Lost libraries during compile

glacierbill · November 8, 2026, 5:37am

I installed Arduino IDE on my D drive, for some reason the system has libraries on both C and D. Is some of my sketches (stored on D drive) I get some programs that compile just fine, but others using the same libraries tell me that the library is not found, any ideas?

Adruino Version
Version: 2.3.10
Date: 2026-06-09T16:48:46.639Z
CLI Version: 1.5.1

Please post the full paths to where the libraries are located on both drives

glacierbill · November 8, 2026, 6:34am

C:\Users\hoengager\AppData\Local\Arduino15
D:\Arduino\libraries

In the C drive the libraries are in a few different folders

Hi @glacierbill.

Please provide the output from a compilation of the program that is successful, and also the output from a compilation of the program using the same library that fails.

I'll provide instructions you can follow to do that:

Open the working sketch in Arduino IDE.
Select Sketch > Verify/Compile from the Arduino IDE menus.
Wait for the compilation to fail.
You will see a "Compilation error: ..." notification at the bottom right corner of the Arduino IDE window. Click the "COPY ERROR MESSAGES" button on that notification.
Open a reply here on this forum topic by clicking the "Reply" button.
Click the <CODE/> icon on the post composer toolbar.
This will add the forum's code block markup (```) to your reply to make sure the error messages are correctly formatted.

Code block icon on toolbar390×118 4.25 KB
Press the Ctrl+V keyboard shortcut.
This will paste the compilation output into the code block.
Move the cursor outside of the code block markup.

Now repeat the process for the non-working sketch:

Open the non-working sketch in Arduino IDE.
Select Sketch > Verify/Compile from the Arduino IDE menus.
Wait for the compilation to fail.
You will see a "Compilation error: ..." notification at the bottom right corner of the Arduino IDE window. Click the "COPY ERROR MESSAGES" button on that notification.
Click the <CODE/> icon on the post composer toolbar.
Press the Ctrl+V keyboard shortcut.
Click the "Reply" button to publish the post.

Unfortunately I do not remember what I was doing when last I got the error, but for now all the sketches seam to be working, I will post the error as soon as it shows up again.
The error comes and goes

ptillisch · November 8, 2026, 8:32am

I'm glad everything is working for you at the moment. I'll keep my fingers crossed that the problem has resolved on its own. We will be here to help if you do encounter it again.

It is really great having this resource. Many thank to all.

glacierbill · November 8, 2026, 10:00am

Also I notice when I float my mouse over each <Wires.h> it shows a different location for the file

Update, once I changed to use the same Arduino the addresses are the same, but still fails on the one sketch

Select File > Save from the Arduino IDE menus, then try compiling the sketch again. Does the error still occur when you do that?

UKHeliBob · November 8, 2026, 10:03am

Have you got the same Arduino board selected when you try to compile your working/not working sketches and which board is it ?

glacierbill · November 8, 2026, 10:09am

I originally did not, but I switched to the same board and still get the error

UKHeliBob · November 8, 2026, 10:13am

Please clarify. Are you saying that if you have the same board selected when compiling either sketch then one gives the error and one doesn't ?

Please turn on verbose output for compiling in the IDE, compile each sketch with the same board elected and post the full output from each compilation, including the full error message, using code tags when you post the output

Exactly which board have you got selected in the IDE ?

Which version of the IDE are you using ?

glacierbill · November 8, 2026, 10:25am

Yes, both are using the same Arduino R4 Wifi on com 5

I am not sure what you meant with using code tags but I copied the code error message and the compile data.

@glacierbill it seems you did not read post #10. Please perform the procedure I described there and then tell us the result:

glacierbill · November 8, 2026, 10:32am

I did not see that, I saved it and it did work, I will try that next time I get the error and will let everyone know if it happens again, but I think that solved my problem

OK, great. This is an unfortunate bug with the sketch build system:

Compilation fails with spurious "`No such file or directory`" error if line number of `#include` directives are changed while editor is "dirty"

### Describe the problem An Arduino IDE editor tab can be in one of two states:… - **Saved**: the contents of the file on disk matches the content in the editor buffer - The editor will always be in this state if the "**Auto save**" feature is enabled. - **Dirty**: the contents of the file on disk differs from the content staged in the editor buffer. - This is indicated by the presence of a ⬤ at the right side of the editor tab. Regardless of the state, when a compilation is triggered, it is the code in the editor buffer that must be compiled. At the start of the sketch compilation process, Arduino CLI performs a "library discovery" procedure, where the preprocessor is run tentatively on the sketch program repeatedly. If preprocessing fails, Arduino CLI parses the text of the error message. If it is a "`No such file or directory`" error from an `#include` directive, the header filename is extracted from that directive and the searches installed libraries are searched to find the one that provides that header file. The library is added to the compiler's ["search path"](https://gcc.gnu.org/onlinedocs/cpp/Search-Path.html), then the process repeated until either the preprocessing passes, or else a library can't be discovered for an `#include` directive (see [the flowchart](#library-discovery-overview) in the "**Additional context**" section of the issue if this isn't clear). 🐛 Sketch compilation fails if the sketch code staged in the editor buffer differs from the file on disk in a way that causes one `#include` directive to be present in the staged code at the line number of a different `#include` directive in the file on disk. ### To reproduce 1. Select **File > Preferences** from the Arduino IDE menus. 1. Uncheck the box next to "**Auto save**". 1. Click the "**OK** button. 1. Select **File > New Sketch** from the Arduino IDE menus. A new sketch will open in an Arduino IDE window. 1. Change the sketch code to the following: ```cpp #include <EEPROM.h> #include <SPI.h> #include <SoftwareSerial.h> #include <Wire.h> void setup() {} void loop() {} ``` **ⓘ** The fault will occur with any sketch that contains multiple consecutive `#include` directives. 1. Select **File > Save As...** from the Arduino IDE menus. 1. Save the sketch to any convenient location. 1. Select **Tools > Board > Arduino AVR Boards > Arduino Uno** from the Arduino IDE menus. **ⓘ** The fault will occur with any board. The "Arduino Uno" was picked arbitrarily for the sake of the demonstration. 1. Select **Sketch > Verify/Compile** from the Arduino IDE menus. 🙂 The sketch compiles without errors. 1. Add a blank line at the top of the sketch. ❗ Do not save the sketch. It must be in a "dirty" state to reproduce the fault. 1. Select **Sketch > Verify/Compile** from the Arduino IDE menus. 🐛 Compilation fails spuriously: ```text C:\Users\per\Documents\Arduino\Foo\Foo.ino:2:10: fatal error: EEPROM.h: No such file or directory #include <SPI.h> ^~~~~~~ ``` **ⓘ** Note that the `#include` directive for `EEPROM.h` is at line 1 in the file on disk, while it is at line 2 in the staged code, which is the position of the `#include` directive for `SPI.h` in the file on disk. 1. Add another blank line at the top of the sketch. ❗ Do not save the sketch. It must be in a "dirty" state to reproduce the fault. 1. Select **Sketch > Verify/Compile** from the Arduino IDE menus. 🐛 Compilation fails spuriously: ```text C:\Users\per\Documents\Arduino\Foo\Foo.ino:2:10: fatal error: EEPROM.h: No such file or directory #include <SoftwareSerial.h> ^~~~~~~~~~ ``` 1. Add another blank line at the top of the sketch. ❗ Do not save the sketch. It must be in a "dirty" state to reproduce the fault. 1. Select **Sketch > Verify/Compile** from the Arduino IDE menus. 🐛 Compilation fails spuriously: ```text C:\Users\per\Documents\Arduino\Foo\Foo.ino:2:10: fatal error: EEPROM.h: No such file or directory #include <Wire.h> ^~~~~~~~ ``` 1. Add another blank line at the top of the sketch. 1. Select **Sketch > Verify/Compile** from the Arduino IDE menus. 🙂 The sketch compiles without errors. **ⓘ** Note that the `#include` directive for `EEPROM.h` is at line 1 in the file on disk, while it is at line 5 in the staged code, which is the position of the `setup` function definition in the file on disk. ### Expected behavior Library discovery always works correctly, even when a sketch is in a "dirty" state. ### Arduino IDE version #### Original report [`arduino/arduino-ide@2.0.0-rc9.2`](https://github.com/arduino/arduino-ide/releases/tag/2.0.0-rc9.2) #### Last verified with arduino/arduino-ide@aa9b10d ### Operating system Windows ### Operating system version - Windows 10 - Windows 11 ### Additional context The fault does not occur if the sketch is not in a "dirty" state when compiled, whether the non-dirty state is achieved by the IDE's auto save, or by saving manually. --- Blank lines were added in the demo for the sake of simplicity, but the fault occurs regardless of what the content of the added line is. --- I didn't bisect the regression, but the fault does not occur with Arduino IDE 1.8.19. <a name="workaround"></a> #### Workaround Select **File > Save** from the Arduino IDE menus. <a name="library-discovery-overview"></a> #### Library discovery overview In case the text description of library discovery provided in the introduction is not clear, this flowchart might make it easier to understand: ```mermaid %%{ init: { 'flowchart': { 'curve': 'monotoneY' }, 'theme': 'base', 'themeVariables': { 'clusterBkg': '#ffffff', 'edgeLabelBackground': '#ffffff', 'lineColor': '#000000', 'primaryBorderColor': '#000000', 'primaryColor': '#f0f0f0', 'primaryTextColor': '#000000' } } }%% flowchart TB subgraph main[" "] direction TB compileCommand(["<code>compile</code> command"]) selectSketchFile[/"Select unprocessed sketch file"/] done{"All processed?"} preprocess[/"C++ preprocess"/] preprocessorError{"Error?"} parseError[/"Parse error message"/] includeError{"<code>#include</code> error?"} headerAvailable{"A library provides header?"} addToSearchPath["Add library to search path"] compile[["Compilation"]] failure(["Error"]) compileCommand --> selectSketchFile selectSketchFile --> done done -- "Yes" --------> compile done -- "No" --> preprocess preprocess --> preprocessorError preprocessorError -- "Yes" --> parseError parseError --> includeError includeError -- "Yes" --> headerAvailable headerAvailable -- "Yes" --> addToSearchPath addToSearchPath --> preprocess preprocessorError -- "No" --> selectSketchFile includeError -- "No" ----> failure headerAvailable -- "No" --> compile end ``` #### Additional reports - https://forum.arduino.cc/t/library-not-found-if-called-in-different-line-in-sketch/1023831 - https://forum.arduino.cc/t/ide-2-1-bug-i-m-only-adding-a-new-blank-line/1144525/1 - https://forum.arduino.cc/t/ide-2-1-bug-i-m-only-adding-a-new-blank-line/1144525/24 - https://forum.arduino.cc/t/ide-2-2-1-possible-compiler-bug/1208608 - https://forum.arduino.cc/t/blank-lines-inserted-at-start-of-sketch-causes-library-errors/1283385 - https://forum.arduino.cc/t/odd-compile-error/1307366 - https://forum.arduino.cc/t/arduino-ide-2-3-3-auto-format-error/1323275 - https://forum.arduino.cc/t/no-such-a-file-or-directory/1405019 ### Issue checklist - [X] I searched for previous reports in [the issue tracker](https://github.com/arduino/arduino-ide/issues?q=) - [X] I verified the problem still occurs when using the latest [nightly build](https://www.arduino.cc/en/software#nightly-builds) - [X] My report contains all necessary details

I apologize for any confusion it has caused you.

It only occurs when the sketch is in an unsaved state. You now know one workaround, which is to manually save the sketch when you encounter the problem. An alternative is to enable Arduino IDE's auto save feature, which will ensure your sketch is always in a saved state. I'll provide instructions you can follow to do that:

Select File > Preferences... from the Arduino IDE menus.
The "Preferences" dialog will open.
Check the box next to "Auto save" in the "Preferences" dialog.
Click the "OK" button.
The "Preferences" dialog will close.

The use of the auto save feature will of course cause you to lose control over the saving of the sketch. You will need to decide whether or not you find this acceptable. It seems the auto save behavior is increasingly the default for modern applications, so apparently most people prefer the convenience of their project always being saved over having to trigger saves manually.
