I am trying to get back into this Compiler and I am beginning to remember why I abandoned it.
I started a little project with an LCD and RTC data logger shield and nothing will compile, NOT EVEN the example programs!
Here's an attempt to compile C:\Program Files (x86)\National Instruments\LabVIEW 2014\vi.lib\Aledyne-TSXperts\Arduino Compatible Compiler for LabVIEW\Code Generator\Arduino APIs\Timing\Read RTC Time and Format.vi
1.0.0.21, Arduino/Genuino Uno

You are trying to build a sub-vi, not an example. The example you want is probably DS1307 Real Time Clock.vi in the examples folder. This calls the Read RTC Time and Format.vi subvi above. The reason there is an error is because the Read RTC Time and Format.vi subvi does not initialize and open the I2C peripheral. That is handled at the beginning of the example and is required for it to compile properly.

Hmm okay in that case I may have been trying to compile the sub-vi. I was just trying to figure out why nothing will compile anymore when I know this compiler works and I have used this before being one of the pre-release buyers.
Now even trying to compile "Blink LED.vi" gets this error
Why is compiling "Blink LED" also trying to compile "Read_RTC_Time_and_Format" ?

I took a look at your submitted error logs and files and I was able to compile the submitted code for the example above ok on my end. It looks as if something happened with you local Arduino Wire library but not sure why it would even try compiling anything from Wire with this example. I did a search on the Arduino forums and here are a few links that may help. Did you try restarting everything down and restarting? It almost looks like a cached code issue from your other VIs that use Wire. You could also try uninstalling and reinstalling the Arduino IDE to see if that resolves it.

https://forum.arduino.cc/index.....c=513171.0
Also, in one of your submitted projects there is the use of a '?' in the case selectors, which conflicts with the ternary operator in C and should not be used. If you remove that from the case selectors, then this one compiles fine.
