I'm trying to package something that explicitly requires GNU bison. So I
thought... let's do 'USE_GNU_TOOLS+=yacc' and hope tools.mk does everything
else. But I was wrong.
If I do that, tools.mk only tries to provide a yacc utility that is good
enough to work for most programs. But I want the GNU flavour of it, not one
that may work. So I find this confusing...
What about changing tools.mk so that USE_GNU_TOOLS _always_ picks up a GNU
variant (it could check if the base system provides it to avoid
reinstallation), and add a USE_TOOLS that can be used to mark a package as
needing some special tools?
I.e., you do:
USE_TOOLS+= yacc lex
then, tools.mk will try to provide a yacc and a lex that work, as it actually
But if you do:
USE_GNU_TOOLS+= yacc lex
then you always get the GNU versions.
Or maybe make USE_GNU_TOOLS recognize 'bison' as another "different" utility
that explicitly pulls bison in?
