Getting error: “nvlink error : Undefined reference to '_ZN8Strategy8backtestEPffffd'”

Question

I am getting the following error when running make for my CUDA (v7.5) application:

nvlink error : Undefined reference to \'_ZN8Strategy8backtestEPdd         


        

Answer 1

Turns out objects passed to CUDA kernels cannot have virtual functions. See this thread.

However, it seems that objects instantiated and used only within the kernel can have virtual functions.
