Hi folks,
I'm compiling a simple test application for boost::multi_index extractor
operator and getting the warning below. Count as a bug report.
OS: Ubuntu linux 7.10
Compiler: g++ (GCC) 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2)
Compile flags: Shown below.
Thanks,
Emre Turkay

Hi Emre, the problem you describe is reported as a GCC bug at

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32395

but it doesn't seem to have been solved yet. Anyway, The Boost 1.35 version
of Boost.MultiIndex has been tweaked to shut this warning up. You can
download a daily snapshot of the SVN trunk at:

http://boost-consulting.com/boost.tar.bz2

While you wait for Boost 1.35 to come out you can patch your local copy
of Boost (I assume it's Boost 1.34.1) by replacing lines 798 and following of
boost/multi_index/ordered_index.hpp:

  struct link_info
  {
    ordered_index_side       side;
    ordered_index_node_impl* pos;
  };

with the following:

  struct link_info
  {
    link_info():side(to_left){}

    ordered_index_side side;
    node_impl_pointer  pos;
  };

Hope this helps. Thanks for reporting the problem and for using
Boost.MultiIndex,
