[gpsd-users] json.c:556:6: warning: empty declaration

[Charles Curley]

I just re-cloned the repo, so as to start with a fresh build. I
then check out tag release-3.18. System is Debian 9.5 stretch.

I got three of these:

gcc -o json.os -c -pthread -Wextra -Wall -Wno-uninitialized 
-Wno-missing-field-initializers -Wcast-align -Wmissing-declarations 
-Wmissing-prototypes -Wstrict-prototypes -Wpointer-arith -Wreturn-type -O2 
-pthread -fPIC -DHAVE_SYS_TIMEPPS_H=1 -I/usr/include/dbus-1.0 
-I/usr/lib/x86_64-linux-gnu/dbus-1.0/include json.c

json.c: In function 'json_internal_read_object':
json.c:556:6: warning: empty declaration
      __attribute__ ((fallthrough));
      ^~~~~~~~~~~~~

and two of these:

gcc -o packet.o -c -pthread -Wextra -Wall -Wno-uninitialized 
-Wno-missing-field-initializers -Wcast-align -Wmissing-declarations 
-Wmissing-prototypes -Wstrict-prototypes -Wpointer-arith -Wreturn-type -O2 
-pthread -DHAVE_SYS_TIMEPPS_H=1 -I/usr/include/dbus-1.0 
-I/usr/lib/x86_64-linux-gnu/dbus-1.0/include -I/usr/include/libusb-1.0 packet.c

packet.c: In function 'nextstate':
packet.c:1065:2: warning: empty declaration
  __attribute__ ((fallthrough));
  ^~~~~~~~~~~~~

They are warning and not fatal. Still....

"When we talk of civilization, we are too apt to limit the meaning of
the word to its mere embellishments, such as arts and sciences; but
the true distinction between it and barbarism is, that the one
presents a state of society under the protection of just and
well-administered law, and the other is left to the chance government
of brute force."
