[Message part 1 (text/plain, inline)]

Hi,

We have been using the attached devel-hurd.tmpl (see attched) to add a
childhurd service that has a development environment.

On current master

    395489cdc959c3f3c026bf545c3ed95efc9919f0
    gnu: spice-vdagent: Update to 0.20.0.

building

    ./pre-inst-env guix system disk-image --target=i586-pc-gnu gnu/system/examples/devel-hurd.tmpl

fail with

--8<---------------cut here---------------start------------->8---
guix system: error: gnu/packages/glib.scm:181:2: glib <at> 2.62.6: build system `meson' does not support cross builds
--8<---------------cut here---------------end--------------->8---

I guess we are missing a (some?) tests for the Hurd.

Anyway, I started a bisecting round last night and it found

--8<---------------cut here---------------start------------->8---
1b0cda6b44 gnu: qemu: Extend I/O test time-outs.
--8<---------------cut here---------------end--------------->8---

which was an honest debugging leftover, fixed promptly in

--8<---------------cut here---------------start------------->8---
b070e3f810 gnu: qemu: Remove left-over debugging statement.
--8<---------------cut here---------------end--------------->8---

Luckily, this fixed commit also builds the childhurd again...so I'm
starting a new bisect.

This is not funny; it means I either cannot reconfigure, or I'm losing
my childhurd...grmbl.  Sorry for not noticing this earlier!

Greetings,
Janneke

My bad, turns out to be the new guile-avahi dependency that cannot be
cross-built.

For the archives, find an updated devel-hurd.tmpl attached that removes
guile-avahi.

Good catch, thanks for the fix!

Hi Ludo,

that is not a fix.  A workaround maybe.

If possible, I'd like the actual fix to be to make the meson build system
support cross compilation.

According to https://mesonbuild.com/Cross-compilation.html :

>Meson has full support for cross compilation. 
[...]
>meson builddir/ --cross-file x86-linux

Also, for the record, I find it a bad idea to switch packages from
gnu-build-system to meson-build-system when the package in question
supports building itself with either, as long as meson-build-system
doesn't support cross-compilation.
