[Linuxptp-users] Linuxptp steps for compilation and establishing ptp based communication

[Ronex D. <ron...@ya...>]

Hello,

I want to compile linuxptp for linux and ARM host,
But while compiling over linux it throws following errors:

grep: /usr/include/linux/net_tstamp.h: No such file or directory
gcc -Wall -DVER=1.4-00063-gbdb6a35      -c -o ptp4l.o ptp4l.c
ptp4l.c:26:30: error: linux/net_tstamp.h: No such file or directory
ptp4l.c: In function ‘main’:
ptp4l.c:343: error: ‘SOF_TIMESTAMPING_TX_SOFTWARE’ undeclared (first use in this function)
ptp4l.c:343: error: (Each undeclared identifier is reported only once
ptp4l.c:343: error: for each function it appears in.)
ptp4l.c:344: error: ‘SOF_TIMESTAMPING_RX_SOFTWARE’ undeclared (first
 use in this function)

ptp4l.c:356: error: ‘SOF_TIMESTAMPING_RAW_HARDWARE’ undeclared (first use in this function)
make: *** [ptp4l.o] Error 1



Can anyone please share the steps to compile linuxptp, and how it's supposed to use ?
I need steps for cross-compilation for arm architecture also.

Further please also suggest that if I need to establish ptp master/slave 
communication between two host in LAN, what are the steps that I need to follow for this.


Regards,Ronex

You need the kernel headers installed, and the kernel must be v3.0 or
newer. See the sections, "System Requirements" and "Installation" in
the README file.

To cross compile, set the environment variables CROSS_COMPILE and
KBUILD_OUTPUT. You set these in exactly the same way as when you
cross compiled your kernel.

On the master host:
   ptp4l -m -q -i eth0

On the slave host:
   ptp4l -m -q -i eth0 -s

Thanks,
