From c2bb66023fe3e3617f56302b6960f59545a5535c Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Stefan=20E=C3=9Fer?= Date: Tue, 14 Feb 2023 13:49:06 +0100 Subject: [PATCH] kbdcontrol: enable pre-Unicode dead key table compatibility The definition of pre-Unicode keymap ioctls will be made optional and dependent on COMPAT_FREEBSD13 in a follow-up commit to 14-CURRENT. While we generally provide ABI compatibility for older binaries on a new kernel, but not functionally extended userland programs on an old kernel, it has been specifically requested to preserve ABI compatibility for the kbdcontrol program for both these cases. Passing the kernel configuration option COMPAT_FREEBSD13 to the build of kbdcontrol will make ioctls visible to the build that are normally hidden, but required to implement compatibility with kernels that only support 8 bit characters in dead key maps. This commit is not to be merged to any previous FreeBSD version and it shall be reverted as soon as this type of ABI compatibility is no longer deemed necessary (probably before 14-STABLE is branched). This commit is a part of review D38465 and split off to allow it to be reverted using the commit ID. --- usr.sbin/kbdcontrol/Makefile | 3 +++ 1 file changed, 3 insertions(+) diff --git a/usr.sbin/kbdcontrol/Makefile b/usr.sbin/kbdcontrol/Makefile index 960671a40fe7..d2107fb86290 100644 --- a/usr.sbin/kbdcontrol/Makefile +++ b/usr.sbin/kbdcontrol/Makefile @@ -9,4 +9,7 @@ SRCS= kbdcontrol.c lex.l WARNS?= 4 CFLAGS+= -I${.CURDIR} +# temporarily added for pre-Unicode accent key API/ABI compatibility +CFLAGS+= -DCOMPAT_FREEBSD13 + .include
