See # https://lists.gnu.org/archive/html/autoconf-patches/2013-03/msg00000.html # https://lists.gnu.org/archive/html/bug-autoconf/2018-12/msg00001.html # In the Makefile.am you could use # $(SHELL) $(YLWRAP) $(srcdir)/foo.y \ # y.tab.c foo.c \ # y.tab.h foo.h \ # y.output foo.output \ # -- $(YACC) $(YFLAGS) $(AM_YFLAGS) # or similar. # # * Those that make use of Bison extensions. For example, # - %define api.pure requires bison 2.7 or newer, # - %precedence requires bison 3.0 or newer. # For these, in the configure.ac you will need an invocation of # gl_PROG_BISON([VARIABLE], [MIN_BISON_VERSION]) # Example: # gl_PROG_BISON([PARSE_DATETIME_BISON], [2.4]) # With this preparation, in the Makefile.am there are two ways to formulate # the invocation.
