Adding nonfree module

edit savecancel

• which opencv version is it ? os / compiler / cmake version ? we need all information we can get to help you
• which problems did you encounter, exactly ?

Is there any other way to do it not using cmake?

no, there isn't.

Opencv 3.0, my problem is that I do not understand the instruction of adding the module.

1. select the opencv source code folder and the folder where binaries will be built (the 2 upper forms of the interface) - Which folder is it?

2. press the configure button. you will see all the opencv build parameters in the central interface - there are not such parameters

• there is no more a nonfree module in opencv3 . sift and surf were moved to opencv_contrib repo
• please do anyone a favour, and get opencv3.1 (from github) also opencv_contrib , see build receipe there.
• the "build" folder is a temporary one, just choose any location you want
