Libaries not found on linux

Using Arduino Programming Questions
1

Hi People,

I recently switch to linux and I have in mind to do some stuff using arduino.

I installed the ide for linux (pop os) and successfully upload the blink example on my arduino board.

But when I want to use a library i got an error : library not found :frowning:

here's a example if i want to try the midiusb example :

Arduino : 1.8.19 (Linux), Carte : "Arduino Nano, ATmega328P (Old Bootloader)"

Same stuff if I start a new empty sketch and i want to include a stock library like eeprom.h for example.

I check my preferences and the folder is ok (home/blood01/Arduino/) and the library i need is well installed in home/blood01/Arduino/libraries/MIDIUSB/

I saw some other topic on this forum talking about that but none gave me a solution so if someone have an idea on how i can fix that, it will be great :slight_smile:

thanks a lot

In the Arduino IDE try Tools>Manage Libraries, search for the desired library and install.

Yep i've done that (i said the library was installed in the correct path)

But I get it running, i install the ide 2.0 and the library was found and the sketch is working. It was the 1.8 ide that cause the problem.

thanks

Check FILE >> PREFERENCES for a textbox for the path.

My Linux IDE puts my libraries here:

/home/xfpd/.arduino15/libraries

I also have libraries here... (Arduino is my folder all-things-arduino)... I may have specified this, but I do not remember.

/home/xfpd/Arduino/libraries

The IDE recognizes both as valid.

Hi, I think it was the old version of Arduino IDE that mess up, I installed the IDE V2 and now it works like a charm thanks for the help :slight_smile:
