MORIN Date: Sat, 22 Aug 2015 17:53:13 +0000 (+0200) Subject: core/pkg-kconfig: fix configurators X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1a91c82f8a8e2de1ab95794429dfa90b78d51670;p=buildroot.git core/pkg-kconfig: fix configurators Currently, the configurators are using $($(2)_MAKE_ENV), often derived from $(TARGE_MAKE_ENV), as the environment to be set when calling the various configurators. This means that our host tools are used first, most notably pkg-config (from host-pkgconf). However, this is inherently flawed. Our pkg-config, when set for the host, only searches .pc files in $(HOST_DIR) and never ever uses the ones from the host. For example, since we do not build a host-qt, our pkg-config would not find the host's QtCore.pc et al. Consequently, on some systems (but not on others?) most of the configurators fail to build, especially the latest kernel versions, as they have been starting to use pkg-config two years ago. Fix that by filtering-out sensible values out of the environment, but only when calling the configurators.
