't static libraries. This information is stored inside lib files. It seems that the linker needs to know that where in the DLL to search for the data structure or function at the runtime. If you use the DLL system you must again specify all this, however now for a different reason. During the build the linker will look into these libraries and add the definitions and implementation of all used functions and data structures to the executable file. If you use the lib system you must set the path where the library files are and specify in which one of them to look. Tell to the linker from where to get the functions or data structures of OpenCV, when they are needed. You do this by showing it the header files.

Tell to the compiler how the OpenCV library looks.

To build an application with OpenCV you need to do two things:

As a drawback your application will be larger one and as, it will take more time to load it during its startup. So there is no chance that the user deletes them, for some reason. When you use this the library will be built-in inside your exe file. You may build these by using our source files as described in the Installation in Windows tutorial. Of course you need to have the dll of the OpenCV on all systems where you want to run your application.ДЄnother approach is to use static libraries that have lib extensions. This means that if you have ten applications using the OpenCV library, no need to have around a version for each one of them. These have the advantage that all the content of the library is loaded only at runtime, on demand, and that countless programs may use the same library file. The OpenCV libraries, distributed by us, on the Microsoft Windows operating system are in a Dynamic Linked Libraries ( DLL).
