Subject: perf build failure on Linus's tree
Date: Thu, 3 May 2012 14:57:48 -0700	[thread overview]
Message-ID: <20120503215748.GA18995@kroah.com> (raw)

Linus's tree right now (3.4.rc5.67.gac001.dirty) gives me the following
build error when I try to build perf:
    CC util/parse-events-flex.o
<stdout>: In function ‘yy_get_next_buffer’:
<stdout>:1510:3: error: comparison between signed and unsigned integer expressions [-Werror=sign-compare]
util/parse-events.l: In function ‘parse_events_lex’:
util/parse-events.l:122:1: error: ignoring return value of ‘fwrite’, declared with attribute warn_unused_result [-Werror=unused-result]
cc1: all warnings being treated as errors

Do you really want to ensure that flex's build warnings fail the build?

thanks,

greg k-h
