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)

win32: native make menuconfig: support search

2022-11-13T15:27:03+00:00

Previously, pressing slash to search at the menu aborted the menu program ('mconf'), because regexp is not available with native mingw. Now it works, but the search is of plain string rather than regexp.

build system: try harder to detect w64devkit

2022-11-12T08:56:52+00:00

We need to build the supplied PDCurses code when using w64devkit. This was being detected by checking for the W64DEVKIT environment variable, but this is only defined if w64devkit is started via w64devkit.exe. Set W64DEVKIT ourselves if HOSTCC targets the mingw32 platform. This won't be the case when cross-compiling on Linux but will for w64devkit and MSYS2 MINGW32/64. The build won't work properly for MSYS2 MINGW32/64, but it doesn't work when using the supplied curses library either. 'make menuconfig' requires the use of MSYS2 MSYS, and HOSTCC there targets msys.

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.

win32: fix ESC/CR handling in 'make menuconfig'

2022-11-07T20:48:07+00:00

The WIN32 code in the 'mconf' build program should truncate the exit status from dialogs as if it were passed through WEXITSTATUS. The text dialog, for example, returns a status of -1 when ESC or CR is pressed. 'mconf' expects to see this as 255.

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.

win32: allow 'make menuconfig' in native builds

2022-11-07T13:49:46+00:00

'make menuconfig' is a build option to allow changes to be made to the BusyBox configuration. It's a bit friendlier than using a text editor on the .config file. Previously 'menuconfig' was only available when cross-compiling on a Linux/Unix platform. The 'mconf' build program has been ported to WIN32 so it's now able to run the 'lxdialog' program which displays the configuration dialogs. Building 'lxdialog' is somewhat awkward in MSYS2. The MINGW32/64 build environments generate WIN32 executables for 'lxdialog'. These doesn't work properly in the MSYS2 console. For 'menuconfig' to work it's necessary to run it in an MSYS build environment. This generates an MSYS binary which works in the MSYS2 console. busybox-w32 should then be built in a MINGW32/64 build environment. Doing so will generate additional copies of the build programs without a '.exe' suffix: the MSYS build environment adds '.exe' to binaries it builds. This breaks 'menuconfig'. To configure an MSYS build environment use: pacman -S gcc ncurses-devel

build system: fix breakage affecting MSYS2 build

2022-10-30T08:35:01+00:00

Upstream changes to the embedded_scripts and mkconfigs scripts resulted in busybox-w32 failing to build with MSYS2. bzip2 in MSYS2 detects stdout redirected to /dev/null as a terminal and returns a non-zero exit status. Since the test is only for the existence of bzip2, not its functionality, even an exit status of 1 is OK. Only fail if the exit status is 127.
