I've had this issue a few times, and there was something wrong with my g++ installation, I suggest you try compiling manually and see what happens.

[dpsingh11]

that must be because of wrong code which you are trying to compile .do check your code as well before compiling

[Tejasvigupta]

#include <bits/stdc++.h> using namespace std; int main(){ int n,a; cin>>n; vector v; for (int i=0; i<n;i++){ cin>>a; v.push_back(a); } for (int i=0 ;i<n ;i++){ cout<<v[i]; } } this is a simple code and it was working fine on online compiler

Hi ,I tried compiling it on an online compiler and it worked fine there.

Are you familiar with some good packages for c++ ? Please suggest some because I have been running into one or other error.

[Spodeian]

#include <bits/stdc++.h> using namespace std; int main(){ int n,a; cin>>n; vector v; for (int i=0; i<n;i++){ cin>>a; v.push_back(a); } for (int i=0 ;i<n ;i++){ cout<<v[i]; } } this is a simple code and it was working fine on online compiler

There are errors in here (and the formatting is bad).

#include <iostream>
#include <vector>

using namespace std;

int main() {
	int n, a;
	vector<int> v;

	cin >> n;

	for (int i = 0; i < n; i++) {
		cin >> a;
		v.push_back(a);
	}

	for (int i = 0; i < n; i++) {
		cout << v[i];
	}

	return 0;
}

try that

Also when I was having that error it was because of my float libraries being outdated in my g++ installation.

Also when I was having that error it was because of my float libraries being outdated in my g++ installation.

#include using namespace std; int main(){ int a=5; auto b=a; cout<<b; } I am not able to compile even this code. Should I reinstall atom or what? p.s I am new to c++.

[Double-Wen]

The same problem me too

[Spodeian]

Also when I was having that error it was because of my float libraries being outdated in my g++ installation.

#include using namespace std; int main(){ int a=5; auto b=a; cout<<b; } I am not able to compile even this code. Should I reinstall atom or what? p.s I am new to c++.

#include <iostream>
using namespace std;
int main(){
int a=5;
auto b=a;
cout<<b;
}

#include needs to actually have something to include, it can't be left empty, on top of that, cout doesn't work without iostream.

If you can't compile with this plugin on Atom, try to do it just using MSYS and g++.

The smallest code that would compile (that I can think of and has at least 1 non-return statement) is:

int main() {
  a = 0;
  return a;
}

However, my windows defender thought it was a virus. You could also do:

#define A 0
int main() {
  return A;
}

Today, I found a way to fix that #319

[AleML24]

Can someone explain to me why when I compile a code I get this error: The error was thrown from the gpp-compiler package. What does that mean ? What I do?
