The version of simple-scan that current in Guix, 3.24.1, which fails to

build is a little old. I tried to update it to the version that

numerically matches our GNOME version, 3.30.2, but that fails with the

same problem.

However, the current newest simple-scan release, 3.34.1, does build.

Unfortunately, I had to take the colord out of inputs or native inputs

otherwise the build would fail with

"error: Package `colord' not found in specified Vala API directories or

GObject-Introspection GIR directories"

and I didn't see how it was detecting colord during configure, but not

during the build. The needs to be fixed eventually, but in the meantime I

have prepared the following patch.

A bigger problem than colord though, is that while simple-scan now builds,

it doesn't run. It exits after printing "Trace/breakpoint trap". I've

attached strace output.

I'm not sure what's next, thoughts?

Best,

Jack

[build-system]: Switch to meson-build-system.

[source]: Fetch from GNOME mirrors.

[inputs]: Add libwebp.

[native-inputs]: Remove colord.

[arguments]: Remove #:configure-flags. Remove 'clean phase.

[home-page]: Update to current home-page.

I was also quickly trying out the same things you did and came to the

the meson-build-system and have no futher idea.

Oh, sounds bad. I haven't tried to run it.

No.
