thrust::reduce example code from sum.cu (and thrust homepage) generates linker errors

[GoogleCodeExporter]

Please post a short code sample which reproduces the problem:

#include <thrust/host_vector.h>
#include <thrust/device_vector.h>
#include <thrust/generate.h>
#include <thrust/reduce.h>
#include <thrust/functional.h>
#include <cstdlib>

void main()
{
    // generate random data on the host
    thrust::host_vector<int> h_vec(100);
    thrust::generate(h_vec.begin(), h_vec.end(), rand);

    // transfer to device and compute sum
    thrust::device_vector<int> d_vec = h_vec;
    int x = thrust::reduce(d_vec.begin(), d_vec.end(), 0, thrust::plus<int>());
}

What is the expected output? What do you see instead?

It's worth noting that the following linker errors go away when the the call to 
thrust::reduce is commented out.

What version of Thrust are you using? Which version of nvcc?  Which host
compiler?  On what operating system?

Thrust 1.3, NVCC 3.2 64-bit, MSVC 10, Windows 7 64-bit

Please provide any additional information below.

Are there any quick hack workarounds for this?   :)

Oops. In Visual Studio I have "Platform Toolset" for this project set to vc90, 
so the compiler that compiles this thrust code is MSCV 9.

Cheers,
Mike

Thanks for the report, Mike.

I'm not able to reproduce this problem on my system (Thrust 1.3.0, nvcc 3.2 
32b, MSVC 9 32b).  Can you attach the output of nvcc --verbose?

Hey Jared,

You can safely file this bug under "Mike's an idiot". I was compiling outside 
of NVCC. 

The thrust interface is so high-level and pleasant it started sneaking into my 
cpp files. I moved the reduce code into a .cu file, compiled with NVCC, and the 
problem went away.

Thanks so much for your help.  :)

Thanks for root causing it, Mike.

Actually this is our fault; compiling in CUDA mode without nvcc should produce 
a compiler error, not a confusing linker error.  I've filed a separate issue to 
track this problem [1].
