Why does the compilation of opencv download lots of things?
I just downloaded the opencv 3.3.1 from the official website and compiled it successfully.
I've found that it downloaded many data files and put them into a hidden directory: .cache
, whose size is 113 MB.
I think this directory is used to do some tests while compiling.
If I'm right, is it possible to pass over this download and these tests so that I can compile the whole opencv without Internet?
BTW, I have to choose 3.3.1 because my project depends on this version and I have no right to use another.
3.3.1 is outdated, why did you choose that ?
@break Because my project depends on this version.
