It is not clear to me why this happend in PIO. It compiles OK in the Arduino IDE.

BYTECLIP is defined here: https://github.com/Bodmer/TJpg_Decoder/blob/master/src/tjpgd.c#L74

and here: https://github.com/Bodmer/TJpg_Decoder/blob/master/src/tjpgd.c#L117-L122

Matbe this definition needs to be moved somewhere else in your IDE?

it works if i remove the line in platformio.ini that defines the library and removed the tjpg_decoder folder and git cloned in this repo and it worked but it is verry sketchy
