g++ does not make any file or give any output

问题

I've just started using g++, downloading the latest version from the site, and I've made a simple HelloWorld program.

#include <iostream>
using namespace std;
int main()
{
  cout << "Hello World!" << endl;
  return 0;
}

When I try to execute using the powershell window and g++, in the right directory, I use the following command:

g++ HelloWorld.cpp -o HelloWorld.exe

This gives no output and makes no files. I used the -v command as per some other answer I read on the site and it gave me this. I don't know how to proceed and execute my program.

回答1:

I've had the same issue and, after running it with the traditional batch console instead of powershell, I noticed a dll was missing. The dll error won't pop up in the powershell command line (god only knows why).

In my case it was libisl-15.dll, but it may be different on your PC.

Hope this helps someone in the world!
