Clang Error "stddef.h file not found"?

Question

After upgrading to Saucy, Clang now gives me the error message:

clang -Wall -Werror -std=c99 -ggdb -O0 5.1.c -o 5.1
In file included from 5.1.c:1:
/usr/include/stdio.h:33:11: fatal error: 'stddef.h' file not found
# include <stddef.h>
          ^
1 error generated.
make: *** [5.1] Error 1

BTW the header I included was stdio.h not stddef.h but I am assuming that stdio.h references or #includes stddef.h

Solution

You are missing header files. Their are 2 notable links related to this: launchpad notice and debian bug. You can fix this by removing clang and install the 3.3 version with

sudo apt-get remove clang
sudo apt-get install clang-3.3
