[xpressive] CVS: Spurious warnings on #include <boost/xpressive/xpressive.hpp>

I fixed these warnings and others on svn head last week. Can you sync and try again? (Note: don't look in the old cvs repository. Svn is where it's at these days.) -- Eric Niebler Boost Consulting www.boost-consulting.com The Astoria Seminar ==> http://www.astoriaseminar.com

Ah, sorry, all the website documentation was talking about CVS - eg http://www.boost.org/more/bugs.htm (and the links from there for CVS lead to getting started docs, which don't talk about CVS at all). SVN trunk (r39123) produces different warnings when I pass it the following test program at -W -Wall: #include <boost/xpressive/xpressive.hpp> int main() { boost::xpressive::sregex r1 = boost::xpressive::digit; boost::xpressive::sregex r2 = *r1; return 0; } I've attached the output bz2'd, as the original output was some 35K long.

Could you file a bug for this? Select "New Ticket" at http://svn.boost.org.

And open a ticket for this as well and assign it to me. I don't know when I'll get to it, though. -- Eric Niebler Boost Consulting www.boost-consulting.com The Astoria Seminar ==> http://www.astoriaseminar.com
This patch to "xpressive\detail\static\transforms\as_quantifier.hpp" eliminates all the warning messages: 229c229 < call(Expr const &expr, State const &, Visitor &visitor) ---
