Problem: Compilation errors

[Da1sypetals]

From muda-app code, changing hello_muda.h to the following causes thousands of lines of compilation error.

hello_muda.h:

#pragma once
#include <muda/muda.h>

namespace md = muda;

void hello_muda();

class Cloth{
    md::HostVector<float> hx;

};

terminal output: output.txt first few lines:

I believe this is some configuration mistake but I just cannot figure it out. Thanks a lot in advance.

You should not expose any cuda-related code to a normal cpp source. So, anything about muda should not be included in a .cpp file. It May be the time to learn from https://github.com/phys-sim-book/solid-sim-tutorial-gpu, how to hide the backend implementation from the normal host cpp program.

Get it. It is just the error message is too unrelated to cuda :sob: I will learn from the repo, thanks!
