[PATCH] perf tools: Fix bison-related build failure on CentOS 6

[Namhyung Kim]

The YYLTYPE_IS_TRIVIAL is defined in the Build file, but unlike
pmu-bison.c, gcc complained about it for parse-events-bison.c:

any clue why is that? cant see why Fedora is not complaining
over the same sources and RHEL6 fails..

I have no idea.  I just found it during build test using containers,
and had no chance to look into the bison code..

Thanks,

Ok, so this helps, it builds now on RHEL6.6, which was something I and
Jiri were chasing, but why has it complained for one and not the other?
Ideas?

Well, applied tested it on both rhel7, fedora21 and rhel6.6, seems to work,
have it in my perf/core branch at git.kernel.org, that branch now builds on
rhel6.6, after fixing issues with several patches that were making it shadow
some functions (util.h's error(), etc).

If we can get a better message for that, figuring out what that
_IS_TRIVIAL thingy does....

looks like the RHEL6 gcc/cpp treats this as an error which
is not maskable by '-w' option

anyway I checked the git log history and I'm not sure
why we event have this define, it was added by Ingo
and carried by ever since:

  65f3e56e0c81 perf tools: Remove auto-generated bison/flex files

probably because of the fail I see if I remove it from pmu-bison.o build:

  util/pmu-bison.c:613:6: error: "YYLTYPE_IS_TRIVIAL" is not defined

ok, seem's the patch is right and the 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

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:

  <command-line>: 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."
