I recommend shapelib, and there is a sample here:
<http://svn.boost.org/svn/boost/trunk/libs/geometry/example/with_external_libs/x05_shapelib_example.cpp>

Writing shapelib objects is also supported, and there is a small wrapper 
around shapelib available (to write, not yet to read). It is used here:
<http://svn.boost.org/svn/boost/trunk/libs/geometry/example_extensions/gis/io/shapelib/shapelib.cpp>
