Dear TinyOS mailing list subscribers,
I have encountered a problem in TinyOS 2 with the log function (or
any other from the math.h) on the Telosb mote. I would appreciate
any help.
$ make telosb
mkdir -p build/telosb
compiling DSCBaseAppC to a telosb binary
ncc -o build/telosb/main.exe -Os -O -mdisable-hwmul -
DCC2420_DEF_CHANNEL=24 -Wal

telosb/app.c -board= DSCBaseAppC.nc -lm
/cygdrive/c/DOCUME~1/mfo/LOCALS~1/Temp/cc6kMIB8.o: In function
`SchedulerBasicP$
TaskBasic$runTask':
app.c:(.text+0xed2): undefined reference to `log'
make: *** [exe0] Error 1
Thanks in advance
This is an issue with the underlying native C compiler. It looks like
the make system is doing the right thing: it's linking in the math
library (-lm). Try invoking ncc with -v to see if everything is being
invoked properly?
