Revision history [back]

there's a heap of changes between 2.4.6 (released in 2013(!!) and 3.2

it's no more a matter of replacing dlls, you'll probably have to rewrite some code. there's a rough http://docs.opencv.org/master/db/dfa/tutorial_transition_guide.html, but for details, we might need to know coarsely, what your code is doing (features2d ? ml ?)

just don't tell us, you have IplImages in your codebase....

only 64bit vs2015 libs are shipped nowadays, for 32bit(and any other compiler), you definitely have to build from src
