I want to install Krita on a raspberry pi 3 with raspbian Jessie linux, but when I execute the krita.appimage file, i got this error message:

Code: Select all

sudo ./krita-3.1.1-x86_64.appimage
./krita-3.1.1-x86_64.appimage: 1: ./krita-3.1.1-x86_64.appimage: Syntax error: word unexpected (expecting ")")


I installed mypaint and some drawing software without problems, but I like to use krita.... how must I do?

Thanks

Raspberry pi uses the ARM architecture while Krita appimage is made for 64, the other programs you mentioned where likely ported within Raspbian project, (I'm assuming Krita is not on their repo). Even if ported, I doubt it will run efficiently on it.

debian jessie comes with a package for krita that's also built for arm (btw, you meant "x86_64" where you wrote just "64"). Sadly, it's version 2.8.5, which is very, very, very old.

You can build your own krita from source, though.

It should be possible to just use this guide: http://www.davidrevoy.com/article193/gu ... x-for-cats

good luck!

I doubt you'll be able to build Krita 3 for ARM. Krita needs OpenGL 3.0, and ARM boards only have 2.0 ES.

As far as I know, raspberry pi 3 have OpenGL 3.0 ES in the last raspian jessie... but I am not sure if is still a beta or not.
I will try, thanks for the help

Here's a video showing Krita 4.2.9 installed via Flatpak on the Raspberry Pi 4:
https://www.youtube.com/watch?v=4PiE5vKrrNQ

The current version of Krita in Flathub (since that video got recorded) is now 4.4.1.

Note: Lagginess in Krita was observed by the Youtuber, however some of the lagginess was due to him using a VNC connection to view his Raspberry Pi OS desktop. If anyone runs it directly on a physical monitor (no VNC, or remote desktop of any kind), I'd like to hear how that went.

I'm guessing the Youtuber was also running Krita from a MicroSD card. Should it be run from an SSD or spinning rust 2.5" SATA drive, attached to a USB 3.0 port (with an adapter), that might also speed up Krita considerably.

I just tried the Krita from Flathub today, on the latest Raspberry Pi OS 32-bit. I installed Krita with:

Code: Select all

sudo apt install flatpak
sudo flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
sudo flatpak install flathub org.kde.krita
flatpak run org.kde.krita


Note that Krita 4.1.5 is what actually installs, despite the Krita flathub webpage claiming that 4.4.1 is what will be installed (probably true for AMD64).

I took it for a test run, and although you can get Krita to lag a bit, if you do things really fast and jerky (which wouldn't happen on any decent AMD64 machine, like my gen8 i5), by and large Krita is very decently performant. Sometimes the more complex kinds of brush strokes (if large, and grandiose) take a second or two to catch up to your cursor, however this "catch up" happens very smoothly, not all herky jerky, and so it's not really annoying. You can still make really graceful brush strokes.

Any kid whose only computer was a Raspberry Pi 4 (or 400), would very likely be willing to tolerate this lag. It still behaves tastefully.

PS: tested on a Pi4, overclocked to 2.0GHz. No VNC, or other remote desktop technology usage.
