build system: allow monochrome 'make menuconfig'

2022-11-16T14:43:33+00:00

'make menuconfig' uses a hardcoded colour palette which may be difficult to read. Add support for the 'COLORS' environment variable. Setting this to '0' will cause 'make menuconfig' to be displayed in black and white. (GitHub issue #273)

build system: silence compiler warning

2022-11-08T08:47:44+00:00

The compiler in MSYS2 warns that strcasecmp(3) isn't declared in scripts/kconfig/lxdialog/checklist.c. Add the appropriate include to silence this warning.

Provide PDCurses source for w64devkit build

2022-11-07T13:49:52+00:00

w64devkit doesn't ship a curses library. Provide a cut-down copy of PDCurses which is sufficient to allow 'make menuconfig' to work in w64devkit.

kconfig/lxdialog: get ncurses CFLAGS with pkg-config

2016-04-04T03:59:15+00:00

This makes "make menuconfig" also work on systems where ncurses is not installed in a standard location (such as on NixOS). This patch changes ccflags() so that it tries pkg-config first, and only if pkg-config fails does it go back to the fallback/manual checks. This is the same algorithm that ldflags() already uses.

kbuild: Make scripts executable

2016-04-04T03:59:15+00:00

The Makefiles call the respective interpreter explicitly, but this makes it easier to use the scripts manually. Signed-off-by: Michal Marek Signed-off-by: Mike Frysinger

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

2016-04-04T03:59:15+00:00

The current code does this: if [ -f /usr/include/ncursesw/curses.h ]; then echo '-I/usr/include/ncursesw -DCURSES_LOC=""' elif [ -f /usr/include/ncurses/ncurses.h ]; then echo '-I/usr/include/ncurses -DCURSES_LOC=""' elif [ -f /usr/include/ncurses/curses.h ]; then echo '-I/usr/include/ncurses -DCURSES_LOC=""' [...] 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 to find the libraries.

menuconfig: optionally use pkg-config to detect ncurses libs

2016-04-04T03:59:15+00:00

When building ncurses with --with-termlib several symbols get moved from libncurses.so to libtinfo.so. Thus when linking with libncurses.so, one additionally needs to link with libtinfo.so. The ncurses pkg-config module will be used to detect the necessary libs for linking. If not available the old heuristic for detection of the ncurses libs will be used.

menuconfig: fix extended colors ncurses support

2016-04-04T03:59:15+00:00

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.

kbuild: Fix gcc -x syntax

2016-04-04T03:59:15+00:00

The correct syntax for gcc -x is "gcc -x assembler", not "gcc -xassembler". Even though the latter happens to work, the former is what is documented in the manual page and thus what gcc wrappers such as icecream do expect. This isn't a cosmetic change. The missing space prevents icecream from recognizing compilation tasks it can't handle, leading to silent kernel miscompilations. Besides me, credits go to Michael Matz and Dirk Mueller for investigating the miscompilation issue and tracking it down to this incorrect -x parameter syntax.
