Hi all,

I would like to use thread with a member function which takes parameters. Here is the code I actually use :

shared_ptr<Profile> p2 ( new Profile(origine+(double)i*width_sur_nb_fois_wdir,rect->GetHeightDirection(),MPPParameters_.ProfilesNbPoints_,MPPParameters_.ProfilesDistancePoints_ ) ); shared_ptr<Profile> p3 ( new Profile(origine+(double)(-i)*width_sur_nb_fois_wdir,rect->GetHeightDirection(),MPPParameters_.ProfilesNbPoints_,MPPParameters_.ProfilesDistancePoints_ ) ); p2->ComputeRadiometries(image_,BILINEAR); p3->ComputeRadiometries(image_,BILINEAR);

ComputeRadiometries is a template member function : template <class T> bool ComputeRadiometries( boost::shared_ptr< TTImage <T> > image , const eInterpolatorType type_interpolator=BICUBIC )

This compiles fine : boost::function, eInterpolatorType)> f;

But, this does not : f = &Profile::ComputeRadiometries;

This is incorrect. How should the compiler know which function address do you mean? The correct way would be: f=&Profile::template ComputeRadiometries<unsigned int>;

This does not seem to work. The compiler error is : error C2440: '=' : impossible de convertir de 'overloaded-function' en 'boost::function<Signature>' with [ Signature=bool (Profile *,boost::shared_ptr,eInterpolatorType) ] I would like to use boost::bind in order to call ComputeRadiometries with a

...

thread.

Can you help ?
