[gpsd-users] Error while compiling NAN undeclared in gpsdclient.c

[Bas van Duijnhoven]

Hi,

Im trying to compile gpsd 3.5 on my QNAP NAS (ARM CPU)

After running the scons command i get the following error:
> gpsdclient.c: In function 'true2magnetic':
> gpsdclient.c:323: error: 'NAN' undeclared (first use in this function)
> gpsdclient.c:323: error: (Each undeclared identifier is reported only 
once
> gpsdclient.c:323: error: for each function it appears in.)
> scons: *** [gpsdclient-py_2_6_7_final_0.so] Error 1
> scons: building terminated because of errors.

Any ideas?
As far as i can see i have all the build prerequisites installed 
(python, chrpath, ncurses, gcc, make etc etc)

cheers
Bas
