2024-01-19build: Explicitly use bash for shell scriptsTom Jones1-1/+1
VPP requires bash for all shell scripts. Align shebang lines in build and test scripts to look up the location of bash rather than hard coding '/bin/bash'. Look up the location of bash for makefiles. Type: improvement Change-Id: I23b705d81d60389fa8af61c680cf0abd74f0ea24 Signed-off-by: Tom Jones <thj@freebsd.org>
2019-12-17build: Allow to override build date with SOURCE_DATE_EPOCHBernhard M. Wiedemann1-3/+8
and make host and user overridable in order to make builds reproducible. See https://reproducible-builds.org/ for why this is good and https://reproducible-builds.org/specs/source-date-epoch/ for the definition of this variable. Also switch to UTC to be independent of timezone. Also use ISO 8601 date format to be easier to parse. This is similar to c9f40227836b827b71a6cbc4744d4b7151b2fcef and df82ec8fe7d91467c8b479bba74c761c0a6ffc59 which was lost in the move away from automake. Note: This date call is designed to work with different flavors of date (GNU, BSD and others). If only GNU (Linux) support is needed, the patch can be simplified. This PR was done while working on reproducible builds for openSUSE. Type: fix Change-Id: If4cab12320e6b5fcb1f2842fac5d745b33b01ed7 Signed-off-by: Bernhard M. Wiedemann <bwiedemann@suse.de>
