  When the build option has '-DRTE_LIBRTE_IEEE1588=1',
the announce of timesync functions will be build.
However the dpdk_conf doesn't hav RTE_LIBRTE_IEEE1588
so that the file dpaa2_ptp.c will not be build.
It cause the build error.
This patch fixes it by adding set for dpdk_conf.

The "RTE_LIBRTE_IEEE1588=1" can fail,
all places looking for "#ifdef RTE_LIBRTE_IEEE1588", so a
"-Dc_args=-DRTE_LIBRTE_IEEE1588" is more likely,
but why not "-Dc_args=-DRTE_LIBRTE_IEEE1588=666"

Can't we just remove the conditional build:

  -if dpdk_conf.has('RTE_LIBRTE_IEEE1588')
  -       sources += files('mc/dprtc.c')
  -       sources += files('dpaa2_ptp.c')
  -endif
  +sources += files('mc/dprtc.c')
  +sources += files('dpaa2_ptp.c')

The announce of timesync functions are in the #define DRTE_LIBRTE_IEEE1588
While the define of the functions are in the file 'dpaa2_ptp.c'.
So they should be both build or not build by whether the build option -DRTE_LIBRTE_IEEE1588=1 or not.
So it seems not a good idea that remove the conditional.

timesyncs_* dev_ops functions defined but not used is not big problem, 
only can increase the library size.

I believe more concern is on:
'RTE_PMD_REGISTER_DPAA2_OBJECT(dprtc, rte_dpaa2_dprtc_obj);'
which looks like register function to run in constructor when 
'dpaa2_ptp.c' is compiled, but not sure affect of it.
It can be possible to wrap that call with 'RTE_LIBRTE_IEEE1588' ifdef, 
that should work.

It is preferred to remove the compile time flag instead of finding ways 
to make it work.

Let's wait for the dpaa2 maintainers' response, perhaps they can come 
with a smart way to remove the compile time flag.

Hi Ferruh,

    enabling  IEEE1588 causes some performance drop in the dpaa2 
performance. That is the reason, we have kept this code in compile time 
flag.


However, we will work in future to make it run-time configurable but 
that will require some code restructuring and it will be a moderate size 
work.


Regards,

Hemant

OK, thanks Hemant.

At least can it be possible to remove it from the build files, what do 
you think about wrapping those two files (or their relevant parts) with 
'RTE_LIBRTE_IEEE1588' ifdef and remove the checks from meson file?
