Compilation error with MSVC: "fatal error C1004: unexpected end-of-file found"

[fenghou]

A simple project with cmake, created by CLion (version 2022.1.3):

CMakeLists.txt

cmake_minimum_required(VERSION 3.22)
project(test20)

set(CMAKE_CXX_STANDARD 20)

include_directories(C:/Libraries/zpp_bits)

add_executable(test20 main.cpp)

main.cpp

#include <zpp_bits.h>

struct person
{
  std::string name;
  int age{};
};

int main() {
  auto [data, in, out] = zpp::bits::data_in_out();

  out(person{"Person1", 25}, person{"Person2", 35});

  person p1, p2;

  in(p1, p2);

  return 0;
}

Building output:

Looks like the problem is caused by MSCV (version 16.0), right?
How can I avoid this error?

After upgrading to Visual Studio 2022, the problem disappeared. 👏

Glad this was resolved, make sure to do not discard any error codes where this warning appears - look in the readme guide for error handling approaches.
