slim down falkon dependencies

black-clover · 02-08-2019, 11:47 AM

hello,

I want to install the Falkon browser on a minimal Debian testing machine.
Right now when I check the install it says I have to install.

Code:

root@mac:/# apt install falkon

which seems like a lot of stuff.
I have already disabled installing "suggested" and "recomended" packages in apt.
what makes me curious is that on A Linuxrch the list of dependencies for Falkon is rather small:

qt5-svg
qt5-webengine
qt5-x11extras
extra-cmake-modules (make)
kwallet (make)
libgnome-keyring (make)
pyside2 (make)
qt5-tools (make)
shiboken2 (make)

whereas the Debian website lists more:

my question is:

Is there a way to slim down the number of packages installed without affecting Falkon functionality?

Not in my opinion. Of course you could miss out the dependencies that involve specific functionality that you would never use (and change the package control file to exclude these as dependencies) but you've have to be very knowledgeable about the program and prepared for error messages about missing libraries.

Naturally, the number of dependencies a package will want to install depends on how many of these dependencies already exist on your system. The fact that you're running a minimal Debian system may explain why there are so many dependencies listed and also why less are listed on your other system which may have many already installed.

What is "A Linuxrch"?

ondoho · 02-08-2019, 12:49 PM

^ i think they mean "ArchLinux"

anyhow, it's quite possible that a simple "depends on KDE" just wants to pull in all of KDE, which is a lot.
But falkon does not require the whole KDE desktop to function correctly.

anyhow, i'd look at falkon's PKGBUILD from the AUR, maybe you can figure out how to adapt that to build from source on debian.

Thanks for the feedback,

yes, I meant Arch Linux, sorry about the misspell.
AUR seems like a good starting point.
Seems like starting with the minimal deps listed in Arch Linux package description and going up by trial and error until it works might be the way to go.
Also, on the same system, the difference in the size of MB download required compared to other browsers is staggering:

falkon 272
chromium 191
firefox 171
epiphany 84
midori 82
luakit 75

Geez, I just drilled down the rabbit hole for falkon (3.0.1) on slackbuilds.

Code:

qt5 (5.9.7)
extra-cmake-modules (5.51.0) 
libxkbcommon (0.8.2)
libinput (1.12.6)
graphviz (2.40.1)
meson (0.49.0)
python3 (3.6.7)
ninja (1.9.0)
pyudev (0.21.0)
python-evdev (1.1.2)
libwacom (0.32)

Not too bad, but this is probably in addition to a regular, full installation of 14.2, which I never do. I usually eliminate KDE entirely. Probably need to remove KDE4 for qt5?

Maybe dillo instead.

not sure what you're on about, but i have falkon installed on my vanilla archlinux system and it definitely did not pull in 272 MiB of dependencies.
It depends only on "qt5-webengine qt5-x11extras qt5-svg" and its own install size is 11.72 MiB.
It is definitely lighter in every sense compared to the big players chrom* and *fox.

yes, the amount of download required is what surprised me too, expecially considering I have suggested and recommended packages turned off in apt configuration.
It is a very simple Debian Testing machine with Jwm and little else.
