I'm on Kubuntu 24.04. When I try to configure my intel kernel with
bitbake virtual/kernel -c menuconfig
I get the following error:

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
