Dependencies: gmp, mpfr, mpc

Dependencies: gmp, mpfr, mpc

[German Salazar]

Say, I just built gcc 10.3 and it came with instructions on how to download
and un-tar the above three dependencies within gcc own top directory; from
there, it uses them automatically without me having to install those
dependencies or specify options like "--with-gmp"

What about binutils?
Command
./configure --help
shows options "--with-gmp", " --with- mpfr", " --with-mpc"

Do I need to first install them somewhere? Permanently? Temporary?
Or
Can I just place them inside binutils source directory? Would the build
process use them from there?

What if I use the just built gcc (with gmp,mpfr,mpc) to build binutils?
Does it still need explicit access to those three dependencies?

Thanks,
Germán

the top level configure script is shared between many projects which is why
you see these options.  however, binutils does not use gmp/mpfr/mpc.  so if
you want to build binutils, ignore those flags.

gdb requires mpfr, but that's it.

gdb started using gmp a while ago as well.

Now that I think of it, I think mpfr is actually optional
(while gmp is mandatory).
