Subject: erofs-utils: use $EROFS_UTILS_VERSION, if set, as the version
X-Git-Tag: v1.8.2~20
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c469131828a5062eeb3047309cf69af55f6c7db4;p=platform%2Fupstream%2Ferofs-utils.git

erofs-utils: use $EROFS_UTILS_VERSION, if set, as the version

This lets downstreams embed the unpolluted downstream version;
when building the Debian package (from gbp) the resulting binary yields
  $ mkfs.erofs
  <E> erofs: missing argument: FILE
  mkfs.erofs 1.8.1-fead89d91-dirty
  Try 'mkfs.erofs --help' for more information.

Now, d/rules can
  export EROFS_UTILS_VERSION := $(shell IFS="$$IFS()" read -r _ v _ < debian/changelog; echo "$$v")
yielding
  $ mkfs.erofs
  <E> erofs: missing argument: FILE
  mkfs.erofs 1.8.1-1
  Try 'mkfs.erofs --help' for more information.
