MORIN Date: Sat, 2 May 2015 09:05:00 +0000 (+0200) Subject: pkg-infra: assign BR_NO_CHECK_HASH_FOR so it is recursively-expanded X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9fa6209fd2150276c3be287399567e37dcbc862e;p=buildroot.git pkg-infra: assign BR_NO_CHECK_HASH_FOR so it is recursively-expanded Currently, assigning to BR_NO_CHECK_HASH_FOR but referencing variable assigned to later, fails. Here's a failing test-case, which is the reduced test-case of how we handle BR_NO_CHECK_HASH_FOR for now (warning added for test-case): export BR_NO_CHECK_HASH_FOR BR_NO_CHECK_HASH_FOR += $(XENOMAI_SOURCE) XENOMAI_VERSION = 2.6.4 XENOMAI_SOURCE = xenomai-$(XENOMAI_VERSION).tar.bz2 $(warning BR_NO_CHECK_HASH_FOR='$(BR_NO_CHECK_HASH_FOR)') all: Run it with simply make: $ make BR_NO_CHECK_HASH_FOR=' ' Now, change the first line to read: export BR_NO_CHECK_HASH_FOR = And we now get: $ make BR_NO_CHECK_HASH_FOR=' xenomai-2.6.4.tar.bz2' This new behaviour will be needed later for Xenomai, which handles the version string in an unusual way, so we can exclude its custom versions.
