kconfig: Check for libncurses before menuconfig
There is a check and a nice user-friendly message when the curses library is not present on the system and the user wants to do "make menuconfig". 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 <bp@suse.de> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
