From 04aa90b529ee45c5ee88997bc214202e07b26979 Mon Sep 17 00:00:00 2001 From: Wang Nan Date: Tue, 1 Sep 2015 05:56:45 +0000 Subject: [PATCH] perf build: Fix Intel PT instruction decoder dependency problem I hit following building error randomly: ... /bin/sh: /path/to/kernel/buildperf/util/intel-pt-decoder/inat-tables.c: No such file or directory ... LINK /path/to/kernel/buildperf/plugin_mac80211.so LINK /path/to/kernel/buildperf/plugin_kmem.so LINK /path/to/kernel/buildperf/plugin_xen.so LINK /path/to/kernel/buildperf/plugin_hrtimer.so In file included from util/intel-pt-decoder/intel-pt-insn-decoder.c:25:0: util/intel-pt-decoder/inat.c:24:25: fatal error: inat-tables.c: No such file or directory #include "inat-tables.c" ^ compilation terminated. make[4]: *** [/path/to/kernel/buildperf/util/intel-pt-decoder/intel-pt-insn-decoder.o] Error 1 make[4]: *** Waiting for unfinished jobs.... LINK /path/to/kernel/buildperf/plugin_function.so This is caused by tools/perf/util/intel-pt-decoder/Build that, it tries to generate $(OUTPUT)util/intel-pt-decoder/inat-tables.c atomatically but forget to ensure the existance of $(OUTPUT)util/intel-pt-decoder directory. This patch fixes it by adding $(call rule_mkdir) like other similar rules.
