OK, I see.

So, it is $(obj)/mconf.o instead of $(obj)/mconf
that should depend on $(obj)/dochecklxdialog.


Could you change line 199

  $(addprefix $(obj)/,$(lxdialog)): $(obj)/dochecklxdialog

to

  $(addprefix $(obj)/, mconf.o $(lxdialog)): $(obj)/dochecklxdialog

and send v2, please?


This will make sure dochecklxdialog is run before compiling mconf.o
in parallel building.


Thanks!

Remove libncurses5-dev or whatever it is called on your system and do:

$ make menuconfig
  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

Strange, I could not reproduce this.

As far as I tested,
"make menuconfig" invoked dochecklxdialog without this patch.



mconf depends on $(lxdiaglog) at line 184:
mconf-objs := mconf.o zconf.tab.o $(lxdialog)


$(lxdialog) depends on dochecklxdialog at line 199:
$(addprefix $(obj)/,$(lxdialog)): $(obj)/dochecklxdialog

[PATCH] kconfig: Check for libncurses before menuconfig

2017-04-09 Thread Borislav Petkov
From: Borislav Petkov 

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
