nvcc throws
/usr/include/boost/concept/detail/has_constraints.hpp:29: error: ‘&’ cannot appear in a constant-expression
/usr/include/boost/concept/detail/has_constraints.hpp:29: error: template argument 2 is invalid
the has_constraints.hpp already has some suspicious code in it:
#if BOOST_WORKAROUND(__SUNPRO_CC, <= 0x580)
// Work around the following bogus error in Sun Studio 11, by
// turning off the has_constraints function entirely:
// Error: complex expression not allowed in dependent template
// argument expression
inline no has_constraints_(...);
#else
template <class Model>
inline yes has_constraints_(Model*, wrap_constraints<Model,&Model::constraints>* = 0);
inline no has_constraints_(...);
#endif
Question: Is this a nvcc - boost incompatibility, or could there be something wrong with my code?

What we did at the end was to turn has_constraints_ off as in the example quoted in the question for Sun Studio 11

I have a patch here http://code.google.com/p/asadchev/source/browse/trunk/projects/boost/boost-1.46.0.nvcc.patch
Perhaps you can see what is changed and fix your code likewise
Be aware that the source is seen by both, gcc-like and egg-like compiler parts.

Why do you have the "&" before "Model::constraints"? I would think that's the problem. (// it's not apparently)
EDIT:
http://forums.nvidia.com/index.php?showtopic=182890 talk about this issue and have some hack work arounds

EDIT2:
Well, after running around this for a while, this is what I'm sticking with:
http://forums.nvidia.com/index.php?showtopic=215470 "There is a known compatibility issue with boost and nvcc. A work around is to split the sources such that you compile the cuda code with nvcc and the boost code with the host compiler." by Justin Luitjens in the Group: NVIDIA Employees
Try it out, but if you can't make it work, compile separately, and then link them.
