paiza.ioでnode.js その5

Posted at

概要

paiza.ioでnode.js、やってみた。
練習問題やってみた。

練習問題

gccでコンパイルせよ。

サンプルコード

process.stdin.resume();
process.stdin.setEncoding('utf8');

const fs = require('fs');
const { exec } = require('child_process');

fs.writeFileSync("main.c", "#include<stdio.h>\nint main() { puts(\"Hello world\"); }");

exec('cat main.c', (err, stdout, stderr) => {
	if (err) 
	{
		console.log(`stderr: ${stderr}`)
		return
	}
	console.log(`stdout: ${stdout}`)
})

exec(`gcc main.c`, (compileError) => {
	if (compileError) 
	{
		console.error(`コンパイルエラー: ${compileError}`);
	}
	console.log('Cプログラムのコンパイル成功');
});



実行結果

コンパイルエラー: Error: Command failed: gcc main.c
/bin/sh: 1: gcc: not found

成果物

以上。
