[eigen] LevenbergMarquardt VC2008 error

["SHIROKOBROD Oleg" <Oleg.Shirokobrod@xxxxxxxxxx>]

Hi Thomas,

 

I think you are the right person for asking. While compiling my NonlinearLeastSquareFitterTest with MSVS 2008,  I get the following error message

 

Compiling...

NonlinearLeastSquareFitterTest.cpp

eigen3\eigen\src\core\transpose.h(120) : error C2440: 'return' : cannot convert from 'const double *' to 'double *'

Could you fix it?        

Thanks,
