Hi Bruce,

First of all thanks for implementing this option, and sorry for the
delay.

A couple of minor things:

1) The project version has 3 digits, but the ABI version should have 2
- eg: should be 17.08 but right now it's 17.08.0 - given point releases
will be ABI compatible so they must not change the ABI version. In the
packaging code we use cut to chop it off:

DPDK_ABI := $(shell echo $(DEB_VERSION_UPSTREAM) | cut -d '.'  -f1-2)

Not sure how to achieve the same in a Meson script though (can it shell
out? or are there string manipulation built-ins?), sorry - just
starting to look at it.

Right now the rte_config option allows the user to completely override
the version - I'm fine with having a single boolean provided this
change is applied, it simplifies packaging a bit, but if it's easier
for you to just accepted a version instead of a boolean it's fine as
well, as you prefer

2) When the option is true, it should not generate a symlink with the
ABI "revision", as the first digit is really not the revision, so it
does not make much sense. Worse, it will stop 2 versions being co-
installable (which was the whole point :-) ), as, eg, 17.02, 17.05 and
17.08 will all ship a libfoo.so.17 symlink. I can fix it in the
packaging, but I don't think it should be generated upstream at all
when this option is enabled.

IOW, the following is the current result:

$ ls -l debian/librte-ethdev17.08/usr/lib/x86_64-linux-gnu/
total 72
lrwxrwxrwx 1 lboccass lboccass    24 Sep 13 11:50 librte_ethdev.so.17 -> librte_ethdev.so.17.08.0
-rw-r--r-- 1 lboccass lboccass 71672 Sep 13 11:50 librte_ethdev.so.17.08.0

The expected result would be to create a single file "librte_ethdev.so.17.08" instead.

Kind regards,
Luca Boccassi
