From: Eric Blake Date: Thu, 20 Feb 2014 13:56:42 +0000 (-0700) Subject: maintainer-makefiles: use $(SED) for syntax check X-Git-Tag: v1.0~7434 X-Git-Url: https://gitweb.git.savannah.gnu.org/gitweb/?a=commitdiff_plain;h=3f51bf41;p=gnulib.git maintainer-makefiles: use $(SED) for syntax check Roman Bogorodskiy reported that attempts to use 'make syntax-check' for libvirt on a BSD host was failing, due to libvirt's use of GNU sed constructs in cfg.mk. While libvirt could be patched to use only portable sed constructs, it is also worth making sed replaceable so that any maintainer can use a consistent sed program rather than being hardcoded to the first 'sed' on $PATH. * modules/maintainer-makefile (configure.ac): Check for sane sed. * top/maint.mk: Change sed to $(SED).
