rust 와 main.rs

러스트니까 확장자가 rs인가..

함수는 fn 키워드로 구분하는 듯.

C:\Users\user\Desktop\study\rust>type main.rs fn main() {     println!("Hello, world!"); }

 

처음해보려는데 머가 잘 못 깔린걸까.. -_-

C:\Users\user\Desktop\study\rust>rustc main.rs error: linker `link.exe` not found   |   = note: program not found note: the msvc targets depend on the msvc linker but `link.exe` was not found note: please ensure that Visual Studio 2017 or later, or Build Tools for Visual Studio were installed with the Visual C++ option. note: VS Code is a different product, and is not sufficient. error: aborting due to previous error

 

먼가 열심히 object 파일은 생성하는데 linker가 없어서 실행파일을 만드는건 실패한 듯.

msvc 설치하고 나서 rustc 해서 빌드하니 아래와 같이 익숙한(!) pdb와 exe가 나온다.
