Additional context
here is platform package version:

here is my platformio config:

Hello,

Does it compile successfully when linechart library is not included?

[laxtiz]

yes, i can compile without linechart.
here you can see i added more library from seeed, but just compile failed with linechart

[lakshanthad]

Can you attach a complete log of the output to check for all the errors?

[laxtiz]

here is a demo repo, just only linechart library.

platformio config:

[env:seeed_wio_terminal]
platform = atmelsam
board = seeed_wio_terminal
framework = arduino
lib_deps = 
        ; internal library
	Wire
	SPI
	Seeed_Arduino_LCD
	; clone from github
	https://github.com/Seeed-Studio/Seeed_Arduino_Linechart
	; linechart need this
	adafruit/Adafruit Zero DMA Library@^1.1.0

here is log:

Hello,

According to your error messages, it seems that "-std=gnu++14" should be set according to ArduinoCore-samd:
https://github.com/Seeed-Studio/ArduinoCore-samd/blob/28c4ac5980a0393f7417c773c5d8fa4f5283b379/platform.txt#L42

From platformIO config, it seems that it is set to "-std=gnu++11" and it should be changed to "-std=gnu++14":
https://github.com/platformio/platform-atmelsam/blob/67f42c69ad65f4ddbf3abfcff130bc0c9965d41d/builder/frameworks/arduino/arduino-common.py#L66

Could you maybe locally change this "platform-atmelsam/builder/frameworks/arduino/arduino-common.py" file and have a try again?

Thank you

Hello @laxtiz ,

I have tested linechart with platformio and it works. Please add the following to platformio.ini:

build_unflags = -std=gnu++11

build_flags = -std=gnu++14
