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

Had the same problem with a number of files, and was confused because the multiple definition problems usually are handled by guarding ala.

# ifndef Function_name_Guard
#define Function_name
your code
#endef % Function_name_Guard

What worked was to instead omit the .cu files, and only keep the main file.
