## ## This target generates an include file that contains the git version ## string of the current branch, it must be continuously updated when ## we build in the git repo and shipped in dist tarballs to reflect the ## status of the tree when it was generated. If the tree is clean and ## the current commit is tag a starting with "v", consider this a ## release version and set an empty git version. ## ## Here is what the inline script does: ## ## First, delete any stale "version.i.tmp" file. ## ## If "bootstrap" and ".git" exists in the top source directory and the git ## executable is available, get the current git version string in the form: ## ## "latest_tag"(-"number_of_commits_on_top")(-g"latest_commit_hash")(-dirty) ## ## And store it in "version.i.tmp", if the current commit is tagged, the tag ## starts with "v" and the tree is clean, consider this a release version and ## overwrite the git version with an empty string in "version.i.tmp". ## ## If we don't have a "version.i.tmp" nor a "version.i", generate an empty ## string as a failover. ## ## If we don't have a "version.i" or we have both files and they are different, ## copy "version.i.tmp" over "version.i". This way the dependent targets are ## only rebuilt when the version string changes. ## version_verbose = $(version_verbose_@AM_V@) version_verbose_ = $(version_verbose_@AM_DEFAULT_V@) version_verbose_0 = @echo " GEN " $@; version.i: $(version_verbose)rm -f version.i.tmp; \ if (test -r "$(top_srcdir)/bootstrap" && test -r "$(top_srcdir)/.git") && \ test -x "`which git 2>&1;true`"; then \ GIT_VERSION_STR="`cd "$(top_srcdir)" && git describe --tags --dirty`"; \ GIT_CURRENT_TAG="`cd "$(top_srcdir)" && git describe --tags --exact-match --match="v[0-9]*" HEAD 2> /dev/null`"; \ echo "#define GIT_VERSION \"$$GIT_VERSION_STR\"" > version.i.tmp; \ if ! $(GREP) -- "-dirty" version.i.tmp > /dev/null && \ test "x$$GIT_CURRENT_TAG" != "x"; then \ echo "#define GIT_VERSION \"\"" > version.i.tmp; \ fi; \ fi; \ if test ! -f version.i.tmp; then \ if test ! -f version.i; then \ echo '#define GIT_VERSION ""' > version.i; \ fi; \ elif test ! -f version.i || \ test x"`cat version.i.tmp`" != x"`cat version.i`"; then \ mv version.i.tmp version.i; \ fi; \ rm -f version.i.tmp; \ true ## ## version.i is defined as a .PHONY target even if it's a real file, ## we want the target to be re-run on every make. ## .PHONY: version.i CLEANFILES = version.i.tmp ## ## Only clean "version.i" on dist-clean, we need to keep it on regular ## clean when it's part of a dist tarball. ## DISTCLEANFILES = version.i lttnginclude_HEADERS = \ lttng/health.h \ lttng/lttng.h \ lttng/constant.h \ lttng/channel.h \ lttng/domain.h \ lttng/event.h \ lttng/handle.h \ lttng/session.h \ lttng/lttng-error.h \ lttng/snapshot.h \ lttng/save.h \ lttng/load.h \ lttng/endpoint.h \ lttng/rotation.h \ lttng/location.h lttngactioninclude_HEADERS= \ lttng/action/action.h \ lttng/action/notify.h lttngconditioninclude_HEADERS= \ lttng/condition/condition.h \ lttng/condition/buffer-usage.h \ lttng/condition/session-consumed-size.h \ lttng/condition/evaluation.h lttngnotificationinclude_HEADERS= \ lttng/notification/channel.h \ lttng/notification/notification.h lttngtriggerinclude_HEADERS= \ lttng/trigger/trigger.h noinst_HEADERS = \ lttng/snapshot-internal.h \ lttng/health-internal.h \ lttng/save-internal.h \ lttng/load-internal.h \ lttng/action/action-internal.h \ lttng/action/notify-internal.h \ lttng/condition/condition-internal.h \ lttng/condition/buffer-usage-internal.h \ lttng/condition/session-consumed-size-internal.h \ lttng/condition/evaluation-internal.h \ lttng/notification/notification-internal.h \ lttng/trigger/trigger-internal.h \ lttng/endpoint-internal.h \ lttng/notification/channel-internal.h \ lttng/channel-internal.h \ lttng/rotate-internal.h \ lttng/ref-internal.h \ lttng/location-internal.h \ version.h \ version.i
