G ++ does not link header files correctly
I am using cygwin libraries to run C and C ++ programs on Windows.
gcc
works fine, but since g++
I am getting a long list of errors. I think these erros are related to linking problems with C libraries.
Can you suggest what I need to do to fix this?
initial error lines:

all errors fail: PasteBin
for people requesting the source code: this is obviously a file header issue related to the issue and happens before compilation starts. I am getting the same error for every .cpp file.
#include<cstdio>
#include<cstdlib>
#include<iostream>
#include<vector>
#include<queue>
using namespace std;
int main(){
cout<<"hello world!";
}
gives me the same error.

Key error:

The fact that g ++ is complaining that it cannot find <stdio.h>
(although it leaves the angle brackets from the post) means that you have some sort of compiler configuration problem. You may be missing an important package. I would look to reinstall or update the GCC environment to <stdio.h>
find it found.
The rest of the problems are consequences of the missing header - the compiler fights without all the information it needs to avoid generating unnecessary errors.
