I tried to build the "minimal" buildset for the IMXRT BSP and I get undefined INET6 references -
_bsd_inet6_pfil_hook, _bsd_ip6stat, etc. Only two executables are created - swi01.exe and timeout01.exe.
For "default" (almost) everything builds except for a few that won't fit in RAM but I don't
currently have enough RAM to run anything so I figured my first step should be to build "minimal".
I just tried it with beagle bone black: The minimal buildset builds fine. Can
you tell from the output who is referencing the inet6_pfil_hook and ip6stat?
Let's look at inet6_pfil_hook. It's only called in "if_bridge.c" by
bridge_pfil, bridge_fragment, bridge_dummynet, bridge_broadcast, bridge_ioctl,
bridge_ioctl_add, bridge_forward, and bridge_input.
Yes, right. But if I didn't miss one, they should be all called only if
INET6 is defined (in rtemsbsd/include/rtems/bsd/local/opt_inet6.h). In
the minimal buildset that shouldn't be the case.
Do you have a previously installed libbsd in your prefix that might mess
with the build?
These are all statics. Is there something going on with inlining and "garbage
collecting"? Do I have C flags messed up? I'm not sure how this is works as I see that
"_bsd_inet6_pfil_hook" is defined in ip6_input.c and the object is in the built libbsd.a.
I see there's some -Bstatic and -Bdynamic stuff going on in the link.
The ip6_input shouldn't even be in the minimal buildset. Minimal doesn't
have IPv6 support.

Start of the link of netshell01. I can send more info if you'd like, I don't
want to swamp the list.

The configure command is:

Looks OK.
The libbsd is a recent 6-freebsd=12
is "minimal" built regularly? Any hints?
No it is not build regularly. I think the buildset are often forgotten if someone works
on libbsd. For example "everything" doesn't build at the moment.
