I am looking for functionality similar to this http://www.cgal.org/Manual/3.3/doc_html/cgal_manual/Boolean_set_operations_2_ref/Function_connect_holes.html.  I have already found a way to extract trapezoids using boost Polygon but I was hoping there was a method more similar to connect_holes.

I am using msvc90 with boost 1.43 and receive the same linking errors when compiling a simple trivial console project.
I can get the project to link successfully if I include a backend sink, i.e.:
#include <boost/log/sinks/text_file_backend.hpp>
This bug can be verified by declaring #define BOOST_LIB_DIAGNOSTIC and watching which libs get pulled in for linking when including or commenting out text_file_backend.hpp.

Oh! I am terribly sorry for this mistake. May I propose the attached
patch so that this will never happen again.

Steven,
I was able to compile and run my app on Windows 7.
Debugging using Visual Studio 2008 and using Boost 1.43.0 with the patch
from https://svn.boost.org/trac/boost/ticket/4257
The value of l at line 56 of boost/archive/impl/basic_binary_archive.ipp is
I = 369098752;
file_signature = ""
Line 56:   if(l == std::strlen(BOOST_ARCHIVE_SIGNATURE())) {      Fails!
Line  70:  if(file_signature != BOOST_ARCHIVE_SIGNATURE()) is true so, the
archive_exception::invalid_signature is thrown on line 73.
On my Window 7 PC,
sizeof(size_t) == 4
sizeof(library_version_type)  could not find definition of
library_version_type
sizeof(int) == 4
sizeof(long) == 4
sizeof(float) == 4
sizeof(double) == 8
Thanks,
Robert

indicating that you're trying to read the archive on a
little endian machine, when it was written on a big
endian machine.

It's boost::archive::library_version_type defined in

Steven,
Ok, thanks.  I was just wondering about that.
I guess I will have to go back to debugging it on my embedded PowerPC with
gcc and Eclipse.
I will try the same tests on the PowerPC.
Thanks, Robert
