Subject: [dpdk-stable] [PATCH 3/7] Revert "Revert "Revert "build/pkg-config: output drivers first for static build"""
Date: Mon, 22 Mar 2021 12:21:31 +0100
Message-ID: <20210322112135.3420072-4-christian.ehrhardt@canonical.com> (raw)
In-Reply-To: <20210322112135.3420072-1-christian.ehrhardt@canonical.com>

This reverts commit 906e935a1fd1f6cf01ff12d70c2f040aa91984c6.
This series changes linking behavior in 19.11.x and thereby should stay
out. It breaks - for example - a rebuild of OVS 2.13 or builds
of later OVS 2.13.x stable releases.

Reverting this drops the two following 19.11.7 changes which need to be
re-created in the new (old) place of meson.build

-#   Libs   Libs.private   Requires   Requires.private
-# The fields Requires* are for package names.
-# The flags of the DPDK libraries must be defined in Libs* fields.
-# However, the DPDK drivers are linked only in static builds (Libs.private),
-# and those need to come *before* the regular libraries (Libs field).
-# This requirement is satisfied by moving the regular libs in a separate file
-# included in the field Requires (after Libs.private).
