Bug 918387

I can reproduce it but I cannot debug it.

Even "hp-toolbox -ldebug" and also "journalctl -r"
and even also "hp-check -t" do not show
any bit more information except the poor
"warning: CUPSEXT could not be loaded. Please check HPLIP installation."

I cannot debug issues in HPLIP without more useful information.

We (i.e. openSUSE) distribute HP's HPLIP software
but we do not develop it.

In case of issues with HPLIP please report them directly to HP via
http://hplipopensource.com/hplip-web/support.html

Preferably post an URL to your upstream issue report here
as reference.

Many thanks for your upstream bug report!

Created attachment 623829 [details]
Email from Sanjay Kumar

Attached instructions received from Sanjay Kumar. Did manual installation as advised. Main change was that the installation loaded cups from ~/Printing repo. All other dependencies satisfied by exising installed software.

I can confirm that with CUPS 1.7.5 RPMs installed
the HPLIP 3.15.2 packages from
http://download.opensuse.org/repositories/Printing/openSUSE_13.2/x86_64/
work on openSUSE 13.2

This proves that the issue is indeed not in our RPMs but in HPLIP.

Basically it seems HPLIP 3.15.2 does no longer work with CUPS 1.5.4.

This should be no real issue for the next openSUSE version
because the next openSUSE version will have CUPS 2.x, cf.
http://lists.opensuse.org/opensuse-factory/2015-02/msg00122.html

And for users who use HPLIP from the openSUSE build service
development project "Printing" the newest CUPS is also
provided there.

What is missing in our newest HPLIP RPMs is a RPM requirement
for the right minimal CUPS version, cf.

Tomas Chvatal,

I think there is a typo in your hplip.chnges entry
"- Version bump to 3.15.1:"

----------------------------------------------------------------------

I think it should read:

Yep, fixed.

Only optionally FYI regarding
"Add minimal version requirement on cups (currently 1.7)"
and
"Kill sle11 support as per min cups requirement"
see
https://bugs.launchpad.net/hplip/+bug/1423220

I think with a suse_version dependant BuildRequires
it should be possible to keep SLE11 support
and support for for all released openSUSE versions.

Up to openSUSE 13.2 we officially provide CUPS 1.5.4
so that a minimal version requirement for CUPS 1.7
means to drop support for all released openSUSE versions.

Just to clarify one possible misunderstanding, I always have the ~/Printing repo in my list of repos. So I received the upgrade to hplip 3.15.2 as a result of this, not of any conscious decision to upgrade to 3.15.2.

The question is: why did I not receive the cups upgrade as well as I am permanently subscribed to this repo?

*** Bug 918828 has been marked as a duplicate of this bug. ***

Only an addendum FYI regarding
"why did I not receive the cups upgrade":

I don't know.

On my openSUSE 13.2 system it seems to work
(long lines are shown wrapped here):
----------------------------------------------------------------------------
# zypper ar
 http://download.opensuse.org/repositories/Printing/openSUSE_13.2/ Printing

# zypper -v update -r Printing -D --details
...
The following ... packages are going to be upgraded:
...
cups      1.5.4-165.1 -> 2.0.2-169.1 x86_64 Printing
 obs://build.opensuse.org/Printing
cups-client 1.5.4-165.1 -> 2.0.2-169.1 x86_64 Printing
 obs://build.opensuse.org/Printing
cups-libs 1.5.4-165.1 -> 2.0.2-169.1 x86_64 Printing
 obs://build.opensuse.org/Printing
----------------------------------------------------------------------------

I cannot answer questions regarding repositories, zypper,
or whatever else belongs to such things.

Via OBS submitrequest 288078 I tried to make HPLIP again build
correctly for released openSUSE versions and for SLE11.

The basic idea behind is to ensure also
in the Printing project what I wrote in
https://bugs.launchpad.net/hplip/+bug/1423220/comments/7
(excerpt)
--------------------------------------------------------------
ensures that the packages are built with the
CUPS version that is also provided in openSUSE.
--------------------------------------------------------------

The basic change in hplip.spec is
--------------------------------------------------------------------------
# HPLIP's Python module cupsext.so has a build-time
# dependancy on the CUPS version:
# It needs symbols (like ippFirstAttribute, ippNextAttribute,
# ippSetOperation etc)
# that are defined only in libcups.so version > 1.5.
# For backward compatibility
# cupsext.c has a macro (CUPS_VERSION_1_6) which defines
# those undefined function names
# if CUPS version is <= 1.5. To check the CUPS version
# the CUPS_VERSION_MAJOR, CUPS_VERSION_MINOR
# macros from cups/cups.h are used which means it depends
# on the CUPS version during build-time
# whether or not cupsext will work with CUPS <= 1.5 at run-time.
# See https://bugs.launchpad.net/hplip/+bug/1423220
# and https://bugzilla.opensuse.org/show_bug.cgi?id=918387
# Therefore it BuildRequires the CUPS version as provided
# in the openSUSE/SLE versions.
# Up to openSUSE 13.2 and SLE11 CUPS < 1.6 is provided
# (from CUPS 1.3.9 for SLE11 up to CUPS 1.5.4 for openSUSE 13.2).
# For SLE12 by default CUPS 1.7.5 is provided and alternatively
# CUPS 1.5.4 is provided in the "legacy" module.
# After openSUSE 13.2 (i.e. for current openSUSE Factory)
# CUPS 2.0 is provided.
# Up to openSUSE 13.2 and SLE12 it BuildRequires CUPS < 1.6
# to ensure it even works on SLE12 with CUPS 1.5.4.
# When it was built with CUPS > 1.5 it must also require
# CUPS > 1.5 during run-time.
# In contrast when it was built with CUPS < 1.6 there
# must not be a run-time requirement
# for a CUPS version to ensure it works on SLE12 both
# with CUPS 1.7.5 and CUPS 1.5.4.
# For suse_version values see
# https://en.opensuse.org/openSUSE:Build_Service_cross_distribution_howto
%if 0%{?suse_version} > 1320
BuildRequires:  cups > 1.5
BuildRequires:  cups-devel > 1.5
Requires:       cups > 1.5
%else
BuildRequires:  cups < 1.6
BuildRequires:  cups-devel < 1.6

%endif
--------------------------------------------------------------------------

FYI regarding
"build correctly for released openSUSE versions and for SLE":

I enhanced and updated the description of the OBS "Printing" project
in particular I added (excerpt)
-----------------------------------------------------------------------
The main intent of the "Printing" project is to
provide the newest kind of base-printing software
for the newest openSUSE and Suse Linux Enterprise
versions and at the same time with same priority
to provide the same newest base-printing software
also for as many older/released openSUSE and
Suse Linux Enterprise versions as possible with
reasonable effort.
.
.
.
In the end all software in the "Printing" project
are only applications.
Your system shouldn't explode when you upgrade
with packages from the "Printing" project.
If a newer version does not work it should usually
help to downgrade to get it working again.
If there are issues with the packages in the
"Printing" project we appreciate issue reports.
In this case see "How to Report a Printing Issue" at
https://en.opensuse.org/SDB:How_to_Report_a_Printing_Issue
-----------------------------------------------------------------------

Only FYI:

I verified that now HPLIP is built in "Printing"
with the CUPS version that is by default available
in the particular openSUSE and SLE version:

I also verified that for HPLIP 1.15.2 from "Printing"
on my openSUSE 13.2 system with its default CUPS 1.5.4
"python import cupsext" works:
----------------------------------------------------------------------------
# rpm -qi cups | grep '^Ve'

# rpm -qi hplip | grep '^Ve'

----------------------------------------------------------------------------
(cf. https://bugs.launchpad.net/hplip/+bug/1423220)

Currently HPLIP does not build for SLE12 because
----------------------------------------------------------------------------
$ osc results -v -r SLE_12 Printing hplip              
SLE_12  x86_64  unresolvable: nothing provides cups-devel < 1.6
----------------------------------------------------------------------------
Currently SLE12 is not urgent - as time permits I will
work on it to also make it build correctly on SLE12...
