I have a newly installed 64-bit Linux Debian 7.7 system where I am
trying to bring up NTP with PPS support. Using ppstest /dev/pps0 I get
the expected assert messages. I have gpsd configured and working.
Having configured and compiled NTP I get the error message:
clock type 22 invalid
On checking the config.log I see that timepps.h is missing:
root@Pixie:~/ntp/ntp-dev-4.2.7p485-RC# cat config.log | grep timepps
configure:27520: checking for sys/timepps.h
configure:28812: checking timepps.h usability
conftest.c:230:21: fatal error: timepps.h: No such file or directory
| #include <timepps.h>
configure:28812: checking timepps.h presence
conftest.c:197:21: fatal error: timepps.h: No such file or directory
| #include <timepps.h>
configure:28812: checking for timepps.h
ac_cv_header_sys_timepps_h=yes
ac_cv_header_timepps_h=no
but on searching the disk timepps.h does appear to be present, and in
the correct directory:
root@Pixie:~/ntp/ntp-dev-4.2.7p485-RC# find / -name 'timepps.h'
/usr/include/sys/timepps.h
/root/ntp/ntp-dev-4.2.7p485-RC/ports/winnt/ppsapi/loopback/src/timepps.h
/root/ntp/ntp-dev-4.2.7p485-RC/ports/winnt/include/timepps.h
What might be happening, please? What's wrong?
Thanks,
David
