Fails to build on RHEL-5:
CC convert-dtsv0-lexer.lex.o
cc1: warnings being treated as errors
convert-dtsv0-lexer.lex.c:693: warning: no previous prototype for ‘yylex’
make: *** [convert-dtsv0-lexer.lex.o] Error 1
Removing -Werror from the Makefile gets me a bit further:
CC dtc-lexer.lex.o
dtc-lexer.lex.c:683: warning: no previous prototype for ‘yylex’
dtc-lexer.l: In function ‘push_input_file’:
dtc-lexer.l:192: warning: implicit declaration of function
‘yypush_buffer_state’
dtc-lexer.l:192: warning: nested extern declaration of ‘yypush_buffer_state’
dtc-lexer.l: In function ‘pop_input_file’:
dtc-lexer.l:201: warning: implicit declaration of function
‘yypop_buffer_state’
dtc-lexer.l:201: warning: nested extern declaration of ‘yypop_buffer_state’
CC dtc-parser.tab.o
LD dtc
dtc-lexer.lex.o: In function `push_input_file':
/home/buildbot/git/dtc/dtc-lexer.l:192: undefined reference to
`yypush_buffer_state'
dtc-lexer.lex.o: In function `pop_input_file':
/home/buildbot/git/dtc/dtc-lexer.l:201: undefined reference to

collect2: ld returned 1 exit status
make: *** [dtc] Error 1
I guess the flex version shipped with RHEL-5 is too old.
$ rpm -qf $(which lex)
flex-2.5.4a-41.fc6
cheers,
