Currently on both mips64 and on armhf gst-plugins-base doesn't build, and I'm
not sure if it has any time recently. On arm, the orc related tests fail, and
on mips orc fails to build entirely. Orc is a nice addition to
gst-plugins-base, but it will build without it. This patch would have arm and
mips go without it. Currently gst-plugins-base is the only program that
directly depends on orc, so the other ~50 programs that depend on
gst-plugins-base will have a chance of building now.

Sounds good. See below for comments.

Several issues here:
* (or "armhf" "mips") always evaluates to "armhf", so this doesn't do
what you seem to be hoping for. As you have it above, orc would still
be included as an input on mips.
* When cross-compiling (%current-target-system) returns a GNU triplet
string instead of a Nix system string, and those strings start with
"arm" but not "armhf".
* If you put this ",@if" in the same place where ("orc" ,orc) is
currently located, then we can avoid rebuilding a lot of stuff on
intel architectures.
* Finally, by our indentation conventions, the consequent of the 'if'
should be lined up under the condition.
Here's one way to do it:
--8<---------------cut here---------------start------------->8---
(inputs
`(("cdparanoia" ,cdparanoia)
,@(if (any (cute string-prefix? <> (or (%current-target-system)
(%current-system)))
'("arm" "mips"))
'()
`(("orc" ,orc)))
--8<---------------cut here---------------end--------------->8---
You'll need to import (srfi srfi-1) for 'any' and (srfi srfi-26) for
'cute'.
What do you think? Can you send an updated patch?
Thank you!

One more thing: please add a comment containing the string "FIXME",
explaining that we are omitting "orc" on arm and mips, and the reason
why.
Thanks!

64-bit Arm is Aarch64 and not arm64, so this probably won't capture
64-bit Arm if/when we start to support it.

It turns out I didn't search gstreamer.scm well enough, so if this patch
looks good then I'll copy the syntax over to the other packages in
gstreamer and make patches for them too.

We shouldn't assume that the same problem will occur on Aarch64.
I'd prefer to wait and see.

To be honest, I'm having second thoughts about this entire approach.
My concern is that without orc, the codec implementations (especially
the video codecs) might be so slow as to be practically unusable. I'm
reluctant to apply this workaround too broadly until we know whether it
results in anything good. Really, we should be trying to investigate
and fix the underlying problems instead of sweeping them under the rug.
Thoughts?

Agreed. I normally try to look at supported-arch and the like while keeping
in mind that hopefully we'll have more architectures in the future.

If its unusable without orc then definately we shouldn't substitute it out.
On the other hand, `guix refresh -l orc` shows the gnome metapackage,
enlightenment, libreoffice, iceweasel, etc. Other than rhythmbox and guitarix
nothing seems like it should rely too heavily on gstreamer or on its usage of
orc's "just-in-time tools for compiling and executing simple programs that
operate on arrays of data." Giving the other programs a chance to build on
arm and mips I'm sure would be nice for their users. The best would, of
course, be to test it, but otherwise it should be okay to go without it.
