Microsoft’s addition of the Bash shell and Ubuntu user space in Windows 10 is a real win for developers everywhere. Dozens of compilers and thousands of libraries are now immediately available on Windows desktops. In this article, we’re going to write the classic “hello world” application in several different compiled languages, install any necessary dependencies, and execute our compiled code.
If you’d like to follow along this article and try out these examples, you can grab all of the source code from git:
$ sudo apt update $ sudo apt install -y git $ git clone https://github.com/dustinkirkland/howdy-windows.git $ cd howdy-windows $ make
Now, let’s look at each language:
-
Installation
$ sudo apt install -y gcc
-
Code: c/howdy.c
#include <stdio.h>
int main() {
printf(” ====> C: Howdy, Windows!n”);
return 0;
}
-
Compilation
$ gcc -o c/howdy c/howdy.c
-
Execution
$ ./c/howdy
====> C: Howdy, Windows!
-
Installation
$ sudo apt install -y g++
-
Code: cpp/howdy.cpp
#include <iostream>
int main() {
std::cout << ” ====> C++: Howdy, Windows!n”;
}
-
Compilation
$ g++ -o cpp/howdy cpp/howdy.cpp
-
Execution
$ ./cpp/howdy
====> C++: Howdy, Windows!
-
Installation
$ sudo apt install -y golang
-
Code: golang/howdy.go
package main
import “fmt”
func main() {
fmt.Printf(” ====> Golang: Howdy, Windows!n”)
}
-
Compilation
$ go build -o golang/howdy golang/howdy.go
-
Execution
$ ./golang/howdy
====> Golang: Howdy, Windows!
-
Installation
$ sudo apt install -y gfortran
-
Code: fortran/howdy.f90
program howdy
print *, ” ====> Fortran: Howdy, Windows!”
end program howdy
-
Compilation
$ gfortran fortran/howdy.f90 -o fortran/howdy
-
Execution
$ ./fortran/howdy
====> Fortran: Howdy, Windows!
-
Installation
$ sudo apt install -y fp-compiler
-
Code: pascal/howdy.pas
program Howdy;
Begin
writeln(‘ ====> Pascal: Howdy, Windows!’);
end.
-
Compilation
$ pc pascal/howdy.pas
-
Execution
$ ./pascal/howdy
====> Pascal: Howdy, Windows!
-
Installation
$ sudo apt install -y erlang-base
-
Code: erlang/howdy.erl
-module(howdy).
-export([howdy/0]).
howdy() -> io:fwrite(” ====> Erlang: Howdy, Windows!n”).
-
Compilation
$ erlc erlang/howdy.erl
-
Execution
$ erl -noshell -s howdy howdy -s init stop
====> Erlang: Howdy, Windows!
