G++ compiler failed to find headers required by iostream

I'm trying to compile a simple c++ code which includes <iostream> header. Surprisingly I'm facing the error which i never faced before. Everything works fine if <iostream> header is removed.

Code:

#include <iostream>

int main(){
    return 0;
}

Compilation error:

If i remove the <iostream> header the code compiles. I think some of the headers are not found with in the include paths. But the error is very strange to me. Any help is greatly appreciated.

Solution

  • You have something unexpected in /usr/local/. Try uninstalling Microsoft® compilers, SDK, headers, etc. If you have no such packages, remove the offending files from /usr/local/include/ (or just move the whole directory into a backup).
