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

I would suggest to try it with a small piece of code in an independent project. This project can easily be migrated to VC2005. On 11/14/07, Olivier Tournaire wrote:

Same problem with 1.34.1. I really think that this errors come from my compiler. I sould try with VC 2005, but it is very difficult for me and all my projects ...

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,

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);

Regards
