Segfault on Fedora 31

Attempted to download the prebuilt binary and run it but got this error:

[Qwertie-]

I just built the tool from source and it works fine.

[tom-r]

I have the same issue on Fedora 31 with the delivered binary.
I think you should compile & link it with static libraries to include the dependencies.

1. It searches a path /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders.cache for that pixbuf thing...
   /usr/lib/x86_64-linux-gnu/ does not exist on Fedora31. The installation is in /usr/lib64/...
   OK, you can set a link from /usr/lib to /usr/lib64 , but all those font.config errors/warnings remain and also the segmentation fault at the very end
   So : the binary does not work under Fedora 31 !

2. Manual compilation :
   the installation instructions in Readme.md for Fedora are crab
   Duplicated, all in one line, dependencies missing,...
   Quote :
   On Fedora: sudo dnf install sudo dnf install qt5-qttools-devel python3-devel make ln -s /usr/bin/lrelease-qt5 /usr/bin/lrelease

---

At least packages sip and upx and gdk-pixbuf2 must be added.
I'm still failing to compile on my own ...
Currently I'm struggling on the 'make deps dist', because of more missing dependency ...

ModuleNotFoundError: No module named 'PyQt5.sip'
make: *** [Makefile:16: gui/mainwindow.py] Fehler 1

Kind of a nightmare ...

Please fix.

BR,
Thomas

[Informatic]

Indeed, sadly PyInstaller builds are a nightmare on Linux. I tried using staticx but failed miserably. Maybe migrating to appimage/snap or some other similar technology might be a good idea, as these start to get some wider adoption. Patches are welcome.

Regarding Fedora 31 - have you installed python3-qt5 and/or python3-qt5-sip packages? (not sure how pyqt5 is split up on Fedora) Nevermind - these should be installed with all requirements.txt dependencies when you run make deps. Did you do that?

[tom-r]

Hi,
I had installed python3-qt5 but this interfered with the installation via requirements.txt
there is no python3-qt5-sip, it's called python3-pyqt5-sip. And this is still installed.
So I uninstalled the official python3-qt5 package and tried to rebuild it with the make deps.
make deps worked fine now without errors.
Even make dist does finish but with warnings, and there I'm stuck (and I have no clue how to fix it). This is the output of make dist. Please note the sip-warning...

Sorry I'm a python novice, all I know is, that it is "a programming language". I can't help you much.
It would be different story with C and C++ ...
Thanks for looking into it ...

[ricki-z]

@tom-r could you please try to reformat your comment? This is difficult to read at the moment.

[tom-r]

done ...

[ricki-z]

I hace checked the install instructions. They should now work with Fedora 31. Can you test this?
And there is an additionally download of the binary for Fedora 31.

[tom-r]

Hi,
thanks for the quick fix. Here is an intermediate result :
the fedora31 binary starts w/o problems now on my system.
I don't have the nodemcu here at the moment, I will test to flash it on friday and come back with an answer.
I will also test & try to compile on friday according to your compile instructions.

BR,
Thomas

[tom-r]

the given fedora 31 binary is working, I can flash the esp8266.
Compiling :
Still does not work.
I cannot use mkvirtualenv, not found...
make deps installed 2 more packages, and reports no errors
make dist still hat the same 3 warnings
make run still crashes ...
I did a make clean in between ..
But it's not so important right now, I can use the binary.
Here comes the shell output :
