Martin, All,

On 2021-09-13 16:26 +0200, Martin Elshuber spake thusly:
> The AKA backend for 3GPP2 requires libgmp (see
> https://wiki.strongswan.org/projects/strongswan/wiki/Autoconf). Since
> the AKA backend for 3GPP2 is included by BR2_PACKAGE_STRONGSWAN_EAP,
> when selecting a crypto backend different from
> BR2_PACKAGE_STRONGSWAN_GMP, there is no guarantee the gmp package is
> selected as well. When doing so, make fails since the package is in the
> dependency chain but not selected:

>   $ make
>   Makefile:585: *** gmp is in the dependency chain of strongswan that has added it to its _DEPENDENCIES variable without selecting it or depending on it from Config.in.  Stop.
>   make: *** [Makefile:23: _all] Error 2

> To fix this, select BR2_PACKAGE_GMP when selecting BR2_PACKAGE_STRONGSWAN_EAP.

Applied to master, thanks.

I was a bit confused as to what would happen if both gmp and other
crypto backend were used to gether, but there are explicitl options to
select each of them at ./configure time, so it seems it should be OK, I
guess...
