LinuxQuestions.org - Can't Compile GMP with gcc mac 10.4.11

Ok I realize this is a Linux forum, but can I at least be pointed to a more relevant forum.

My problem is when I try to compile a program with GMP gcc doesn't compile but gives the error:

/usr/libexec/gcc/i686-apple-darwin8/4.0.1/ld: Undefined symbols:
___gmpz_get_d
___gmpz_init
___gmpz_mul_ui
___gmpz_set_ui
collect2: ld returned 1 exit status

I'm compiling from terminal using the command

gcc clarkkkkson.c -o clarkkkkson

and I have tried the options

-lgmp
-lgmp -L/usr/local/include
-lgmp -L/usr/local/lib
-lgmp -L/usr/local/lib/
-lgmp -L/usr/local/lib/libgmp.dylib
-lgmp -L/usr/local/lib/libgmp.a
-lgmp -L/usr/local/lib/libgmp.la
-L/usr/local/lib/libgmp.dylib
-L/usr/local/lib/libgmp.la
-L/usr/local/lib/libgmp.a
-L/usr/local/lib/

to no avail. The source code is

Code:

double fact(unsigned int number, unsigned int class_) {

        mpz_t return_;

        mpz_init(return_);

        mpz_set_ui(return_,1);

        unsigned int i;

        if(class_-1) for(i=1;i<=number;i++) mpz_mul_ui(return_,return_,fact(i, class_-1));

        else for(i=1;i<=number;i++) mpz_mul_ui(return_,return_,i);

        return mpz_get_d(return_);

        mpz_clear(return_);

}

I have compiled GMP myself and did run make check after make and make install. And I did try recompiling.
