I use the last version from Dolittle (ntpclient-2007-365) and all work
quite correct,
I have a little problem on start, that it accumulate a big error on
first 20 minutes
after a reebot, then if I resync with ntp server all work ok from there.
So I'm really interested to know if someone else has this problem.
Any way, to compile I use a vmware sdk on winXp.
It's not the last version but I think that this shouldn't do the difference.
This is the step by step operation I do.
cd /home/fox/devboard-R2_01
. init_env
cd apps
tar xvf ntpclient_2007_365.tar
cd ntpclient_2007
then I use this Makefile
*******************************************************************+
AXIS_USABLE_LIBS = UCLIBC GLIBC
include $(AXIS_TOP_DIR)/tools/build/Rules.axis
INSTDIR = $(prefix)/usr/bin
CC:=cris-gcc -mlinux
CFLAGS += -Wall -Wpointer-arith -Wcast-align -Wcast-qual -Wshadow \
-Waggregate-return -Wnested-externs -Winline -Wwrite-strings \
-Wstrict-prototypes
CFLAGS += -Os
LDFLAGS= -s
#all: ntpclient
all: ntpclient adjtimex delay
ntpclient: ntpclient.o phaselock.o
adjtimex: adjtimex.o
delay: delay.o
install: ntpclient
$(INSTALL) -p -o root -g root -m 0777 ntpclient $(INSTDIR)
clean:
$(RM) ntpclient adjtimex *.o adjtimex delay
********************************************************************
then do:
make cris-axis-linux-gnu
compiling code without modification set this link error:
ntpclient.o: In function `set_time':
/home/fox/devboard-R2_01/apps/ntpclient-2007/ntpclient.c:185: undefined
reference to `clock_settime'
ntpclient.o: In function `ntpc_gettime':
/home/fox/devboard-R2_01/apps/ntpclient-2007/ntpclient.c:216: undefined
reference to `clock_gettime'
collect2: ld returned 1 exit status
make: *** [ntpclient] Error 1
So to avoid this I modified ntpclient.c inserting this lines at begin
of file
#define USE_OBSOLETE_GETTIMEOFDAY
then compile should be ok.
Take care to transfer executable to fox as binary.
Let me know if all is ok, or if you require the executable,
I can send it to you ny email.
Once program work , let me know if you have the same problem as I have.
To start at reboot time I have inserted this commands at the end of
/etc/init.d/rc
/mnt/1/fox/adjtimex -f 1524916
/mnt/1/fox/ntpclient -s -h ip_number_of_my_ntp_server
/mnt/1/fox/ntpclient -l -i 30 - ip_number_of_my_ntp_server
>/var/log/ntpclient.log&
The first one set clock frequency according to last parameters before
reboot, see file
Howto included into ntpclient distribution to compute it the first time.
