When libvirt is present before DPDK is built, some additional examples are compiled. One of them fails to build due to a missing <stdlib.h> 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 commitd17d1b6bde.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at https://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
