Hello! When you say "make kernel_menuconfig" in OpenWRT buildroot kernel configuration fails, like so: $ make kernel_menuconfig make[3]: Entering directory '/home/ta/openwrt/build_dir/target-arm_cortex-a15+neon-vfpv4_musl_eabi/linux-ipq806x/linux-4.14.134' HOSTCC scripts/kconfig/mconf.o HOSTCC scripts/kconfig/lxdialog/checklist.o HOSTCC scripts/kconfig/lxdialog/util.o HOSTCC scripts/kconfig/lxdialog/inputbox.o HOSTCC scripts/kconfig/lxdialog/textbox.o HOSTCC scripts/kconfig/lxdialog/yesno.o HOSTCC scripts/kconfig/lxdialog/menubox.o HOSTLD scripts/kconfig/mconf /usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0/../../../../x86_64-pc-linux-gnu/bin/ld: scripts/kconfig/lxdialog/checklist.o: undefined reference to symbol 'keypad' /usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0/../../../../x86_64-pc-linux-gnu/bin/ld: /lib64/libtinfow.so.6: error adding symbols: DSO missing from command line collect2: error: ld returned 1 exit status Steps to reproduce (see https://openwrt.org/docs/guide-developer/build-system/use-buildsystem) $ git clone https://github.com/openwrt/openwrt.git $ make menuconfig $ make defconfig $ make kernel_menuconfig It seems that the bug was introduced here: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=fd65465b7016dc6d9fa5c2f39cc706c231c9a089 when menuconfig no longer used pkg-config to find the ncurses libraries. Also see a related bug report from Gentoo: https://bugs.gentoo.org/457530 and the OpenWRT bug report: https://bugs.openwrt.org/index.php?do=details&task_id=2423 Thanks, Thomas
