gem "minitest" and others ?

[jimc]

Im so far failing to build ruby-opencv.
I ended up adding 2 gems, both seemed to bring progress,
after several rounds of raking, bundling, gemming
(kinda new at ruby, so uncertain ...)

Hi,

Sorry for the late reply.

Ruby 2.2 includes minitest and test-unit gems.
What the error say when you build ruby-opencv without adding the 2 gems to Gemfile?

[jimc]

That was day 1 of ruby, of opencv, and their combo,
so its safe to say I didnt know what I was doing.
At some point I'll take that commit out, and see what happens.

In the meantime, I added another patch, to check opencv < 3.0,
which would have saved me a bit of groping.
I'll try repurposing this ticket with it.

ok, attachment was clipped. I'll try a pull request.

[jimc]

ok, I swapped the version<3.0 check (not yet PRd)
and the Gemfile addition the original patch seems to be needed here

Thanks.
