No Such File or Directory Linux Upload
Are you trying to run an Arduino sketch, just keep coming across a "No such file or directory" error? This is a pretty mutual fault! Proceed watching to learn more about 2 piece of cake fixes for this fault.
No such file error!
Error messages can be such a hurting, only they're supposed to tell us something well-nigh the error nosotros made. Let's take a look at the one below. If you look at the lesser portion of the Arduino IDE where the error message shows upward, there's this handy little button that says "re-create error messages".
If you lot click on it, it copies the error message inside the fiddling window to the clipboard on the computer.
What y'all can do at present is paste it into Google, for example, and do a search which can assist you find out more nearly the error. Or you could paste information technology into a forum and say, "Hey, I've got this error message, delight help me."
For this situation, still, nosotros've copied information technology and we're going to paste it into a text editor so we can take a closer look at what the error message is actually saying.
Decoding the no such file error
The first judgement just says which Arduino version is in utilise, which operating system is running, and which board is selected.
The second sentence actually starts getting into the error a little scrap. The first affair information technology gives usa is the name of the programme. Then, in this case, the proper noun of the program was "Knob".
If you expect at the Arduino IDE, the the numbers on the left are called line numbers of the program and they're a reference to help united states discover where different lines of code are. The "ten" after "Knob" is the line number (in the Arduino IDE) that the error was detected on.
The "19" is a reference to how long that line of code is, so how many spaces or characters long is it.
Then information technology tells us the bodily mistake. It says "servo.h: No such file or directory". Why are we getting this error?
The error of our ways
Well, let's take a look at line 10 and see what it says. It says "#include <servo.h>"
When we verify this code, what this line does is tell the Arduino IDE compiler "Hey, for this program to piece of work, you demand to become get this file servo.h".
Let's say you had a label making motorcar and you were trying to run the label maker and impress some labels. To make information technology work, yous accept to put in a roll of labels. If you don't have that whorl of labels, then your label maker isn't gonna work. And then our programme'south like the label maker and the file (servo) is the curl of labels.
So the fault message is like "Hey, programmer, you said I needed this other file… but I looked for information technology and information technology's not there. What gives? Allow'south get to the bottom of this error message and go over two unlike scenarios.
Scenario 1 – fat fingers
This sketch is i that you've written. You're actually the one who wrote the "#include" line. The outset affair you lot should check is your spelling and capitalization. Maybe y'all spelled the name of the library incorrectly, or in this example, maybe you didn't capitalize the correct messages.
So "servo.h" should actually exist a capital letter "S", or written out, "Servo.h". Now in this instance, you'll notice that the give-and-take servo changes color when correctly capitalized, and that's because the library name "Servo" is recognized as a "key word" in the Arduino IDE. Keep in mind that might not be the case for all the libraries that you lot're using.
Therefore you can't utilise whether or not it color changed equally an absolute indicator, just it can be helpful. It is amazing how long you can stare at a line of code and miss something like a spelling or a capitalization error.
Scenario 2 – missing files
In this scenario you've either downloaded or copied and pasted some code from the internet and you're trying to run it for the kickoff fourth dimension. At present you start getting this mistake message. Allow's but assume that the original author of the programme spelled the name of the library correctly.
We'll go ahead and skip the troubleshooting associated with scenario 1. The next footstep would exist to verify that we actually have the file this program is calling for. Nosotros must also ensure the file is in the correct identify.
An easy mode to check to see if y'all accept that file is to be in the Arduino IDE and go to Sketch > Include Library, and so wait for the name of that library.
Whatever library the #include argument was calling for, you want to wait through this big long list for that library. If yous don't run into its verbal proper name in this listing, this ways you do not have that library installed appropriately (they're all in alphabetical order which helps). If you don't see it here, you'll have to add the library.
The easiest way to add a library is to get to Sketch > Include Library > Manage Libraries. Information technology will open up up a dialogue box and you can search for a library. In that location's so many libraries, you're definitely going to want to filter.
Brand sure you type the exact give-and-take that matches the #include line. Once you lot find the missing library click install. It will allow you lot know that it's installing the library and updating the list of libraries.
Next nosotros can double-cheque it has successfully installed. Go to Sketch > Include Library and the installed library should now announced on the drop downwardly list. Now, when it complies, you should no longer become the error.
Other library locations
Not all libraries are in this convenient popular-upwardly window when you get to manage libraries. There's tons of different ways to find Arduino libraries on the web. Often, if you're downloading or copying a program from the internet, but go to the page where you got that program and see what library they're referencing. Possibly they have a link to GitHub, for instance, which is a identify where people keep a lot of code libraries.
Unremarkably the library is included in a .zip file package. In one case you've downloaded the .zip file, you tin become to the Arduino IDE and go to Sketch > Include Library > Add together .ZIP library… Y'all just have to navigate to where the file was downloaded. Information technology will tell you "Library added to your libraries" merely above the nighttime area where the original error had appeared.
Now when we go to Sketch > Include Library, the new library volition appear in the drop-down listing. Viola! Y'all now know 2 ways to add a new library.
Review
So we've discussed two possible scenarios that could cause the "No such file or directory" mistake to announced after you compile your sketch.
First, if you wrote the sketch, just double-bank check your spelling and capitalization.
Second, if you have copied lawmaking from someone else, make sure you have the correct libraries installed.
We hope you have a great one and nosotros'll meet yous adjacent fourth dimension! Bye!
