Hello,

I would like to use promises and futures in our embedded app.

We're targeting ArchLinux ARM. I believe we can build against a GCC 4.7.2
toolchain which has either C++0x or possibly even C++11 (somewhat) support.

I am trying to setup a couple of simple issues to make it even compile, but
am having trouble.

        boost::packaged_task<vector<int> >
int_vect_pt_(simple_vector_getter);
        boost::unique_future<vector<int> > int_vect_f_ =
int_vect_pt_.get_future();
        boost::thread task(boost::move(int_vect_pt_));

        boost::packaged_task<int> int_pt_(simple_getter);
        boost::unique_future<int> int_f_ = int_pt_.get_future();
        boost::thread task(boost::move(int_pt_));

Error(s):

Description    Resource    Path    Location    Type
'boost::move' is ambiguous '
Candidates are:
boost::type move(boost::packaged_task<int> &)
'    optics.cpp    /detector/devices    line 156    Semantic Error

Description    Resource    Path    Location    Type

Candidates are:
boost::type move(boost::packaged_task<std::vector<int,std::allocator<int>>>
&)
'    optics.cpp    /detector/devices    line 152    Semantic Error

Can anyone help or otherwise advise? I've even got a "crude" future
implementation in C# .NETCF for pity's sake... Anyway, if necessary, what
did we do before promises/futures? ;-)

Thank you...

Regards,

Michael Powell
