I'm afraid that we don't support ROBOTC in Wine. It will run very nicely inside a VMware Virtual Machine running Windows, though. You may want to take a look at that instead.

Thanks for your answer :)
It really may not work with Wine ?
Does someone has already tried it ?

Hi Koyochi.

I have also been experimenting with RobotC under Wine as RobotC is the only C based language allowed in RoboCup Junior but our school laptops are Mac which RobotC doesn't support.

I had considered using a VM but this doesn't seem very practical. It would require every student to purchase a Windows license to run RobotC on their MacBooks and saying "Yeah RobotC is great. It's a bit harder to use, but much more powerful. Oh but you will need to install a VM, learn how it works, install a full copy of Windows, get your parents to pay for a license Windows License, as well as RobotC, explain to them why you need this etc..." - I can't see it happening.

It might be a good idea to put some pressure on the Wine Developers to try to find a solution.

Cheers

If it helps anyone, I have solved the problem.

You need to copy the following Windows files in to your .wine/windows/system32 directory:

bthprops.cpl
devmgr.dll

I haven't fully tested it as I don't have my EV3 brick here at the moment, but I can now get in to the Communications Link Setup menu without any errors.

Cheers,
Stuart

Got same problem on Windows Server R2 Standard running in VirtualBox hosted on MacOS.
Code:
'EV3 Device Drivers' (Casper.dll) have not been installed.
Communications to EV3 is not possible.

How to resolve this problem?

I managed to solve the Casper.dll problem with what I've mentioned above, which let me access the comms menu without errors however I was still not able to connect.

Running wine robotc.exe from the terminal gave me some very useful information on what files robotc was looking for... Not sure how you would do that in a VM.

Communications would have been possible if the EV3 used standard windows com ports, but from what I can see, it seems to come up as a HID which is rather annoying.

I find it a little disappointing that the RobotC developers aren't a more helpful in providing a work-around for us. I don't set the IT policies here and our organisation has chosen Apple which means without a work-around, we simply can't use RobotC and we're stuck with Labview. :(

I've used ROBOTC on Windows 7 and 8 in a VMware Workstation VM. Is there a specific reason you're using Windows Server 2008 R2? Are you trying to create some kind of Terminal Server configuration with remote clients to allows multiple people to use ROBOTC simultaneously through an RDP client?

The fact that the EV3 uses HID is, unfortunately, not something that can be changed, that's how the system was designed by LEGO.

Are you using VirtualBox or VMware Fusion? I have had very mixed results with VirtualBox and USB devices.

The reason is that I have such license got by Dreamspark program.

Oh... I just realised that tty.EV3-Serialport is the bluetooth link. That doesn't work on Yosemite either. :(

Does it not also allow you to have Windows 7 and 8 licenses as well?

Consider using a trial version of VMware Fusion to see if you have issues with that as well. Like I said, USB and VirtualBox is flaky, it's the one reason I switched to VMware products.
