MRL on PI 2

Hello Guys, It has been a while. I hope everyone is doing good.

I have a PI 2 and I am trying to load MRL on it. I am getting a lot of errors so I send you a no-worky.

I only downloaded the JAR file.

trying to collect some

trying to collect some information here.

OpenCV is noworky in MRL 1.0.7 on all systems (due to the OpenCV-Upgrade), it would require some manual work.

We don't have a working OpenCV (for neither versions) for the Raspberry PI 2 in the repo, so when someone wants to use it, he would need to build it himself or get it from someone else, who already built it.

For MRL 1.0.107 OpenCV would be needed (to be build).

Aight .. let's nip this in

Aight .. let's nip this in the butt....

I got a raspi .. don't have a raspi 2 .. little concerned the ARM instruction set between the two might be different .. if that's the case .. then yes - we have to recompile ...

I looked for a resource to test .. and my faithful sprinkers replied... 

I got a login .. I'll see what I can do with the latest mrl version ...

Good tutorial

Hello a few days ago i wanted to load opencv and myrobotlab too on my raspberry pi 2.
I installed raspbian on a new sd card, set up the wlan, then followed this simple tutorial to install opencv:

Then i just had to download java with one command and installed myrobotlab (not the newest version).

And i had myrobotlab with the opencv system working in about 4h only. So thats probably a good way to recommend for a quick set up.
