#8405: VC++ 2012 compiler warning C4189: '...' : local variable is initialized but
not referenced
-----------------------------------------------------------------------------------------+
 Reporter: Volker Schöch <vschoech@…> | Owner: barendgehrels
     Type: Bugs | Status: new
Milestone: To Be Determined | Component: geometry
  Version: Boost 1.52.0 | Severity: Problem
 Keywords: VC++ 2012, warning, C4189, local variable is initialized but not referenced |
-----------------------------------------------------------------------------------------+
 I'm using Microsoft Visual Studio 2012 to compile boost 1.52.0. I use
 compiler flag /W4. The following warnings (which we declared errors for
 our project) occur in geometry, regardless whether I'm compiling for x64
 or x86:
 {{{
 \boost_1_52_0\boost\geometry\algorithms\detail\overlay\get_turns.hpp(140):
 error C4189: 'n' : local variable is initialized but not referenced
 int const n = int(section.range_count);
 }}}
 {{{
 \boost_1_52_0\boost\geometry\strategies\cartesian\distance_projected_point.hpp(161):
 error C4189: 'fp_strategy' : local variable is initialized but not
 referenced
 fp_strategy_type fp_strategy
             = strategy::distance::services::get_similar
                 <
                     Strategy, Point, fp_point_type
>::apply(strategy);
 }}}
 Maybe it's possible to eliminate these warnings for the next boost
 version?
