Cuda error: function has already been defined in another .cu.obj file

Question

I am trying to compile a cuda project that someone sent me. Though the compile stage passes, the link stage is failing. Below is an example of the error:

Err         


        

Answer 1

This is just a guess, but if this is visual studio, I've seen this case before when the code is in a .cu file that is #included. In that case it should not also be compiled as a source file. To avoid this, right click on one of the files (hard to tell which from your description) and select properties, and then find and check the "exclude from build" check box.
