Subject: [PATCH v2] 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 sure dochecklxdialog gets run before mconf is compiled 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
