I've already succeeded at building gmp, and mpc with in the gcc build
directory, I need to make mpfr, what do you suggest I do?
Is there a way to just build the following code block;
1. | int
2. | main ()
3. | {
4. | mpfr_t x; mpfr_init(x) ; mpfr_clear(x);
5. |
6. | ;
7. | return 0;
8. | }
and then re-run make?
