Hi Andy,
I am working on better integrating targetcli in Buildroot. Buildroot
is an easy to configure build system that uses cross compilation to
generate tiny root file systems for embedded platforms.
Buildroot supports systemd so I built a root file system with
targetcli and systemd. When systemd is selected as the init system in
Buildroot, the python-kmod module is also built by Buildroot (because
kmod is a dependency of systemd). And since python-kmod is present,
targetcli tries to use it. But it fails with the following error:
# targetcli
Traceback (most recent call last):
File "/usr/bin/targetcli", line 100, in <module>

Trying to use python-kmod by hand also fails on the system.

Maybe python-kmod is not properly built. Do you have some advises of
what I should look at to debug this issue.
Can you supply the kmod/python-kmod version information?
This is the latest version of kmod:
# kmod --version
kmod version 18
(CCing kmod dev list too)
Starting in kmod v17 the Python library was merged into the main kmod
repo, and the version indicates that you are using the Python wrapper
built from that (as opposed to the now-defunct separate project called
python-kmod, whose versions never exceeded 0.9.)
Lucas De Marchi did the build integration because my autotools knowledge
was not sufficient -- I suspect building kmod with --enable-python only
enables Python 2. I'd need to know more about what distro you're on and
look at the packaging scripts, but I think upstream support for building
the library for Python 3 is needed (this might be extremely simple but
it still probably requires a separate --enable-python3 configure
option). Did the packager think they could just take the Py2 binaries
and they'd work for Python 3???
So I'd open an issue with the kmod packager for whatever distro because
something is broken, and maybe the CC'd upstream developers might also
be able to help us have explicit support for building for Python 3?
Thanks -- Regards -- Andy
