From db3d0d44acae1bda1fb5d06cbdd01f7fe3621857 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Sat, 29 Aug 2026 00:11:43 +0200 Subject: [PATCH] package/dpdk: fix example build issue when libvirt is present When libvirt is present before DPDK is built, some additional examples are compiled. One of them fails to build due to a missing include. Let's import a patch from OpenSuse, that we have submitted upstream, to fix this issue. We couldn't find any autobuilder failure for this issue, but the following defconfig allows to reproduce the failure: BR2_aarch64=y BR2_TOOLCHAIN_EXTERNAL=y BR2_TOOLCHAIN_EXTERNAL_BOOTLIN=y BR2_TOOLCHAIN_EXTERNAL_BOOTLIN_AARCH64_GLIBC_STABLE=y BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_EUDEV=y BR2_PACKAGE_DPDK=y BR2_PACKAGE_DPDK_EXAMPLES=y BR2_PACKAGE_LIBVIRT=y The problem exists since DPDK v19.11, so it has been in Buildroot since DPDK was introduced in commit d17d1b6bde95d46376c4fe93e8ca1a1f9da6c179.
