Jiri Olsa 95f2bdbe50 perf build: Fix traceevent plugins build race ... commit 67befc6528 upstream. Ingo reported following build failure: $ make clean install ... CC plugin_kmem.o fixdep: error opening depfile: ./.plugin_hrtimer.o.d: No such file or directory /home/mingo/tip/tools/build/Makefile.build:77: recipe for target 'plugin_hrtimer.o' failed make[3]: *** [plugin_hrtimer.o] Error 2 Makefile:189: recipe for target 'plugin_hrtimer-in.o' failed make[2]: *** [plugin_hrtimer-in.o] Error 2 Makefile.perf:414: recipe for target 'libtraceevent_plugins' failed make[1]: *** [libtraceevent_plugins] Error 2 make[1]: *** Waiting for unfinished jobs.... Currently we have the install-traceevent-plugins target being dependent on $(LIBTRACEEVENT), which will actualy not build any plugin. So the install-traceevent-plugins target itself will try to build plugins, but.. Plugins built is also triggered by perf build itself via libtraceevent_plugins target. This might cause a race having one make thread removing temp files from another and result in above error. Fixing this by having proper plugins build dependency before installing plugins.
