This warning occurs in release mode builds on some compilers. This is an
annoying warning that is easy to fix, but pushing it upstream to vml in
the vxl style of coding will take longer than I have time to address at
the moment.
ITKv4/Modules/ThirdParty/VNL/src/vxl/core/vnl/vnl_diag_matrix.h:82:47:
warning:
unused parameter 'j' [-Wunused-parameter]
inline T& operator () (unsigned i, unsigned j) {
The quick robust but ugly way would be:
- assert(i == j);
+ assert(i == j); (void)j;
==========
ITK way of doing it would be:
//The vxlDebugStatement is to be used to protect code that is only valid
in debug mode
#if defined( NDEBUG )
# define vxlDebugStatement(x)
#else
# define vxlDebugStatement(x) x
#endif
inline T& operator () (unsigned i, unsigned itkDebugStatement(j) ) {
==========
Simple patchset sent to gerrit http://review.source.kitware.com/#/c/13966/
for critiques. I would appreciate it if a vxl expert could push this
upstream.
