kbuild: Fix gcc -x syntax

2012-10-12T20:50:17+00:00

commit b1e0d8b70fa31821ebca3965f2ef8619d7c5e316 upstream.

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.

kconfig: fix check-lxdialog for DLL platforms

2012-07-04T16:28:14+00:00

Import libraries on Cygwin and MinGW/MSYS use the .dll.a suffix, so
checking this suffix is necessary to make sure ncurses will still be
found when built without static libraries.

kconfig: check ncursesw headers first in check-lxdialog

2012-07-04T16:26:35+00:00

Commit 8c41e5e363db55d91aa3b1cdce4ab02ad9821de7 added a check for
ncursesw/curses.h for the case where ncurses and ncursesw are build
separately but only one is installed.  But if both are installed,
the headers ncurses/curses.h and ncursesw/curses.h differ, and since
libncursesw will be found first, so should ncursesw/curses.h.

Some variables were being set but never used, which was triggering

kconfig: fix menuconfig on debian lenny

2010-09-20T12:09:31+00:00

In 60f33b8 (kconfig: get rid of stray a.o, support ncursesw, 2006-01-15),
support to link menuconfig with ncursesw library was added.  To compute
the linker command option -l, we check "libncursesw.{so,a,dylib}" to allow
ncursesw to be used as a replacement ncurses.  However, when checking what
header file to include, we do not check /usr/include/ncursesw directory.

Add /usr/include/ncursesw to the list of directories that are checked.
With this patch, on my Debian Lenny box with libncursesw5-dev package but
not libncurses5-dev package, I can say "make menuconfig".

menuconfig: truncate list items

2010-06-03T11:41:02+00:00

Truncate list items to fit in a single line, otherwise those items
which have long prompts will cover some other items.

This follows the behavior of menubox.

menuconfig: fix to center checklist correctly in a corner case

2010-06-03T11:41:02+00:00

Run:
	make ARCH=arm menuconfig

And then select "System Type" -> "ARM system type". The kconfig
"choice" menu at this point looks empty.

It's because config ARCH_S3C2410 has a long prompt:

config ARCH_S3C2410
        bool "Samsung S3C2410, S3C2412, S3C2413, S3C2416, S3C2440, S3C2442, S3C2443, S3C2450"
	...

menuconfig centers the checklist according to this prompt without
considering the width of the list, and then things get wrong.

menuconfig: add support to show hidden options which have prompts

2010-04-14T13:34:19+00:00

Usage:
  Press  to show all config symbols which have prompts.

Quote Tim Bird:

| completely missing until I disable CC_OPTIMIZE_FOR_SIZE.

| unsettable unless the SIZE option is disabled?  I'm
| not a Kconfig guru...

I myself found this useful too. For example, I need to test
ftrace/tracing and want to be sure all the tracing features are
enabled, so I  enter the "Tracers" menu, and press  to
see if there is any config hidden.

I also noticed gconfig and xconfig have a button "Show all options",
but that's a bit too much, and I think normally what we are not
interested in those configs which have no prompt thus can't be
changed by users.

Exmaple:

      --- Tracers
      -*-   Kernel Function Tracer
      - -     Kernel Function Graph Tracer
      [*]   Interrupts-off Latency Tracer
      - -   Preemption-off Latency Tracer
      [*]   Sysprof Tracer

Here you can see 2 tracers are not selectable, and then can find
out how to make them selectable.
