From: Jean-Baptiste Trédez Date: Wed, 7 Dec 2016 15:20:42 +0000 (+0100) Subject: linux: generate KBUILD_BUILD_TIMESTAMP date whith LC_ALL=C X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=10fc02b984f6f8c06291f94e6dbef0b289fd3880;p=buildroot.git linux: generate KBUILD_BUILD_TIMESTAMP date whith LC_ALL=C Fix kernel reproducible build if a non-C locale is used on the host system. When building the Linux kernel, scripts/gen_initramfs_list.sh does 'date -d"$KBUILD_BUILD_TIMESTAMP" +%s'. In linux.mk, Buildroot sets KBUILD_BUILD_TIMESTAMP to "$(shell date -d @$(SOURCE_DATE_EPOCH))". For example, if LANG=fr_FR.UTF-8 is defined in the host system, it does not work: - LC_ALL=C date -d"$(LC_ALL=C date)" : ok - LC_ALL=C date -d"$(LC_ALL=fr_FR.UTF-8 date)" : error LANG/LC_ALL variables exported in the main Makefiles are not passed in the $(shell ...) sub-shells.
