Cross-compilation of the helloworld program [closed]

Task: launch "Helloworld" program on Windows

Instruments: Linux mint, VScode, C++, Clang

Clang is cross-platform by definition. There was an attempt to install mingw however VSCode returned an error

fatal error: 'iostream' file not found

after command

clang++ --target=x86_64-pc-windows-gnu --sysroot=/usr/x86_64-w64-mingw32/ hello.cpp -o hello.exe

Further analysis revealed no C++ related libraries the folder.

Command:

sudo apt install mingw-w64

...simply refuses to install. What am I doing wrong, and what other solutions are there?

p.s. I dont want to change the instruments. simply because. help
