gptp build error (missing header files fixed by Chris on local machine) about openavnu

ETHTOOL_GET_TS_INFO is defined in (/usr/include/)linux/ethtool.h.

On Debian-like systems, this would be the linux-libc-dev package. Update your installation.

Jeff,

The ETHTOOL_GET_TS_INFO ethtool query was added around version 3.5 of the kernel. Ubuntu 12.04 doesn’t support it. To use Ubuntu 12.04 you’ll need to update the kernel to support that query and generate ‘sanitized’ headers from the kernel source. Run ‘make headers_check’ and then ‘make INSTALL_HDR_PATH= headers_install’. Point the ALTERNATE_LINUX_INCPATH to .

If you need to use the 12.04 default kernel, you’ll need to remove that code. Its purpose is to map, for example, /dev/ptp0 to eth0. You could statically define a mapping and “most of the time” it will work. This is especially true when there is only one interface that supports timestamping.

To whom it may concern,
There appears to be some missing header file(s) that Chris put as the "ALTERNATE_LINUX_INCPATH=/home/chris/headers/include/

Maybe there is a prerequisite that the README does not talk about???

I get this build error under Ubuntu 12.04 LTS:

OK. That makes sense now. I am actually using kernel v3.8.0-37 which is newer than 3.5 so I think the kernel is OK (comes in Ubuntu 12.04.04 LTS). But, apt-get install linux-libc-dev gives me 3.2.0-60.91 which provides older header files (ethtool.h does not have ETHTOOL_GET_TS_INFO in it). So, I uninstalled that version and then downloaded and installed linux-libc-dev 3.8.0-35 (real close to my kernel). Now it does not see the g++ compiler.

Forgive my ignorance, but where does the above makefile live to sanitize the headers ??

Thanks,
Jeff

OK. I got it fixed. Installed linux-libc-dev v3.8.0-35, reinstalled g++ and zlib1g-dev. Builds daemon_cl.

Thanks.
