- I'm compiling a simple sketch that reads values from an analog input and activates a buzzer on a digital input.
- working on an Arduino uno.
- the sketch compiles and runs fine on windows and arch linux using the Arduino IDE.
I recently tried to start working with Arduino-mk, I tried to compile the said sketch and got the following compiler error (analogVal is the variable holding the analogRead):
/usr/bin/avr-gcc -mmcu=atmega328p -Wl,--gc-sections -Os -o /home/niv/Gits/bin/uno/maglove/maglove.elf

make: *** [/home/niv/Gits/bin/uno/maglove/maglove.elf] Error 1
make: Target 'all' not remade because of errors.
I am not very experienced with Arduino yet, and google has failed me in finding this error or any keyword from it in the context of Arduino uno.
thanks.
