C stdio.h no such file or directory

Question

gcc worked perfectly fine until I updated to Ubuntu 16.04 and now when I run:

gcc file.c

an error shows up:

file.c:1:18: fatal error: stdio.h: No such file or directory
compilation terminated.

I checked if stdio.h was there and it still was in /usr/include/stdio.h. Please help!

Solution 1

Run:

sudo apt install --reinstall gcc-5.4

This reinstalls gcc. Reinstalling sometimes fixes problems.

Solution 2

First run:

find /usr/include/ -name "stdio.h"

If no files are returned, run:

sudo apt install --reinstall build-essential

That will reinstall any missing files.

Solution 3

Install missing library:

sudo apt install libc6-dev

sudo apt install --reinstall build-essential fixed the error for me, thanks!

I added "-get" after "apt" to be "sudo apt-get install --reinstall build-essential", so that the computer executes the command successfully. Thank you. Peace.

Hi! Thanks for your answer! Could you also please add a couple of screenshots to make it easier for users to find and apply this setting?
