c - can't compile with ubuntu

I have 64bit ubuntu installed, and I am trying to compile a code with times.h however I keep getting sys/times.h No such file or directory

What I have tried so far
1. installing libc6-dev-i386, g++-multili, and libc6 and libc6-dev (Even though it is already installed)
2. I swapped <sys/times.h> to </usr/include/sys/times.h> and now I am getting features.h No such file or directory error

Question:
It is weird how it accepts </usr/include/sys/times.h> instead of <sys/times.h>, and help?

EDIT: I can access times.h, if it matters
