Subject: [Buildroot] [PATCH 2/3] package/dpdk: add option to disable target installation
Date: Mon, 13 Apr 2026 17:11:47 +0200	[thread overview]
Message-ID: <20260413151148.42226-3-maxime@leroys.fr> (raw)
In-Reply-To: <20260413151148.42226-1-maxime@leroys.fr>

Introduce BR2_PACKAGE_DPDK_INSTALL_TARGET (default y) to control
whether DPDK is installed on the target. When disabled, DPDK is
kept in staging only for build-time use.

This is useful when DPDK is only needed to build applications and
is not required at runtime on the target, e.g. when an application
is linked statically against the DPDK libraries (such as grout).
