Petr Kulhavy
brain at jikos.cz
Mon May 15 10:25:13 UTC 2017
Add the Linux PTP Project package.
http://linuxptp.sourceforge.net/
The sysV and systemd init scripts start the daemon in automatic mode on eth0.
Signed-off-by: Petr Kulhavy <brain at jikos.cz>
--
Changes v3 -> v4:
- rename init scripts to linuxptp
- use git format of the additional patches
- use the package name in menuconfig
- clean-up the clock_nanosleep patch
Changes v2 -> v3:
- add patches to fix build issues and enable compilation on all targets
Changes v1 -> v2:
- rename package from ptp4l to linuxptp
- add EXTRA_LDFLAGS to the build cmd (suggested by Danomi Manchego)
- sysV startup script: add restart/reload code, use PID file
- clean-up empty lines and formatting issues
- license uses SPDX license code

+Subject: [PATCH] Improve detection of clock_nanosleep
+
+On some platforms compilation issues due to clock_nanosleep were occuring. The
+simple test for __uClinux__ was not sufficient.
+
+Implement full detection of clock_nanosleep in incdefs.sh by compiling a short C
+file. incdefs.sh now sets a new HAVE_CLOCK_NANOSLEEP literal. missing.h is
+changed accordingly.
+
+For proper cross-compilation makefile passes the CC variable to incdefs.sh.
