Undefined symbols for architecture arm64:.... #6

Hello,

First, thanks for the great code. It is very helpful to have something nice to visualize the c++ results.

I have go through the code and it seems I am compiling it correctly. However, I am having the following error after the compilation:

"Undefined symbols for architecture arm64:

ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)"

I wonder if there is a solution for this. I am running in an M1 MacBook Pro.

Thanks in advance.
