I keep getting library compilation error despite having the library

arwaels · May 3, 2024, 3:52pm

This happens with all libraries. i have verified the code on another pc but on mine, despite downloading the library, it keeps giving me the 'no such file or directory' compilation error.

This is an example of the error message i get:

Welcome to the forum

What is the full path to MAX30100_PulseOximeter.h on the PC that exhibits the error

ptillisch · May 3, 2024, 3:55pm

Hi @arwaels.

Unfortunately there is a bug in the sketch compiler that causes it to fail to find the library when it is installed under a path that contains this sort of character:

github.com/arduino/arduino-cli

Spurious "No such file or directory" error when library's path contains post-ASCII characters

topic: code type: imperfection

### Describe the problem If a library is installed under a path that contains… Cyrillic characters, Arduino CLI is unable to discover it. Compilation of sketches with an `#include` directive for a header file of a valid library fails with a "`No such file or directory`" error. ### To reproduce ```text $ arduino-cli version arduino-cli.exe Version: git-snapshot Commit: 4b70e023 Date: 2023-01-31T03:19:27Z $ export ARDUINO_DIRECTORIES_USER="/tmp/arduino-cli-directories/мікроконтролер" $ arduino-cli lib install Arduino_JSON [...] $ mkdir /tmp/FooSketch $ printf "#include <Arduino_JSON.h>\nvoid setup() {}\nvoid loop() {}" > /tmp/FooSketch/FooSketch.ino $ arduino-cli compile --fqbn arduino:avr:uno /tmp/FooSketch/FooSketch.ino C:\Users\per\AppData\Local\Temp\FooSketch\FooSketch.ino:1:10: fatal error: Arduino_JSON.h: No such file or directory #include <Arduino_JSON.h> ^~~~~~~~~~~~~~~~ compilation terminated. Used library Version Path Arduino_JSON 0.2.0 C:\Users\per\AppData\Local\Temp\arduino-cli-directories\мікроконтролер\libraries\Arduino_JSON Used platform Version Path arduino:avr 1.8.6 C:\Users\per\AppData\Local\Arduino15\packages\arduino\hardware\avr\1.8.6 Error during build: exit status 1 ``` ### Expected behavior Any path supported by the file system is also supported by the library discovery system ### Arduino CLI version #### Original report Arduino IDE 1.8.10 #### Last verified with 4b70e023 ### Operating system Windows ### Operating system version - 10 - 11 ### Additional context The issue is not specific to Cyrillic. For example, it also occurs with a folder named `文` or `Κώστας`. --- The fault only occurs on Windows. I am not able to reproduce it on Ubuntu 22.04 or macOS Ventura machines. --- After changing system's locale from English to Bulgarian (win1251) + restart, the compilation succeeded. Unfortunately this is not viable solution, because we have many computers (>150) and changing system locale requires admin privileges. My suggestion is that the IDE is not using the unicode version of the API when searching for libraries? --- This is more likely to occur for those using [Microsoft **Onedrive**](https://en.wikipedia.org/wiki/OneDrive) because the default location of the sketchbook is: ```text C:\Users\<username>\OneDrive\<localized "Documents">\Arduino ``` The `<localized "Documents">` in the path above is a placeholder the word "Documents" localized for the user's locale (e.g., `文档` or `Документы`) #### Additional reports - https://forum.arduino.cc/t/wemos-d1-mini-upload-problem/1084371 - https://forum.arduino.cc/t/no-such-file-or-directory-but-i-already-had-this-file/961118 - https://forum.arduino.cc/t/fatal-error-adafruit-neopixel-h-no-such-file-or-directory-but-i-have-it/1070069/15 - https://forum.arduino.cc/t/library-gives-error/1089633 - https://forum.arduino.cc/t/except-for-the-available-libraries-i-cant-use-other-libraries-even-though-i-have-downloaded-them/1092556 - https://forum.arduino.cc/t/compilation-error-due-to-library-hpp-file-not-being-detected/1127096 - https://forum.arduino.cc/t/which-arduino-nano-clone-i-have/1192347/11 - https://forum.arduino.cc/t/cannot-verify-the-arduino-code-because-the-installed-library-cannot-be-found/1215989 - https://forum.arduino.cc/t/10-fatal-error-onewire-h-no-such-file-or-directory/1223739 - https://forum.arduino.cc/t/unknown-error-for-arduino-1-8-19/1234260 - https://forum.arduino.cc/t/compilation-of-keypad-library-example-fails-key-h-no-such-file-or-directory/1241109 - https://forum.arduino.cc/t/mg135-library-please-answer/1254438 - https://forum.arduino.cc/t/i-keep-getting-library-compilation-error-despite-having-the-library/1255423 ### Issue checklist - [X] I searched for previous reports in [the issue tracker](https://github.com/arduino/arduino-cli/issues?q=) - [X] I verified the problem still occurs when using the [nightly build](https://arduino.github.io/arduino-cli/dev/installation/#nightly-builds) - [X] My report contains all necessary details

The workaround will be to configure Arduino IDE to use a different path to store libraries. I'll provide instructions you can follow to do that:

Select File > Preferences... (or Arduino IDE > Settings... for macOS users) from the Arduino IDE menus.
The "Preferences" dialog will open.
Click the "BROWSE" button on the right side of the "Sketchbook location" field.
The "Select a new sketchbook location" dialog will open.
Select a folder in any location that contains only basic ASCII characters (the characters A-z, 0-9, _, -, . are safe).
Make sure to pick a location that will be safe to store your files since, in addition to containing installed libraries, the sketchbook is a convenient location to save your sketches.
Click the "Choose" button in the "Select a new sketchbook location" dialog.
Click the "OK" button in the "Preferences" dialog.
Move all the files from the folder at the path of the old sketchbook location:
```
C:\Users\Arwar\OneDrive\المستندات\Arduino
```
to the folder at the path of the new sketchbook location you set in the Arduino IDE preferences.

Once you have finished performing the instructions above, try compiling your sketch again. Hopefully the compilation will be successful this time.

do you mean this file path?

hallowed31 · May 3, 2024, 4:11pm

While it's very likely that @ptillisch has the correct solution regarding non ASCII characters (as I am not one of the experts), may I add further to their comment about your sketchbook will go wherever you specify in the IDE under

File > Preferences

The line "Sketchbook location:" in my case reads

C:\Users\hallowed31\Documents\Arduino\sketchbook

which is important because all the libraries I add go inside a folder called libraries inside the sketchbook.
I run IDE version 1.8.10.
Thus, the full path for contributed/added libraries for me anyway if I was using the library you are trying to use would be:

C:\Users\hallowed31\Documents\Arduino\sketchbook\libraries\MAX30100lib

The folder that seems intuitive to use, in your case what you screenshot in post #4 that uses the default Arduino libraries folder, for some reason isn't the preferred way to do it. I think it had to do with ensuring your collection of libraries remains portable along with your sketchbook.

NOTE that the libraries folder INSIDE my sketchbook is a folder I manually added. As in right clicking, New>Folder and typed in libraries. I did not just cut and paste the one in the folder tree one level higher that Arduino auto creates when you install the IDE for the first time.

That was exactly the issue! I unlinked one drive, changed the folders language on onedrive then linked it again, and im not facing an error with the arduino ide or any ide which also always failed to compile. Thanks a lot.

You are welcome. I'm glad it is working now.
