Note: I know that questions with this error already exist. However, I believe that this question is not a duplicate of any of the questions I have already seen, as it's... pretty weird.
I was just using Geany 1.37 to build a blank program:
#include <iostream>
#include <fstream>
#include <cmath>
#include <algorithm>
#include <vector>
using namespace std;
// This line is referred to as "line 8" below
int main()
{
return 0;
}
The above program, when I hit the "Build" button, compiled normally. However, I then typed using namespace abc = std; on line 8, and tried building again. When I hit the "Build" button at the top of the interface, however, I suddenly got the error message
make: *** No targets specified and no makefile found. Stop.
(I know that using namespace abc = std would have caused a compilation error; I was curious as to what the compilation error would say exactly).
Now, I seem unable to build my program at all. My build commands have not changed at all, so I've come to the conclusion that I might've accidentally hit a weird keyboard shortcut that triggered this problem while typing using namespace abc;. Can somebody please tell me if a keyboard shortcut has been known to cause this issue, and what that keyboard shortcut would be?
