Bison/Flex: Posix Yacc warnings

[lrosenman]

I don't know if you want to fix these, but I get this warning set on 6.4 on FreeBSD:

I looked this up once (but I can't find the link at the moment). It's not my bug. Something in the Autotools (autoconf? automake?) system is wrongly specifying -Wyacc --- I don't do it. I think this was fixed in their stuff, so you might try updating that stuff.

You could also try changing the line in src/Makefile.am to:

AM_YFLAGS = -d -Wno-yacc

and hope that the -Wno-yacc comes after the -Wyacc so it'll turn it off. I can't test this myself since I don't get the warning on any machines I have access to. If it works, I can hack in the work-around.

[lrosenman]

I'm using the latest in FreeBSD ports (head). I'll play and get back to you.

[lrosenman]

that DOES fix it.

[paul-j-lucas]

OK, I'll hack it in. (FYI: I don't specify the -y either --- their stuff does that.)

[lrosenman]

The -y isn't from me :)

Also,

[paul-j-lucas]

One issue at a time. :)

[lrosenman]

:)

[lrosenman]

want a separate issue for the readline fun?

[paul-j-lucas]

Sadly, the bison that Apple ships with Xcode is ancient:

/bin/sh ../ylwrap parser.y y.tab.c parser.c y.tab.h `echo parser.c | sed -e s/cc$/hh/ -e s/cpp$/hpp/ -e s/cxx$/hxx/ -e s/c++$/h++/ -e s/c$/h/` y.output parser.output -- bison -y -d -Wno-yacc
/bin/sh ../ylwrap lexer.l lex.yy.c lexer.c -- flex
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/bison: invalid option -- W

so this isn't a simple work-around. I could write stuff in configure.ac to probe bison to see if it accepts the -W option, but that's more work. :(

[lrosenman]

I can patch it in the FreeBSD port.

[paul-j-lucas]

Yeah, open a separate issue for readline; thanks.

[paul-j-lucas]

Wait: patch what? (And how would that help the bison that Apple ships with Xcode?)

[lrosenman]

I can patch the src/Makefile.am that the FreeBSD ports system uses to add -Wno-yacc to the AM_YFLAGS line to shut the warnings up.

And opened #5 for the readline issue.

[lrosenman]

It wouldn't help Xcode/bison... just make the FreeBSD build clean of warnings.

[lrosenman]

Oh. Well, that's your call. I can try to do a work-around on my end, but it'll take a little while.

There's no pre-written autoconf macro for probing bison, so I'll have to write one myself (and I'm not that knowledgable about m4).

[lrosenman]

NBD either way.

Thanks for looking.

[paul-j-lucas]

I have to get back to my day job. :/

[lrosenman]

Whenever, and I do too.

Actually, I just found this. I think I can replace AC_PROG_YACC (that adds the -y) with this. If the -y isn't added then bison shouldn't warn about POSIX yacc compatibility --- in which case the -Wno-yacc shouldn't be needed at all. But I'll have to try it later.

Slow work day. Try the bison-yacc-warning branch. Be sure to start from scratch. After you pull the branch:

$ git clean -xdf
$ autoreconf -fiv
$ configure
