Unable to compile a simple C ++ program in Ubuntu

I tried to create a simple program in the terminal.

#include <stdio.h>
#include <stdlib.h>
int main()
{
        printf("TESTING");
        return 1;
}

I performed g ++ -o test test.cpp

Errors:

/usr/include/features.h:323:26: error: bits/predefs.h: No such file or directory
/usr/include/features.h:356:25: error: sys/cdefs.h: No such file or directory

The list goes on like this. I hope someone can point out what I did not do to make this work.

SOLUTION: My path was empty due to some previous attempts to make it work. I created a clean path using:

export PATH= /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

My problem after compilation was that the program would not show any results. This was due to the fact that as a new linux user, I did not understand that I needed to call the program from the / front. You can also set this in the path by calling:

export PATH: $PATH:./

int main(int argc, char *argv[]) {
  printf("TESTING");
  return 0;

I had a very similar problem. In my case, the problem was that I had some damaged header files, as evidenced by their viewing:

/usr/include/x86_64-linux-gnu/sys$ cat *  | grep "Input/outpu error"
cat: ioctl.h: Input/output error
cat: types.h: Input/output error

The solution for me was to clean these files and then install them again.

sudo apt-get purge libc6-dev
sudo apt-get install libc6-dev
