Cannot build python-poppler-qt5: error "sip: QDomElement is undefined"

[GvMariani]

Trying to build a (rpm) package of python-poppler-qt5 for the still upcoming Rosa Linux Fresh 2016.1 (a Mandriva derivative, sibiling of Mageia and OpenMandriva) on x86_64.

The build process fails after the "python3 setup.py build build_ext --qmake-bin=/usr/bin/qmake-qt5" command with this error message (full log attached):

---

sip: QDomElement is undefined
error: command '/usr/bin/sip3' failed with exit status 1

---

The distro rules allow for a side-to-side installation of python 2.x and python 3.x: the packages related to the first one have names "python-xxx-yyy", while the packages related to the latter one have names "python3-xxx-yyy".
The same is true for Qt4 and Qt5 stuff: I already had to add the above "build_ext --qmake-bin=/usr/bin/qmake-qt5" to the build command line, otherwise the build would fail with the error "Unsupported Qt version", because it finds the old Qt4 and not the newer (installed) Qt5.
So I have on my disk both PyQt4 and PyQt5, for both python versions: python-qt4 (ver 4.12) - python-qt5 (ver. 5.8.1); and python3-qt4 (ver 4.12) - python3-qt5 (ver. 5.8.1). The packages also differs on what they are exporting to other python packages: eg. the python-qt5 one exports PyQt5, while the python3-qt5 exports Py3Qt5...

I don't know much about python, but I would guess that setup.py need to know about this trick with the module names...

Forgot to add:
using latest 0.24.2 release.

[smarshall54]

Having the same issue here. version 0.24.2

arch linux 4.11.3

similar setup with qt4 and 5 installed through anaconda

The only way I found to fix this was to

1. Install PyQt with pip
2. build the code from source, first fixing types.sip as per

https://trac.macports.org/ticket/55014

3. build with

CFLAGS=-std=c++11 QT_SELECT=5 python3 setup.py install

@wbsoft this is still broken.
@philgooch I think that's a whole different issue.

Have trying to install this package for a couple of hours now, but it seems to halt on the following.

PyQt5==5.11.3

And also i cannot find poppler-qt5.pc file to add to the PKG_CONFIG search path.

I also tried building it from source with changes mentioned here https://trac.macports.org/ticket/55014 originating from https://github.com/wbsoft/python-poppler-qt5/issues/15

Is it a issue with setuptools or sip? I am without any more clues.

Edit: On Macos High Sierra 10.13.6

@adibub It seems you must install poppler-qt5 from macports?

I don't use Mac. In Linux (Fedora) that file is provided by poppler-qt5-devel:

$ rpm -ql poppler-qt5-devel | grep 'poppler-qt5.pc'
/usr/lib64/pkgconfig/poppler-qt5.pc

[adibub]

Yes! That seems to work. Thx! tor. 10. jan. 2019 kl. 12:35 skrev Federico Bruni <notifications@github.com

the original problem could be that QtXml was not available.

[Zakorak]

@fedelibre I have the exact same error as @adibub but for Windows.

Any idea how to fix it? I have been stuck for hours and I tried to install various versions of Poppler from the internet (which include poppler-qt5) and then added the bin to my PATH but it hasn't worked.

[adibub]

Have you tried installing it with winGW or another compiler? Do you have the log from the failed installation? tir. 3. des. 2019 kl. 22:15 skrev Zakorak <notifications@github.com>:

I haven't tried but I dont really know how, Im very new to coding.
Here is the error when i try to pip install python-poppler-qt5, I made of post on stackoverflow for help but no one responded.

Thanks for the reply @adibub

@Zakorak The problem of python-poppler-qt5 is that it's not a pure python module, but it needs to be compiled and the build works rather easily only on Linux. That's why we should provide ready wheels for as many os/architectures as possible. You can see an example here.

I tried building the wheels but it's not that easy:

• https://github.com/frescobaldi/python-poppler-qt5/wiki/Build-wheels-using-manylinux
• https://github.com/frescobaldi/python-poppler-qt5/wiki/Build-wheels-in-CentOS-7
• https://discuss.python.org/t/building-wheels-for-a-python3-qt5-project/2020

This forum contains many interesting discussions on the subject:
https://discuss.python.org/c/packaging

You may read that the manylinux project is stuck. IIRC there are other tools being developed, but I don't know what is recommended today.

I'm now working other stuff for Frescobaldi so if you want to dig into this issue please do!

Closing; this looks like missing dependencies, you need poppler-qt5 and qt5-qtxml (or such).
