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

Hi, Does someone has an issue to this problem ? I am under VC7.1 with boost 1.33.1 2007/11/13, Olivier Tournaire :

2007/11/13, Ovanes Markarian :

...

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?

Geat, seems simpler. However, it does not compile for me (boost 1.33.1). Aot of error, but the first one seems to be the more interesting :

error C2780: 'boost::_bi::bind_t,_bi::list_av_1<A1>::type> boost::bind(R T::* ,A1)' : 2 arguments attendus - 4 fournis

(translation attempt : [...] 2 args waited, 4 given)
