Thomas, All,
On 2018-02-05 22:10 +0100, Thomas Petazzoni spake thusly:

>
> gdb 8.1 has a new optional dependency on mpfr, which according to the
> NEWS file:
>
> GDB now uses the GNU MPFR library, if available, to emulate target
> floating-point arithmetic during expression evaluation when the
> target uses different floating-point formats than the host. At
> least version 3.1 of GNU MPFR is required.
>
> So for the target gdb, this is unnecessary, and therefore we
> forcefully disable mpfr support by passing --without-mpfr.
>
> For the host gdb, it would potentially be useful, but since it's a new
> feature that isn't essential, we for now keep it disabled as well. An
> option may be added later if needed.
Agreed.

And there you would have added:
select BR2_PACKAGE_GDB_NEEDS_CXX11
Otherwise;
