Press any key to continue... I found the patches 0001-menuconfig-mconf-cfg-Allow-specification-of-ncurses-.patch and 0002-mconf-fix-output-of-cflags-and-libraries.patch in meta-intel/recipes-kernel/linux/linux-intel. If I understand them correctly, they try to fix problems like mine, but the result seems to be wrong. The resulting mconf-cfg.sh has two if-blocks for handling $CROSS_CURSES_LIB: #!/bin/sh # SPDX-License-Identifier: GPL-2.0 set -eu cflags=$1 libs=$2 PKG="ncursesw" PKG2="ncurses" if [ "$CROSS_CURSES_LIB" != "" ]; then echo libs=\'$CROSS_CURSES_LIB\' if [ x"$CROSS_CURSES_INC" != x ]; then echo cflags=\'$CROSS_CURSES_INC\' fi exit 0 fi if [ "$CROSS_CURSES_LIB" != "" ]; then echo $CROSS_CURSES_LIB > ${libs} if [ x"$CROSS_CURSES_INC" != x ]; then echo $CROSS_CURSES_INC > ${cflags} fi exit 0 fi if [ -n "$(command -v ${HOSTPKG_CONFIG})" ]; then if ${HOSTPKG_CONFIG} --exists $PKG; then ${HOSTPKG_CONFIG} --cflags ${PKG} > ${cflags} ${HOSTPKG_CONFIG} --libs ${PKG} > ${libs} exit 0 fi if ${HOSTPKG_CONFIG} --exists ${PKG2}; then ${HOSTPKG_CONFIG} --cflags ${PKG2} > ${cflags} ${HOSTPKG_CONFIG} --libs ${PKG2} > ${libs} exit 0 fi fi [...] But only the second one seems to be correct. If I remove the first one, menuconfig works fine. My quick-and-dirty workaround is, to add a third patch on my layer to remove the first if-block, but that doesn't seems to be the correct way to fix this. Best regards Martin 106715 1 randy.macleod 2026-09-03 14:41:00 +0000 Martin, Can you check the patches that are used in linux-yocto which may be in yocto-kernel-cache. If not, ask yogesh.tyagi@intel.com or Bruce Ashfield. 106716 2 yoann.congal 2026-09-03 14:43:42 +0000 Interestingly, those were patched yesterday: https://git.yoctoproject.org/yocto-kernel-cache/commit/?id=225a864c394f4a6db5d774a45909304cdad5f2f8 106892 3 richard.purdie 2026-09-18 21:44:02 +0000 I think this may have been fixed now?
