Subject: [PATCH] kconfig/lxdialog: get ncurses CFLAGS with pkg-config
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
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.

[This patch is already applied upstream (is part of linux v3.18):
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=be8af2d54a66911693eddc556e4f7a866670082b
I'm adding this instead of doing a full upstream kconfig sync because
there was a conflict in one of the Buildroot kconfig patches (against
linux 3.18-rc1), which I was unable to resolve. Just drop this patch next time
Buildroot kconfig is synced against upstream.

From 7285996aa0006d671bb01f0d35991d254b2b2b01 Mon Sep 17 00:00:00 2001
From: Brian Norris <computersforpeace@gmail.com>
Date: Wed, 4 Jun 2014 00:52:31 -0700
Subject: kconfig: nconfig: fix multi-byte UTF handling
Currently, Kconfig descriptions that use multi-byte UTF-8 characters
(such as MTD_NAND_CAFE) will have their menu entries dropped from the
'make nconfig' ncurses menu, and all subsequent entries in the same
window will be omitted. This seems to be due to the ncurses 'menu'
library, which does not traditionally handle UTF-8 >8-bit characters
properly.
The ncursesw library ('w' is for "wide") is written to handle these
UTF-8 characters, and is practically a drop-in replacement at the source
level. Use it by default, if available.
