OpenCV in MFC App

[Don Guy]

Hey there,

I have a C++ app that uses OpenCV. Currently i am statically linking the OpenCV libs into my app. This is adding an extra overhead of 6+ MB.

Ideally i would like to remove some of the features that i am not using in OpenCV. The features am using are,

Capture frames from Webcam.
Face detection.
Image formats (JPEG, PNG).
Image rotation & resizing.
Is it possible to remove other features and trim down the libs?

My C++ app is developed in Visual Studio 2012.

Thanks in advance.

The linker should have features to remove unneeded stuff from the libraries you're importing (it may not do this by default to speed up the linking process).

Note however that you are stuck with how the library was made. If the library itself is causing interdependencies from one compiled module (usually a single C++ source file) to another and causing all the modules to be pulled into your exe, you're kinda stuck with that. It takes quite a bit of effort to make libraries that minimize these inter-lib-dependencies.
