Bjørn, All,
On 2015-01-03 00:58 +0100, Bjørn Forsman spake thusly:
> 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.)
