It doesn't get issued, though. Instead, we fail the build when mconf.c doesn't find the curses.h header: HOSTCC scripts/kconfig/mconf.o In file included from scripts/kconfig/mconf.c:23:0: scripts/kconfig/lxdialog/dialog.h:38:20: fatal error: curses.h: No such file or directory #include CURSES_LOC ^ compilation terminated. Make that check a prerequisite to mconf so that the user sees the error message instead: $ make menuconfig *** Unable to find the ncurses libraries or the *** required header files. *** 'make menuconfig' requires the ncurses libraries. *** *** Install ncurses (ncurses-devel) and try again. *** scripts/kconfig/Makefile:203: recipe for target 'scripts/kconfig/dochecklxdialog' failed make[1]: *** [scripts/kconfig/dochecklxdialog] Error 1 Makefile:548: recipe for target 'menuconfig' failed make: *** [menuconfig] Error 2 Signed-off-by: Borislav Petkov Signed-off-by: Masahiro Yamada --- diff --git a/scripts/kconfig/Makefile b/scripts/kconfig/Makefile index 90a091b6ae4d..eb8144643b78 100644 --- a/scripts/kconfig/Makefile +++ b/scripts/kconfig/Makefile @@ -196,7 +196,7 @@ clean-files += config.pot linux.pot # Check that we have the required ncurses stuff installed for lxdialog (menuconfig) PHONY += $(obj)/dochecklxdialog -$(addprefix $(obj)/,$(lxdialog)): $(obj)/dochecklxdialog +$(addprefix $(obj)/, mconf.o $(lxdialog)): $(obj)/dochecklxdialog $(obj)/dochecklxdialog: $(Q)$(CONFIG_SHELL) $(check-lxdialog) -check $(HOSTCC) $(HOST_EXTRACFLAGS) $(HOSTLOADLIBES_mconf)
