You need to have a header file that declares doStuff() and include the header not the definition.</p> <p>The following might be helpful. </p> <p><a href="http://www.ademiller.com/blogs/tech/2010/12/using-cudathrust-with-the-parallel-patterns-library/" rel="nofollow">http://www.ademiller.com/blogs/tech/2010/12/using-cudathrust-with-the-parallel-patterns-library/</a></p> <p><a href="http://blog.cuvilib.com/2011/02/24/how-to-run-cuda-in-visual-studio-2010/" rel="nofollow">http://blog.cuvilib.com/2011/02/24/how-to-run-cuda-in-visual-studio-2010/</a></p> <p>Typically I set this up as two projects. One project that compiles against the the 2008 CPP compiler for .CU and another that uses the 2010 compiler to get all the C++0x features.</p> <p>The warnings your getting can be fixed by exporting the appropriate templates.
