[PATCH 24/29] perf tools: Add build and install plugins targets

Jiri Olsa
2013-11-28T11:36:51Z

Adding 'plugins' target along with the libtraceevent.a,
so plugins are built together with traceevent library.

Adding 'install-traceevent-plugins' Makefile install target,
instructing perf to install plugins into:
$(HOME)/.traceevent/plugins
- if installed localy under $HOME
$(DESTDIR)/$(prefix)/$(libdir)/traceevent/plugins
- if installed globally

Examples:
$ make install
...
$ find ~/.traceevent/plugins/
/home/jolsa/.traceevent/plugins/
/home/jolsa/.traceevent/plugins/plugin_mac80211.so
/home/jolsa/.traceevent/plugins/plugin_kvm.so
/home/jolsa/.traceevent/plugins/plugin_scsi.so
/home/jolsa/.traceevent/plugins/plugin_sched_switch.so
/home/jolsa/.traceevent/plugins/plugin_xen.so
/home/jolsa/.traceevent/plugins/plugin_cfg80211.so
/home/jolsa/.traceevent/plugins/plugin_function.so
/home/jolsa/.traceevent/plugins/plugin_kmem.so
/home/jolsa/.traceevent/plugins/plugin_hrtimer.so
/home/jolsa/.traceevent/plugins/plugin_jbd2.so

$ sudo make install DESTDIR=/opt/perf/
...
$ find /opt/perf/lib64/traceevent/plugins/
/opt/perf/lib64/traceevent/plugins/
/opt/perf/lib64/traceevent/plugins/plugin_kvm.so
/opt/perf/lib64/traceevent/plugins/plugin_scsi.so
/opt/perf/lib64/traceevent/plugins/plugin_mac80211.so
/opt/perf/lib64/traceevent/plugins/plugin_hrtimer.so
/opt/perf/lib64/traceevent/plugins/plugin_kmem.so
/opt/perf/lib64/traceevent/plugins/plugin_jbd2.so
/opt/perf/lib64/traceevent/plugins/plugin_sched_switch.so
/opt/perf/lib64/traceevent/plugins/plugin_function.so
/opt/perf/lib64/traceevent/plugins/plugin_cfg80211.so
/opt/perf/lib64/traceevent/plugins/plugin_xen.so
