I am getting a weird error message when I am using my Arduino Nano with a Mac on Monterey. Here is the message,
signal: killed
Compilation error: signal: killed
What could this mean? Is it my code, computer, board, connections, or a combination of them? I am programming a fingerprint sensor to open a solenoid valve, and the fingerprint sensor is not being recognized by the computer. Here is my code,

Did you ever manage to compile/upload a sketch to this board?
If you have other Arduinos, does it also happen?
Which exact Nano do you have? Genuine or clone? There are nowadays different Nanos (e.g. Nano, Nano Every, various Nano 33); I'm just trying to make sure that we're talking about the same one.
Which operating system?
Does the same error show when e.g. uploading blink?
If you have an older version of the IDE installed, does it also hapoen there?
Please post the full error output. Right click in the output window, click copy all and paste it here using code tags (the </> button)
Welcome to the forum.
I have split the posts you made on another topic and added them to the end of your topic. Please do not add your questions to the end of a different topic and please post your question once only.
I used an example code from Adafruit Fingerprint Sensor Library. It was called Fingerprint, and I edited it to work with the Solenoid, and to send a signal to the pin it was connected to. The code worked on a privies version of this build, with a Uno, and for a little while it has worked with the Nano. but it suddenly stopped. Should I use the the original Fingerprint code from the library? Thanks and have a great day.
It's strange as there does not seem to be much logic that could identify the issue.
One observation:
In the screenshot in post #9 you have the serial monitor open. Although this is not likely the cause, there was a bug in one of the release candidates that prevented uploads while the serial monitor was open; it should have been fixed in 2.0 but you could check if the issue is still present if you close the serial monitor.
What I forgot to ask
Does this happen when you try to upload or does it also happen when you only try to compile (verify).
With the exact same components? Please draw a schematic how everything is connected and drop it here in a post (not on google drive)?
And with exactly the same code? Or was it a newer version.
That might indicate a hardware issue with your Nano / components. What happens if you use the same components on the Nano that you use for the Uno?
Blink is one of the built-in examples that blinks the built-in LED. The question is asked to determine if this relates to your code (and libraries) or to the board / components.
So first try to upload blink() while everything is connected. If that fails, disconnect all external components and try to upload again. Please report back if (and where) it fails
If that's exactly (!) the same code it would indicate a problem in IDE 2.0. I'm not familiar with a Mac and have no idea where to look for the logs.
If we can't figure it out, I suggest that you (for this project) stick to IDE 1.8.19.
I was doing a little more testing, and it seems that updating my IDE to 2.0.1 worked. Thank you for all the help! I will come back if I have any more problems. Have a great day.
