From: Bjørn Forsman Date: Fri, 2 Jan 2015 23:58:47 +0000 (+0100) Subject: Makefile: pass host PKG_CONFIG_PATH at "make menuconfig" time X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0515fe45661b6d320f8d2071df27ce64bfce2ab1;p=buildroot.git Makefile: pass host PKG_CONFIG_PATH at "make menuconfig" time Buildroot unexports PKG_CONFIG_PATH in the top-level Makefile for purity reasons. But it has an unfortunate side-effect in that "make menuconfig" will not (necessarily) be able to pick up ncurses via host pkg-config, breaking "make menuconfig" on systems where ncurses is installed in a non-standard location. This patch saves the original PKG_CONFIG_PATH variable in HOST_PKG_CONFIG_PATH and restores the original PKG_CONFIG_PATH variable only in the sub-processes that builds the various menuconfig/nconfig/... targets. (PKG_CONFIG_PATH has to be placed in front of the make command so that it propagates to sub-processes. If given as an argument, it doesn't work.) Signed-off-by: Bjørn Forsman Acked-by: "Yann E.
