[SOLVED] CMake with msys64-ucrt64-g++ compiler does not build file with iostream functions calls

CMake with msys64-ucrt64-g++ compiler does not build file with iostream functions calls

So I was following this tutorial on CMake in VSCode setup, and everything was going good, until I tried to build project. I chose preset for urct64/bin/g++.exe. The build process exits with error and prints:

[driver] Build completed: 00:00:01.153
[build] Build finished with exit code 2

The .cpp file I am trying to run is:

#include <iostream>
// #include <stdio.h>
#include <vector>
#include <string>

using namespace std;

int main(){
    // printf("Hello world\n");
    cout << "Hello world\n" << endl;
    return 0;
}

When using stdio.h and printf instead of iostream and cout, it builds and works just fine.

Also, when changing the configuration preset from urct64/bin/g++ to mingw64/bin/g++ it builds with no problems, but .exe quits immideatly after start - it seems like it breaks on first iostream function call, because if both printf and cout are uncommented, printf works, but not cout. If these rearranged so cout is called first, both do not work.

CMakeLists is identical to one used in the tutorial:

cmake_minimum_required(VERSION 3.5.0)
project(cmake_learn VERSION 0.1.0 LANGUAGES C CXX)

include(CTest)
enable_testing()

add_executable(cmake_learn main.cpp)

set_property(TARGET cmake_learn PROPERTY CXX_STANDARD 17)

Solution

Looks like there was indeed dll compatability problem due to my unorganized MSYS packages dowloads. I reinstalled MSYS and all packeges I needed and now it works.
