rint() is a standard math library function. If you are on a Linux system, then you need to include a "-lm" at the end of the compile command.

Also, it is unlikely that you are using any of the f2c, coxplot, volpack, or mrix functions, so you can remove those libraries from the compile command. It doesn't hurt to keep them, but it is "unclean" to scan libraries you know you don't need.
