make: *** [I2C_TWI.o] Błąd 1

01:33:06 Build Finished (took 2m:629ms)

Wcześniej jakiś miesiąc temu wszystko działało ok, więc nie sprawdzałem nic tylko ten projekt. Po sprawdzeniu innych projektów nie kompilują się i jest błąd nazwa_biblioteki_dodawanej.o.
Do eraty zaglądałem już wcześniej i najprostszy program 03_Multi_LED też się nie kompiluje z powodu d_led.o.
[s]Zastanawia mnie jeszcze dlaczego biblioteka /LCD/lcd44780.c przechodzi a I2C_TWI.c już nie.[/s] po usunięciu z I2C_TWI "__ problem dalej występuje.
toolchain i plugin jest

Moim zdaniem masz pewnie coś kompletnie źle zrobione z toolchainem ...
