gnu: xkeyboard-config: Upgrade to 2.41.

[B. Wilson]

Note that the canonical location for sources has changed from
ftp.freedesktop.org to x.org. See the below discussion on the xkeyboard-config
issue tracker:

https://gitlab.freedesktop.org/xkeyboard-config/xkeyboard-config/-/issues/353#note_2431606

The old location still works, but it remains several versions behind upstream.

On my machine, the referrers of xkeyboard-config are:

libxkbcommon
setxkbmap
xkbcomp
xorg-server

What's the proper procedure when updating packages to check that its reverse
dependencies aren't broken by the change?

Beautiful! Keep me posted, and let me know if there's anything I can help with.

Help packaging ArrayFire

[B. Wilson]

Hello Guix,

Knee deep in CMake hell here and would appreciate a helping hand. ArrayFire
build is defeating me:

CMake Error at 
/gnu/store/ygab8v4ci9iklaykapq52bfsshpvi8pw-cmake-minimal-3.24.2/share/cmake-3.24/Modules/ExternalProject.cmake:3269
 (message):
  error: could not find git for fetch of af_forge-populate
Call Stack (most recent call first):
  
/gnu/store/ygab8v4ci9iklaykapq52bfsshpvi8pw-cmake-minimal-3.24.2/share/cmake-3.24/Modules/ExternalProject.cmake:4171
 (_ep_add_update_command)
  CMakeLists.txt:13 (ExternalProject_Add)

Apparently, some of the build dependencies get automatically cloned, but I'm
unable to make heads or tails of how to work around this. The
`af_forge-populate` makes it look like it's related to Forge, but "ArrayFire
also requires Forge but this is a submodule and will be checkout during
submodule initilization stage. AF_BUILD_FORGE cmake option has to be turned on
to build graphics support," so I'm stumped.

I need this soon for a project and am willing to pay someone to take this over.

Here are the official build instructions: 
https://github.com/arrayfire/arrayfire/wiki/Build-Instructions-for-Linux

In fact, there's a 2016 thread where Dennis Mungai claims to have successfully
gotten ArrayFire packaged on Guix: https://issues.guix.gnu.org/23055. However,
that appears to have never resulted in a patch.

Thoughts?

I was mostly trying to indicate the backtrace where shepherd complains about an
unknown keyword #:suplementary-groups. It looks like that's happening during or
right after /etc population.

Shepherd erroring on guix system reconfigure

[B. Wilson]

Hey Guix,

After pulling about an hour ago and attempting to reconfigure, it looks like
shepherd is falling over, even though the reconfigure command finishes:

The last I have reconfigured is about two weeks agod. Any idea what might be
going on and should I expect problems? As you can see, though, the current
generation is booting, and all looks well AFAICT:

Error pulling custom channel that includes another third-party channel

[B. Wilson]

Hey Guix,

In my channels.scm, in addition to the primary guix channel I have my-channel
and other-channel. This has worked just fine, until I added a commit in
my-channel which use-modules something from other-channel.

Now guix pull fails when attempting to build my-channel:

(exception misc-error (value #f) (value "no code for module ~S") (value 
((other channel module))) (value #f))

What am I missing?

Just to be clear, locally building with `guix build -L path/to/my-channel foo`
succeeds just fine. Is there somewhere inside my-channel where I need to
explicitly declare the dependency on other-channel?

Any help appreciated. Cheers,

BW

Re: Do we want versioned symbols in ncurses?

[B. Wilson]

Thanks for the quick turnaround.

> Debian has identifier some potential problems, quoted from

Ah, yes. The version script also sets a bunch of symbols to local scope. Good
catch.

Off the top of my head, the only sanity-check I can come up with is a brute
force one: iterate through all referrers of ncurses, and check all their ELFs
for missing symbols.

Agreed. I'm not sure it's worth the effort given the above.

For in-tree packages, there is vanishing benefit, but my particular pain
point was using a particular external pre-built .so. Oh well.

Do we want versioned symbols in ncurses?

[B. Wilson]

Hey Guix,

Is there any particular reason why our current ncurses packages builds without
versioned symbols? Upstream specifies only default versions (i.e. via @@), no
forced ones, so IIUC that should make the library drop-in replaceable for
everything we have so far. Am I missing something?

Building with symbols is easy enough: just configure --with-versioned-syms=yes.

I ran into this after encountering a project that explicitly uses ncurses
symbol versions. It is simple enough to carry a custom ncurses in my personal
channel for this, but if possible I thought it would be cool to have it in the
main one.

Thoughts?
