Re: mpfr.h cannot be located while compiling GCC

I added GMP & MPFR folders into GCC source code folder .......

configured GCC ... into different directory named objdir which is
outside gcc source code folder.

Now I am doing make .... but it gives the following error:

.
.
.

      _mpfr_tan$non_lazy_ptr in libbackend.a(builtins.o)
  "_mpfr_sin", referenced from:
      _mpfr_sin$non_lazy_ptr in libbackend.a(builtins.o)
ld: symbol(s) not found
