Re: [Boost-users] Fwd: bind, template member function and thread

Olivier, I did my tests with boost 1.34.1 and VC Express 2005. Can you try at least with the version 1.34.1 of boost and your current compiler? Best Regards, Ovanes

Hi,

Does someone has an issue to this problem ? I am under VC7.1 with boost 1.33.1

And the function template ComputeRadiometries is the member of the Profile class? Can you please write the second error?

Yes. Please note that ComputeRadiometries is a member of the Profile class, and that I call it a member of the MPPGraph class. Here is the second error :

error C2780: 'boost::_bi::bind_t,_bi::list_av_9::type> boost::bind(R (__thiscall T::* )(B1,B2,B3,B4,B5,B6,B7,B8) const,A1,A2,A3,A4,A5,A6,A7,A8,A9)' : 10 arguments attendus - 4 fournis

E:\librairies\boost_1.33.1_build\include\boost\bind\bind_mf_cc.hpp(222) : voir la déclaration de 'boost::bind'

However, where I write a simple function which encapsulates ComputeRadiometries, I got no error :

void lance_thread( boost::shared_ptr<Profile> p , boost::shared_ptr< TTImage <unsigned char> > image , eInterpolatorType typeinterp) { p->ComputeRadiometries(image,typeinterp); }

// In another member function :

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

Here is the method signature :

// in profile.hpp template <class T> void ComputeRadiometries( boost::shared_ptr< TTImage <T> > image , const eInterpolatorType type_interpolator=BICUBIC ) { // ... }

Here is how I create the threads

// ... boost::shared_ptr<Profile> p2 ( new Profile(origine+(double)i*width_sur_nb_fois_wdir,rect->GetHeightDirection(),MPPParameters_.ProfilesNbPoints_,MPPParameters_.ProfilesDistancePoints_ ) ); boost::thread t( boost::bind ( &Profile::template ComputeRadiometries<unsigned char> , p2 , image_ , BICUBIC ) );

Can you please post here som example how you function signature looks like, and how you create a new thread?

Regards, Ovanes
