Adding the following lines to Makefile.am seems to do the trick:
BUILT_SOURCES = lex.h
CLEANFILES = lex.h
lex.h: lex.l
$(LEX) --header-file=$@ -o /dev/null $<
I think it should be possible to get the same result with the more
concise
AM_LFLAGS = --header-file=lex.h -o /dev/null lex.l
but that doesn't work for me.
