Weird Compilation Error

I just installed the coding studio on my laptop and I am getting a weird compilation error. I tried some code that I know has worked before and it says:

10:37:37 -- error -- In file included from ../vexv5/gcc/include/_ansi.h:16: 
../vexv5/gcc/include\sys/config.h:5:10: fatal error: 'sys/features.h' file not found 
#include        /* POSIX defs */ 

I have tried to use the repair version of the installer, but the problem persists.
