From 886805126201b62865c31596746d3824edd43234 Mon Sep 17 00:00:00 2001 From: Bjørn Forsman Date: Sat, 3 Jan 2015 00:58:48 +0100 Subject: 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. ] Signed-off-by: Bjørn Forsman Acked-by: "Yann E.
