GMP error

Hello, I have installed gmp library on a centos system. The problem is while compiling only mpz_inits and mpz_clears are giving errors, all the other functions compile fine.
The errors given are:
undefined reference to `__gmpz_inits'
undefined reference to `__gmpz_clears'

If I used multiple mpz_init and mpz_clear, the program compiles without any error and gives the appropriate output.
Why is this happening? Please help.
