LiquidCrystal_I2C.h no such file or directory

Libraries

Hi all,

I want to make some changes to a project which I created a couple of years ago however it seems that I cannot build the original project anymore.

In my project I use a LiquidCrystal_I2C library. During compilation of the project I got a bunch of complile errors (see printscreen).

Compile errors
Compile errors1060×663 267 KB

It seems that these errors are popping up because PlatformIO cannot find the header file. The linter reports “LiquidCrystal_I2C.h: no such file or directory” at the line where I include the header file.

I added the library dependancy to the platformio.ini file but with no succes.

platformio.ini:

[env:nodemcuv2]
platform = espressif8266
board = nodemcuv2
framework = arduino
upload_protocol = espota
upload_port = 192.168.2.9
upload_flags =
	--port=8266
lib_deps =
	marcoschwartz/LiquidCrystal_I2C@ ^1.1.4

I’am currently using platformio version 6.1.11

Does anybody have an idea how to solve this issue ?

Thanks in advance!

You should no be naming the variable clock because this is a built-in function in time.h (Compiler’s standard library). Fix src/LCD_Display.cpp:11 and others accordingly.
