"Can't determine version of poppler-qt5" on Arch

[Kyuuhachi]

I'm trying to install this (for Frescobaldi), but it won't build.

I think this is the same issue as #24, but a little more detailed.

Hello,
I'm running ubuntu 16.04 and want to install frescobaldi3 but buiding python-poppler-qt5 is not possible : sip error , I get that
building 'popplerqt5' extension
/usr/bin/sip -I /usr/share/sip -t POPPLER_V0_28_0 -c build/temp.linux-x86_64-3.5 -b build/temp.linux-x86_64-3.5/poppler-qt5.sbf -I /usr/share/sip/PyQt5 -n PyQt5.sip -t WS_X11 -t Qt_5_11_2 poppler-qt5.sip
sip: Usage: sip [-h] [-V] [-a file] [-b file] [-B tag] [-c dir] [-d file] [-e] [-g] [-I dir] [-j #] [-k] [-m file] [-o] [-p module] [-P] [-r] [-s suffix] [-t tag] [-w] [-x feature] [-X id:file] [-z file] [@file] [file]
error: command '/usr/bin/sip' failed with exit status 1

And my system only offers qt4 version.
Worst thing : i can install again frescobaldi 2.20, that doesn't work.
Frescobaldi3 launches but instead of the aperçu, I have the following text in the window :
impossible de charger le module popplerqt5 (fail to load popplerqt5 module)
You must notice that I do not know anything about python, just type commands.
So I'm in pain and I'm in late to write music !
So, if anyone has a solution or a module compiled for ubuntu 16.04, it would be very kind to give me some help
cordialement,

I don't think you can build python-poppler-qt5 if your system is missing qt5...
If you can't upgrade your Ubuntu 16.04, use a virtual machine to run Ubuntu 18.04, where Frescobaldi 3 is packaged.

Can't determine version of poppler-qt5 was causing me issues also.

I'm trying to use python-poppler-qt5 for an application targetting windows, so I'm using MSYS2. So for me, the resolution to this issue was simply:

pacman -S mingw-w64-x86_64-pkg-config

I suspect something similar may help, when installing in arch linux.

edit: .. and the resolution came about because the setup.py script was failing trying to subprocess-call pkg-config, which wasn't installed and doesn't seem to be an explicit dependency called out in the python-poppler-qt5 INSTALL documentation.

Thanks, I was testing the build in a brand new ubuntu 20.04 container where pkg-config was not installed and I got the same error. After installing the package I could go on.
