perf tools: Fix parallel build (e6048fb8) · Commits · 戴 / test

Parallel builds of perf were failing for me on a 32p box, with: * new build flags or prefix util/pmu.l:7:23: error: pmu-bison.h: No such file or directory ... make: *** [util/pmu-flex.o] Error 1 make: *** Waiting for unfinished jobs.... This can pretty quickly be seen by adding a sleep in front of the bison calls in tools/perf/Makefile and running make -j4 on a smaller box i.e.: sleep 10; $(QUIET_BISON)$(BISON) -v util/pmu.y -d -o $(OUTPUT)util/pmu-bison.c Adding the following dependencies fixes it for me.
