I'd like to report a possible bug/limitation in automake and it's use
with flex. It seems that ylwrap strips out or otherwise does not
recognize the --header-file=foo.h option provided in AM_LFLAGS. My
successful useage under 1.9 has been (obviously since ylwrap was not
called due to there only being one parser):
BUILT_SOURCES = grammar.h
AM_YFLAGS = -d -p foo_parser_
AM_LFLAGS= -Pfoo_parser_ -olex.yy.c --header-file=rules.h
foo_SOURCES = \
rules.ll \
grammar.yy
make...
/bin/sh ../config/ylwrap rules.ll lex.yy.c rules.cc -- flex -
Ppass_parser_ -olex.yy.c --header-file=rules.h
...
grammar.yy:15:21: error: rules.h: No such file or directory
Is this a bug? Or am i using automake incorrectly here?
Thanks,
Mike Tegtmeyer
