From 539f3aa2ebb42a409bc9028e38af091a86087165 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Wed, 29 Apr 2015 12:55:00 -0300 Subject: [PATCH] perf tools: Fix bison-related build failure on CentOS 6 The YYLTYPE_IS_TRIVIAL is defined in the Build file, but unlike pmu-bison.c, gcc complained about it for parse-events-bison.c: CC util/parse-events-bison.o In file included from util/parse-events.y:16: util/parse-events-bison.h:101:1: error: "YYLTYPE_IS_TRIVIAL" redefined : error: this is the location of the previous definition make[3]: *** [util/parse-events-bison.o] Error 1 Comments from Jiri Olsa: "Reason is the parse error handling that was added just recently: it adds YYLTYPE type (which is not present in pmu-bison.h), so YYLTYPE_IS_TRIVIAL gets redefined, which is ok in F20 that handle the error via '-w' option, but it's not ok for RHEL6 where the '-w' does not work for this kind of error."
