Arduino 1.8.5 on macOS 10.13.1 and M2RET

[martinseener]

Hi, iam new to using the M2 to tinker around with my 2016 Skoda Octavia III and wanted to get M2RET running on my M2 with SavvyCAN at first. I've installed the newest Arduino Software and also installed the Board Configuration described on the Macchina page and was also able to upload and test the "LED Blink" Example, so the basic things seem to work.

Then i "git clone"ed all the libraries here (due_can, wire, mcp...) to ~/Documents/Arduino/libraries with their normal "git clone" names. Then i tried to Compile the also latest master clone of M2RET and got the following errors (i think the double libraries found thing is not a problem). Can you help me?

Thanks, Martin

This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences. `

Did this ever get resolved? It seems you had multiple versions of the same library installed to different places.

[martinseener]

Nope didn't work. Stopped trying. What do you think i should do in order to fix it?

[collin80]

I know you didn't think that the double found libraries thing was a big deal but it is. You ideally want it to only find one copy of the library. But, even so, I thought that I had fixed this after you had the trouble. If you update all your library versions it just might work. The trouble was that I updated libraries without changing their version numbers so when it found two copies they'd have the same version # even if one was newer. This should be corrected. Now if you have two copies the newer one should get used automatically.

Ok then i think we can close this issue. Also i remember that i got something to work (LED blinking stuff). It's been a while but i think i got it working anyways. Thanks for your help and for your great contribution btw!
