From e1dc10b7b8e163ccceca6d0faff27b33517476fd Mon Sep 17 00:00:00 2001 From: Bernd Kuhls Date: Mon, 2 Oct 2023 21:51:59 +0200 Subject: [PATCH] package/dhcp: fix cross build Fixes build error Building dns library in /home/bernd/buildroot/br4/output/build/dhcp-4.4.3- P1/bind/bind-9.11.36/lib/dns ./gen: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.38' not found (required by ./gen) make[4]: *** [Makefile:601: include/dns/enumtype.h] Error 1 make[3]: *** [Makefile:595: include] Error 2 with this defconfig BR2_x86_64=y BR2_PACKAGE_BUSYBOX_SHOW_OTHERS=y BR2_PACKAGE_DHCP=y Please note that this build error only occurs when the target and the host system have the same arch. For example this defconfig builds fine: BR2_PACKAGE_BUSYBOX_SHOW_OTHERS=y BR2_PACKAGE_DHCP=y on a Debian 12 x86_64 host using glibc-2.36: $ /lib/ld-linux.so.2 --version ld.so (Debian GLIBC 2.36-9+deb12u1) stable release version 2.36. The error occurs since buildroot commit 34f8d874ee which bumped glibc from 2.37 to 2.38.
