The Mer project OBS[0] uses qemu ARM emulation and the speed seems to
be fine. Also I think the production builds for Sailfish OS are done
the same way.

There's a bunch of issues with cross compiling a lot of things,
partially around a bunch of the things that run around the actual
composing. The way OBS does that is by running those bits in a qemu
emulated. It's quite messy and it would need a bunch of development.
We're much closer to getting ARMv7 on aarch64 VMs running and that
would be more suitable for all involved.

There are plans, it's just not been implemented yet. ;) 

We have some hardware in place, we just need to it integrated with
copr. Hopefully before too long.

The attempts at emulated builds have usually been slower than the hardware
builds

​Why don't we do emulated builds (like how OBS does it for ARM)?​

COPR for ARM?

[Jerry Vonau]

Hi All,

I really like being able to use COPR to build rpms, what a great tool. Be
nice to have a one stop shop under one roof for all the supported arches.
Given that 'armhfp' is now a primary arch are there any plans in the works
to offer 'armhfp' chroots in COPR? 

Thanks in advance, 

JerryV

​Are they unusable? I find it hard to believe that ​emulated builds are
that horrible for building in when we don't have much hardware for ARM
builds...

If we are talking about cross-compiling emultation builds (some people
use that term so I need to make sure I am clear) then I think we
haven't looked into it because we don't do cross-compiles in the main
build system. If we are talking about using qemu to emulate arm, the
problem is that the speed was so slow that it was interfering with
builds thinking they were broken (timed out) when they were just
really slow. However that was a long time ago (2 years?) so it may
have improved.
