Package: arduino-core
Version: 0022+dfsg-3
Severity: important
The newest version of avr-libc in Debian has broken compiling with
arduino-core (and probably arduino as well). avr-libc 1.7.1 shipped
with a bug in the delay.h header because it did not include math.h
rendering any program which doesn't include math.h before the
util/delay.h header uncompilable. I will report this bug against
avr-libc 1.7.1-1 in order to have this fixed, but 1.7.1 also
introduces another bug when using the wiring.h library included in
Arduino, because math.h includes a definition of round which conflicts
with the wiring.h declaration at line 74 of
/usr/share/arduino/hardware/arduino/cores/arduino/wiring.h
The bug manifests itself initially as a compliation error and can be
reproduced through:
mkdir ~/tmp_arduino_bug
cd ~/tmp_arduino_bug
cat > Makefile <<'!====EOF====!'
ARDUINO_DIR = /usr/share/arduino
TARGET = Blink
#ARDUINO_LIBS = LiquidCrystal
MCU = atmega168
F_CPU = 16000000
ARDUINO_PORT = /dev/ttyUSB*
AVRDUDE_ARD_PROGRAMMER = arduino
AVRDUDE_ARD_BAUDRATE = 57600
#AVRDUDE_ARD_EXTRAOPTS = -F
include /usr/share/arduino/Arduino.mk
!====EOF====!
cp /usr/share/arduino/examples/1.Basics/Blink/Blink.pde .
make
which produces this output on unstable:

After fixing the bug in avr-libc, the error changes to:

/usr/lib/gcc/avr/4.5.3/../../../avr/include/math.h:426:15: error: expected ‘)’
before ‘>=’ token
which is caused by the macro definition of round() in wiring.h:
#define round(x) ((x)>=0?(long)((x)+0.5):(long)((x)-0.5))
commenting out this line fixes this final compliation error and the program
compiles, uploads and correctly works on the Arduino that I have.
