Re: compiling for other architecture [armv6 targeting specifically]

Hey Mark,

Thanks for that information. I messed up the target architecture. I was
trying to build for 64 bit arm, anyways (just a typo). I've tried poudriere
with qemu-user-static but there are a lot of errors, indeed. Only a few
packages build just fine.

Since I am fairly new to FreeBSD I was under the impression that it would
support aarch64 as a platform. I guess it does, but this does not include
the ports collection.

No problem. Since I was targeting the Pi as a device for a few simple
things I might be able to build what I need without using the ports
collection.

Are there any plans (or a working group) trying to improve the situation of
the ports collection for other platforms? Doing real native cross-compiling
and slowly working things out that outright fail even under emulation?
