+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.
