[Solved] No rule target Libxfce4util.typelib and Libxfce4ui.typelib

Hi All,

I'm trying to build from source, and in both the 'libxfce4util' and 'libxfce4ui' libraries I get the following make errors:

make[3]: *** No rule to make target 'Libxfce4util-1.0.typelib', needed by 'all-am'.  Stop.

Same for Libxfce4ui ...

make[3]: *** No rule to make target 'Libxfce4ui-2.0.typelib', needed by 'all-am'.  Stop.

Web searches have been unhelpful. Forum search did not appear to find anything.

Knowledge gap in pulling apart the generated makefiles, so I don't know if I'm missing something obvious.

uname -a output

Linux valhalla 6.13.8-arch1-1 #1 SMP PREEMPT_DYNAMIC Sun, 23 Mar 2025 17:17:30 +0000 x86_64 GNU/Linux

If this is the wrong area for it, can someone please point me in the right direction.

Re: [Solved] No rule target Libxfce4util.typelib and Libxfce4ui.typelib

Hello and welcome.

Which distro and versions of libxfce4util and libxfce4ui are you trying to build?

Can you also post the full configure/autogen.sh commands you are using as well as the full configure and build (make) outputs?

Have you first built xfce4-dev-tools?

Re: [Solved] No rule target Libxfce4util.typelib and Libxfce4ui.typelib

Arch (updated before git pulls). Arch is behind a version on libxfce4ui it seems.

Latest git pulls for libxfce4util and libxfce4ui (at time of initial post), plus xfce4-settings (the goal to rebuild this ultimately).

xfce4-dev-tools is installed. I pulled it from git and did a build off that too, in-case that was an issue; though same error with UTIL and UI libs after building. Although, now I'm wondering if I should purge the package, and rebuild it.

Configure via autogen.sh script.

Actually, I think the line of thought about everything being the same release version solved it.

I downloaded the matching version of xfce4-settings on Arch currently: 4.20.1 via https://archive.xfce.org/src/xfce/xfce4-settings/4.20/

And that built and installed with no issues.

Which I've just noticed you commented on too (very active )

Happy to mark solved. Thanks.
