Fatal error liquidcrystal h no such file or directory - Исправление ошибок и поиск оптимальных решений проблем

I’m fairly new to Atom / PlatformIO and tried using it for development with Arduino as an alternative to Arduino IDE.

~The Specs~

base code used: Arduino ESP sample code "WifiBlueToothSwitch.ino"
Board: ESP-WROOM-32
Additional Components: 1602A (2x16) LCD

I’ve successfully run other sample code on the ESP module through PlatformIO prior to attempting to use the LCD screen, however when I did attempt to include the LiquidCrystal.h library, it gives me a build error:

srcmain.cpp:22:27: fatal error: LiquidCrystal.h: No such file or directory
compilation terminated.
*** [.pioenvsesp32devsrcmain.o] Error 1
[ERROR] Took 3.34 seconds

So of several of the sites I’ve searched about this issue so far, most point to the missing addition of the «wire.h» header file, however even after including it into the program, it still gives me this error.

My includes are as follows:

#include <Arduino.h>
#include <WiFi.h>
#include <Wire.h>
#include <LiquidCrystal.h>

So I’m not entirely sure why this problem is occurring.
How can I resolve this issue?

Edit 1:

I came across another site a moment ago that suggested attempting an update of PlatformIO via console, however this was to no avail. Everything was marked as «Up-to-date».

Edit 2:

I have compiled and run this code through the Arduino IDE and can confirm that it works, so the problem seems to be with the PlatformIO IDE…

Edit 3:

After following BMelis’s suggestion, I looked into the PlatformIO.ini file, and added the following line to it:

lib_extra_dirs = C:Program Files (x86)Arduinohardwareespressifesp32libraries

This fixed the initial error for the LiquidCrystal.h, However this also produced the following dependency error during build:

I tried adding the directory that it was mentioning by adding a second lib_extra_dirs command in the ini file:

lib_extra_dirs = C:Program Files (x86)Arduinohardwareespressifesp32toolssdkincludelwipapps

However this did nothing to resolve the issue. I am at a loss as to what to do now…

It’s 11 PM on a Wednesday. You’ve just spent three hours toiling on your next Arduino project, and FINALLY, you’re ready to give your sketch a whirl. You hit upload, palms sweaty with anticipation to see all your hard work come to fruition. It’s then you see the error:

No such file or directory.

Surely this is a chance aberration. “Nothing to worry about,” you mutter, sleep-starved and semi-delirious as you hit upload again. And once more, those maddening words, “no such file or directory,” stare back at you in hostile gaslighting mockery.

Have you been here?

If you’re trying to run an Arduino sketch but keep coming across the “no such file or directory” error, don’t worry. This is actually a pretty common problem, and there are two easy fixes that almost always work.

Keep on reading. We’ll show you what they are.

No such file error!

Error messages can be such a pain. They do, however, serve a useful purpose by telling us something about what went wrong. At first glance, the no such file or directory error is particularly maddening because it seems to break that useful purpose rule. Of course there’s a file or directory! You just made the thing, and it’s right there, tucked inside a directory.

But hold up, let’s take a closer look. If you look at the bottom portion of the Arduino IDE where the error message shows up, there’s this handy little button that says “copy error messages.”

Click on that now. You probably won’t fall off your chair to learn that by clicking that button, you just copied the error message from the little window at the bottom of The Serial Monitor’s UI to the clipboard of your computer.

This copy feature is ridiculously useful. You could, for example, paste the error message into Google and learn more about the error. Or you could take advantage of the active Arduino community by asking for help in a forum. For this situation, however, we can be a bit more basic. All we’re going to do is take a closer look at what the message is actually saying. To do that, just fire up your PC’s text editor and paste it into the blank screen.

Decoding the no such file error

Here it is, that pesky error in all its freshly pasted glory.

I’ll break it down for you line by line.

The first line is easy. It’s just describing the Arduino version in use, what operating system is running, and which board you have selected.
Line 2 begins to zero in on the problem.
- The first bit, “knob,” is referring to the name of the program. This is your sketch, basically.
- The second bit is what usually begins to confuse people, but it’s easy once you know. The “10” in this example is telling you the error occurred on line 10 of your sketch. The “19” is telling you the length of the line of code in spaces and characters. The first number is usually the more helpful of the two because you can use it to locate the error in your sketch.
Then we get to the smoking gun of the error. It says, “servo.h: No such file or directory”.

So this thing, “Servo.h.” That’s the thing we need to fix, and thanks to line 2, we know where to find it. Line 10. It’s always line 10.

Now that we know what’s going on a bit better, let’s get down to the business of implementing a fix.

The error of our ways

Let’s lay down some scrutiny on this accursed line 10.

It says “#include <servo.h>”

When we verify this code, this line is telling the Arduino IDE compiler, “Hey, for this program to work, you need to go get this file called servo.h”.

Let’s say you had a label-making machine, and you wanted to use it to print some cool motivational labels, like “Success!” and “Keep Trying!” and “Look, Nachos!” To make that happen, you’ll first have to load in a roll of labels. No roll of labels? Well, then the label maker isn’t gonna work.

The sketch you’re trying to upload is like the label maker. The file (in our example, the file named “servo.h”) is the roll of labels.

So the error message actually is saying something useful. It’s saying, “Hey programmer, you said I needed this other file. Well, I looked for it and it’s not there. What gives?”

Now we know the error message isn’t complete gibberish, let’s look at the two most common scenarios that cause it.

Scenario 1 – Fat fingers

This sketch is one that you’ve written. You’re actually the one who wrote the “#include” line. The first thing you should check is your spelling and capitalization. Maybe you spelled the name of the library incorrectly? Or (as with the example below) perhaps you capitalized the wrong letters.

So “servo.h” should actually have a capital “S.” In full and with correct capitalization, it should read, “Servo.h.” You’ll notice above that the word servo changes color when it’s correctly capitalized. That color change signifies that the library name “Servo” is recognized as a “keyword” in the Arduino IDE.

Keep in mind that might not be the case for all the libraries you’re using. In other words, the color change won’t always indicate you’re using the right spelling or capitalization, but it’s often a helpful visual reminder.

Oh, and it’s probably good to mention that everyone in the history of Arduino programming has misspelled or incorrectly capitalized a word at some point. It’s amazing how long you can stare at a line of code and miss something like that.

So don’t sweat it.

Scenario 2 – Missing files

This brings us to the next common scenario for the “no such file or directory” error.

So often, working with Arduinos involves taking code that someone else has developed and shared online and then tailoring it to your project. That’s part of what makes it so easy to get stuff done with Arduino. One problem that frequently happens when we do that, however, is we accidentally introduce code without a matching file.

An easy way to check to see if you have the file a sketch is looking for is to navigate to Sketch > Include Library from within the Arduino IDE. Then look for the name of that library.

Whatever library the #include statement was calling for, you want to look through this big long list for a library with the exact same name. If you don’t see the file name there, this means the library isn’t installed. You’ll have to add that library before the sketch will compile without errors.

So, how do you add that library?

The easiest way is to go to Sketch > Include Library > Manage Libraries. The Arduino IDE will open up a dialogue box from which you can search for the library you need.

Make sure you type the exact word that matches the #include line. Once you find the missing library, go ahead and click Install. The Arduino IDE will let you know that it’s installing the library you requested and updating the software accordingly.

Next, just double-check that the library has been successfully installed by going to Sketch > Include Library. You should see your new library in the dropdown list.

Good news! If the library is there, you should now be able to compile your sketch error-free.

Other library locations

OK, there’s one little fly in the ointment. How do these dang ointment flies always manage to complicate things so?

Here’s the thing. Not all libraries live in this convenient pop-up window inside the Arduino IDE. The Arduino community is bubbling with clever ideas, but cleverness (unlike processed cheese) doesn’t always come in conveniently standardized, individually wrapped slices. There are tons of different ways to find Arduino libraries on the web.

If you’re downloading or copying a program from the internet, just go to the page where you got that program and take a close look at the library the author is referencing. They may, for example, have a link to GitHub, which is a place where people keep a lot of code libraries.

Wherever you find it, usually the library will be included in a .zip file package. Once you’ve downloaded the .zip file, fire up the Arduino IDE and go to Sketch > Include Library > Add .ZIP library. Then navigate to the location you downloaded the file and select it. Assuming no additional ointment flies invade your workflow, the Arduino IDE will pop up the message “Library added to your libraries” just above the dark area where the original “no such file or directory” error appeared.

Now it’s business as usual! Just go to Sketch > Include Library, and the new library will appear in the drop-down list.

As the dyslexic Frenchman once said to the oversized violinist: “Viola!”

You now know not one but two ways to add a new library. What a time to be alive!

Review

A quick recap, then.

We’ve looked at the two main scenarios that cause the “no such file or directory” error to appear after you compile your sketch:

The fat fingers phenomenon: Check your spelling and capitalization! If you wrote the sketch, there’s a mighty good chance you introduced a tiny error. And don’t beat yourself up over it! Literally every coder has done this.
The missing files mixup: Failing that, if you copied code from someone else check that you have the correct libraries installed. Don’t see your library? Install it using the method described above, and you should be good to go.

There may be no such thing as a free lunch, a coincidence, or a luck dragon. But rest assured. Your files and directories? They’re alive and well.

I’m trying to start with the SainSmart 4×20 serial LCD, and copied the library to the Arduino library:

So LiquidCrystal_I2C.h is included. But when I try to compile an example sketch it says

Arduino: 1.7.0 (Windows 7), Board: «Arduino Uno»

HelloWorld_i2c.pde:2:31: fatal error: LiquidCrystal_I2C.h: No such file or directory

compilation terminated.

Error compiling.

Any ideas how to fix this?

I copied the SainSmart library to the IDE’s library folder, not noticing that there was already a folder named «LiquidCrystal». Apparently the files added to the existing folder are being ignored.

Renaming the SainSmart library before adding it solves the problem.

There is not enough info to give a specific answer so I will give some troubleshooting tips:

First make sure at the top of your code you have: #include <LiquidCrystal_I2C.h> — with angle brackets
You may also need the Wire header file: #include <Wire.h> — with angle brackets
Make sure you Include Serial
Make sure there are no extra folders in the library for example there should be a folder called liquidcrystal inside the liquidcrystal folder
If all fails copy the code from the header file make a new file in the IDE paste it in there and call it LiquidCrystal_I2C.h

Hope one of those solves your problem.

exit status 1

Ошибка компиляции для платы Arduino Nano.

Давайте удалим все тут: C:UsersихихиихDocumentsArduinolibrariesLiquidCrystal

meganom, установить нужно только одну. Это не тот случай, когда чем больше, тем лучше.

И так, я скачал скетч, открываю его. Вижу что в начале есть подключение двух библиотек

#include <Wire.h>

#include <LiquidCrystal_I2C.h>

Wire.h почему-то написана красным шрифтом а LiquidCrystal_I2C.h черным , что это значит я не понял, но скорей всего это значит что одна библиотека подключена а вторая нет . Дальше мне последовательность действий не понятна. Как правильно подключить библиотеку LiquidCrystal_I2C.h и Wire.h ? Я так понимаю, что они должны находится в папке library среды ардуино , и при начале компиляции проекта среда лезет в эту папку и подтягивает эти библиотеки если их нет то выдаёт ошибку .Мне не понятно где брать недостающую библиотеку и как правильно ее подключить к проекту .По идеи недостающая библиотека есть в папке с скетчем который я скачал . а проектах ардуино есть только два типа файлов , сам скетч и .h файл ? Сколько типов файлов нужно подключать к проекту ?

meganom, дайте результат компиляции скетча Blink

Если коротко, то библиотека: h — заголовочный файл (обычно указывают в include), cpp — реализация.

По include и другие конструкции языка таки следует почитать.

Это я все знаю . Объясните мне, куда положить или как подключить эти библиотеки если они у меня есть
