[SOLVED] Falkon browser [ex Qupzilla] for Slackware?

Have they done a poor job with "Auxiliary services that talk to Google platforms are stripped out"? Because those deleted steps are calls to chromium.org from within the engine. I'm looking for browswers which don't "talk" with Google platforms. At least Konqueror has webkit support still so I can stay Google free.

How do you know that? org.chromium.Chromium.xxxx is just a reference to a temporary file. The similarity to the web URL chromium.org is completely coincidental and unrelated, as far as I can tell. Unless you have some additional insight into those files that I'm not aware of.

I don't know, but then why would the developers leave "temp" files with Google names laying around? To me it seems like a reasonable conclusion that a backtrace saying that calls to chromium.org are calls, but I see your observation that these are to /dev/shm locations. Since I have two crash reports, I'll go to the Falkon dev site and file for help in figuring this out then. Thanks for your observation. Cheers

It doesn't say chromium.org, it says org.chromium.*. Big difference. "org" is a common prefix in a lot of different systems, like gconf and DBus. It has nothing to do with a web URL. But it would be interesting to see what the Falkon devs have to say about this.

What you see is all perfectly normal behaviour for a browser which is essentially Chromium with a different coating.
I really wouldn't know what the Falkon developers should comment on, to be honest.

just to report that I tested falkon as built from SBo, together with its dependencies, on slackware64-14.2 and it seems to behave fine.

@ponce could you tell me which dependencies you are identifying, since I think I have them all installed. Which qt5 are you using? Cheers

this is the queue created with sqg (/var/lib/sbopkg/queues/falkon.sqf) that I just run with sbopkg on a clean installation

pyudev
python-evdev
graphviz
ninja
python3
meson
libwacom
libinput
libxkbcommon
qt5
extra-cmake-modules
falkon

I'm using the qt5 available on SBo

https://slackbuilds.org/repository/14.2/libraries/qt5/

Well, I have all those dependencies installed. All but qt5 are SBo sourced. Since it will take 24 hours for me to rebuild qt5 on my old Pentium 820D, would you be willing to test replacing qt5 with AlienBob's version and see if there are any issues? If not I'll start the build process. Cheers.

no issues running falkon here when replacing the qt5 built from SBo with Alien Bob's one.

That's exactly what I've done. No problems in 32bit here either.

@ponce @Lsander666 Thanks for testing. I'm totally confused why the Falkon SBo build isn't working on this stock 14.2 64bit with qt5-alien then. But every time I start it and then click in the URL finder it crashes immediately or within a second of stating to display the url destination. I'm starting to wonder if there is an issue with /lib64/libc.so.6 which is a link to libc-2.23.so. The beginning several lines of the crash report all start the same

Time: Mon Feb 25 10:47:38 2019
Qt version: 5.9.6 (compiled with 5.9.6)

What would you suggest as next steps? Cheers

Looks like a graphics driver problem to me.

So I have a NVIDIA GS8400 dual monitor port, using the nouveau driver. Freedesktop nouveau states that all the functions are implemented for this card, except for SLI and TV-Out. Do I need to rebuild the NVIDIA firmware and the whole blacklist process? Thanks

Well, I'm not sure exactly what the process is for switching to the Nvidia driver, but if you think it's worth the effort to get Falkon working, I think that's what you need to do. No guarantees, though.
