Hi all, After merging the perf tree, today's linux-next build (native perf) failed like this: perf/util/pmu-flex.c:1812:1: error: unterminated comment 1812 | /** Setup the input buffer state to scan a string. The next call to yylex() will | ^ perf/util/pmu-flex.c:550:24: error: 'yy_fatal_error' used but never defined [-Werror] 550 | static void yynoreturn yy_fatal_error ( const char* msg , yyscan_t yyscanner ); | ^~~~~~~~~~~~~~ I don't know what caused this, but the above file looks fine and redoing the build works, so it may be some timing problem when doing an incremental build? -- Cheers, Stephen Rothwell
