    kconfig: Check for libncurses before menuconfig · ff85a1a8
    Borislav Petkov 提交于
    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.
       ***
