Happy new year guys... I want to use printf statements in an application and I added the following flags in the makefile. CFLAGS += -I$(TOSDIR)/lib/printf CFLAGS += -DPRINTF_BUFFER_SIZE=250
and i have added include :#include "printf.h" header file but when i make telosb install, i get the following errors " /opt/tinyos-2.1.2/tos/chips/cc2420/lpl/DummyLplC.nc:39:2: warning: #warning "*** LOW POWER COMMUNICATIONS DISABLED ***" /opt/tinyos-2.1.2/tos/chips/msp430/adc12/Msp430Adc12ImplP.nc:68:4: warning: #warning Accessing TimerA for ADC12 /opt/tinyos-2.1.2/tos/chips/sht11/SensirionSht11LogicP.nc: In function ‘SensirionSht11LogicP__0__readSensor__runTask’: /opt/tinyos-2.1.2/tos/chips/sht11/SensirionSht11LogicP.nc:322:11: warning: variable ‘crc’ set but not used [-Wunused-but-set-variable] /opt/tinyos-2.1.2/tos/chips/msp430/adc12/AdcStreamP.nc: In function ‘AdcStreamP__nextBuffer’: /opt/tinyos-2.1.2/tos/chips/msp430/adc12/AdcStreamP.nc:191:20: warning: variable ‘tmp_count’ set but not used [-Wunused-but-set-variable] /opt/tinyos-2.1.2/tos/chips/sht11/SensirionSht11LogicP.nc: In function ‘SensirionSht11LogicP__0__performCommand’: /opt/tinyos-2.1.2/tos/chips/sht11/SensirionSht11LogicP.nc:193:19: warning: variable ‘crc’ set but not used [-Wunused-but-set-variable] /opt/msp430-46/bin/../lib/gcc/msp430/4.6.3/../../../../msp430/lib/mmpy-16/libc.a(printf.o): In function `printf': /home/cire/mm/w/tp/tinyos-2.x/tools/platforms/msp430/toolchain-46/msp430-libc-20120224/src/./stdlib/printf.c:42: undefined reference to `putchar' /opt/msp430-46/bin/../lib/gcc/msp430/4.6.3/../../../../msp430/lib/mmpy-16/libc.a(printf.o): In function `vprintf': /home/cire/mm/w/tp/tinyos-2.x/tools/platforms/msp430/toolchain-46/msp430-libc-20120224/src/./stdlib/printf.c:50: undefined reference to `putchar' collect2: ld returned 1 exit status make: *** [exe0] Error 1 Please help!
