[libvirt] [PATCH] build: fix linking with systemtap probes

Commit 34e8f63a3 altered virfile.o to drag in additional symbols, which in turn led to pulling in other .o files and eventually causing a link failure when systemtap probes are enabled, such as: ./.libs/libvirt_util.a(libvirt_util_la-event_poll.o): In function `virEventPollRunOnce': /home/dummy/libvirt/src/util/event_poll.c:614: undefined reference to `libvirt_event_poll_run_semaphore' ./.libs/libvirt_util.a(libvirt_util_la-event_poll.o):(.note.stapsdt+0x24): undefined reference to `libvirt_event_poll_add_handle_semaphore' Even though libvirt_iohelper and libvirt_parthelper don't directly use the portion of virfile.o that drags in probing, it was easier to satisfy the linker and get the build back up, than to figure out whether it is even possible or worth trying to disentangle the mess. * src/Makefile.am (libvirt_iohelper_LDADD) (libvirt_parthelper_LDADD): Use libvirt_probes.lo when needed. --- Pushing under the build-breaker rule, in response to: https://www.redhat.com/archives/libvir-list/2012-October/msg01679.html src/Makefile.am | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/src/Makefile.am b/src/Makefile.am index 187663f..1f32263 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -1631,6 +1631,9 @@ libvirt_iohelper_LDFLAGS = $(WARN_LDFLAGS) $(AM_LDFLAGS) libvirt_iohelper_LDADD = \ libvirt_util.la \ ../gnulib/lib/libgnu.la +if WITH_DTRACE_PROBES +libvirt_iohelper_LDADD += libvirt_probes.lo +endif libvirt_iohelper_CFLAGS = $(AM_CFLAGS) endif @@ -1645,6 +1648,9 @@ libvirt_parthelper_LDADD = \ $(LIBPARTED_LIBS) \ libvirt_util.la \ ../gnulib/lib/libgnu.la +if WITH_DTRACE_PROBES +libvirt_parthelper_LDADD += libvirt_probes.lo +endif libvirt_parthelper_CFLAGS = $(LIBPARTED_CFLAGS) $(AM_CFLAGS) endif -- 1.7.11.7
