So I got a laptop (my sister's old macbook) and I put arduino on it, etc.
I wanted to have access to all my sketches on my main computer. (iMac running snow leopard)
So I set up the arduino sketchbook folder on the imac as a shared folder. This appears as a new volume on the macbook, and I can navigate all my sketches folders in it.
I set arduino on the macbook to use this shared folder as the sketchbook folder, and all the files and folders appear in the arduino IDE. I can open and save files perfectly fine.
However, arduino on the macbook does not appear to recognize the libraries folder in the sketchbook folder; consequently, I cannot use the libraries that were on the iMac.
For now, I will install the libraries in the contents of arduino.app, I can live with having to reload them when I update Arduino.
But is there a solution to the shared folder libraries problem?
On the iMac, I selected "get info" from the right click menu on my sketchbook folder, then changed the permissions to read and write for an account that I log into on the laptop. Then, key step: I hit the icon with the gear and selected "apply to enclosed files" or whatever. I guess the libraries folder had not been marked as readable before.
Hope this helps anyone who is trying this same thing!
