I am trying to compile the main.c file in Linux environment there are three header files included in main.c
#include <stdio.h>
#include <assert.h>
#include "ftd2xx.h"
getting the errors…

Your command to built the application lacks the option to link the library.
Try this:
gcc main.c -lftd2xx
Please be aware that the resulting binary has the default name of a.out, which might not be what you want.
I suggest to learn a bit more about general usage of compilers, linkers, and GCC as your actual compiler.
