kconfig/lxdialog: rationalise the include paths where to find {.n}curses{,w}.h

        echo '-I/usr/include/ncursesw -DCURSES_LOC="<ncursesw/curses.h>"'

        echo '-I/usr/include/ncurses -DCURSES_LOC="<ncurses/curses.h>"'
    [...]

This is merely inconsistent:
  - adding the full path to the directory in the -I directive,
  - especially since that path is already a sub-path of the system
    include path,
  - and then repeating the sub-path in the #include directive.

Rationalise each include directive:
  - only use the filename in the #include directive,
  - keep the -I directives: they are always searched for before the
    system include path; this ensures the correct header is used.

Using the -I directives and the filename-only in #include is more in
line with how pkg-config behaves, eg.:
    $ pkg-config --cflags ncursesw
    -I/usr/include/ncursesw

This paves the way for using pkg-config for CFLAGS, too, now we use it

menuconfig: fix extended colors ncurses support

The ncurses library allows for extended colors. The support for extended
colors support depends on wide-character support. ncurses headers
enable extended colors (NCURSES_EXT_COLORS) only when wide-character
support is enabled (NCURSES_WIDECHAR).

The "make menuconfig" uses wide-character ncursesw library, which can be
compiled with wide-character support, but does not define NCURSES_WIDECHAR
and it's using headers without wide-character (and extended colors) support.

This fixes problems with colors on systems with enabled extended colors
(like PLD Linux). Without this patch "make menuconfig" is hard to use.

The correct syntax for gcc -x is "gcc -x assembler", not

is what is documented in the manual page and thus what gcc wrappers

This isn't a cosmetic change. The missing space prevents icecream from

miscompilations.

Besides me, credits go to Michael Matz and Dirk Mueller for

8 years agoapplet_tables: save space by removing applet name offsets
Ron Yorston [Tue, 29 Mar 2016 22:42:05 +0000 (00:42 +0200)]
applet_tables: save space by removing applet name offsets

The array applet_nameofs consumes two bytes per applet.  It encodes

   nofork/noexec flags
   suid flags
   the offset of the applet name in the applet_name string

Change the applet_table build tool to store the flags in two separate
arrays (applet_flags and applet_suid).  Replace applet_nameofs[] with a
smaller version that only stores a limited number of offsets.

This requires changes to the macros APPLET_IS_NOFORK, APPLET_IS_NOEXEC
and APPLET_SUID.

   According to Valgrind the original find_applet_by_name required
   353 cycles per call, averaged over all names.  Adjusting the number
   of known offsets allows space to be traded off against execution time:

      KNOWN_OFFSETS     cycles     bytes (wrt KNOWN_OFFSETS = 0)

           0             9057        -
           2             4604       32
           4             2407       75
           8             1342       98
          16              908      130
          32              884      194

   This patch uses KNOWN_OFFSETS = 8.

v2:
   Remove some dead code from the applet_table tool;
   Treat the applet in the middle of the table as a special case.

v3:
   Use the middle applet to adjust the start of the linear search as
   well as the last applet found.

v4:
   Use an augmented linear search in find_applet_by_name.
   Drop the special treatment of the middle name from get_applet_name:
   most of the advantage now derives from the last stored value.

v5:
   Don't store index in applet_nameofs, it can be calculated.

v6:
