Fwd: bind, template member function and thread

On 11/13/07, Olivier Tournaire
Yep, that what I tried, but it does not work. The compiler error is described below.
This is really strange. This code compiles fine:
typedef bool (Profile::*mem_fcn)(boost::shared_ptr< TTImage <unsigned
char> >, eInterpolatorType);
mem_fcn f = &Profile::template ComputeRadiometries<unsigned char>;
and the doc example states for member functions:
boost::function

But I also got errors.
Yes. The first code I posted came from the doc. The one you just gave me compiles fine. However, how can I use it to create a thread and pass parameters ? Regards Regards,

Why do you need a function instance at all?
Just use boost::bind and that's it...
Profile p;
boost::shared_ptr< TTImage<unsigned char> > image(new TTImage<unsigned
char>);
boost::thread t(
boost::bind
(
&Profile::template ComputeRadiometries<unsigned char>
, p
, image
, BICUBIC
)
);
This code compiles fine for me.

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

This code compiles fine for me.

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

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
:

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);
