[Linuxptp-users] Patch for incdefs.sh

[Chris LaRocque]

Hello

While working with buildroot, cross-compiling linuxptp for ARM I ran into;

In file included from clock.c:33:0:
missing.h:66:19: error: static declaration of ‘clock_adjtime’ follows
non-static declaration
static inline int clock_adjtime(clockid_t id, struct timex *tx)
^
In file included from missing.h:28:0,
from clock.c:33:
~/buildroot/output/host/usr/arm-buildroot-linux-uclibcgnueabihf/sysroot/usr/include/sys/timex.h:128:12:
note: previous declaration of ‘clock_adjtime’ was here
extern int clock_adjtime (clockid_t __clock_id, struct timex *__ntx)
__THROW;
^
make: *** [clock.o] Error 1

;even though uclibc 1.0.9 incorporates the feature. It is defined in
timex.h which is not found using the stock file.

Thanks for posting this fix.

- files=$(find $d -type f -name time.h)
+ files=$(find $d -regextype posix-egrep -regex ".*/time.*.h")

I would prefer this instead:

files=$(find $d -type f -name time.h -o -name timex.h)

Can you see if that works for your uClinux setup as well?

Thanks,
Richard
