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<R,boost::_mfi::cmf8<R,T,B1,B2,B3,B4,B5,B6,B7,B8>,_bi::list_av_9<A1,A2,A3,A4,A5,A6,A7,A8,A9>::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
