Problem installing on SteamDeck

[Kamikaze01git]

Describe the bug
when i try to execute the downloaded linux installation file on SteamDeck, nothing happens... when i try to open the file in console, i get following error:
/home/deck/Downloads/RemoteController-linux-amd64: error while loading shared libraries: libwebkit2gtk-4.0.so.37: cannot open shared object file: No such file or directory

i followed the guide from here: https://github.com/PiterWeb/LibreRemotePlay/wiki/installation-&-execution
and also do all steps
sudo usermod -aG input $USER
lsmod | grep uinput
sudo modprobe uinput

To Reproduce
try to execute the downloaded RemoteController-linux-amd64 on a SteamDeck

Expected behavior
a working program after installation, so i can use LibreRemotePlay between two SteamDeck, or between a SteamDeck and a windows pc ;)

Hi, first thank you for taking your time to try LibreRemotePlay. In second place I will try to explain what I think that is going wrong:

LibreRemotePlay uses under the hood your "native" webview in the case of linux is webkitgtk-4.0 by default, the error on the console seems that is caused because webkitgtk for some reason is not installed or maybe there is a different version like webkitgtk-4.1.

I have investigated about webkitgtk on SteamOS and looks that it is not bundled on the OS, but first check by yourself if you have webkit2gtk-4.1 installed (if this is the case I will have to make a custom build for you).

If not you might have to install webkitgtk-4.0 using the package manager.

I think that SteamOS is based on arch so I searched for the package and should be this.
https://archlinux.org/packages/extra/x86_64/webkit2gtk/

Expected behavior a working program after installation, so i can use LibreRemotePlay between two SteamDeck, or between a SteamDeck and a windows pc ;)

If you want to Stream from Windows to SteamDeck you can install the App in Windows and use the Web client in Steam Deck (In generall is better using the web in the case of client but web and desktop are not in the same version so might be more bugs than expected)

Hope this helps you :)

hello and thank you very much for your fast and helpful answer.
i checked all installed packages and you were right: there is no webkitgtk on SteamOS, so i followed your advice and downloaded the mentioned package and installed it with
sudo pacman -U --noconfirm /home/deck/Downloads/webkit2gtk-2.48.3-1-x86_64.pkg.tar.zst

This worked and the package is now installed. BUT... now i get following
/home/deck/Downloads/RemoteController-linux-amd64: error while loading shared libraries: libicui18n.so.76: cannot open shared object file: No such file or directory

i tried RemotePlayTogether from Steam, but my friend and me always had some problems between two SteamDecks. We also tried Sunshine and Moonlight with VPN, but way also a lot of different problems...
parsec do not support linux
and with the git repo RemotePlayWhatever it also does not work proper...
so i was more than happy to try your thing for two SteamDecks.

hopefully i get it to work somehow ;)

Unlucky, I hope you can play together soon.

/home/deck/Downloads/RemoteController-linux-amd64: error while loading shared libraries: libicui18n.so.76: cannot open shared object file: No such file or directory

This is the package that gives libicu18n https://archlinux.org/packages/core/x86_64/icu/
but I have no clue about why is not already installed and why your system needs it.

[Kamikaze01git]

:( ...yeah. Unlucky me run from one problem into the next...
tried to install and run into next error. maybe this is note made for SteamDeck :(

(deck@steamdeck ~)$ sudo pacman -U --noconfirm /home/deck/Downloads/icu-76.1-1-x86_64.pkg.tar.zst

[PiterWeb]

Oh what a pity.
I might cannot help you more with this as I don't have Arch nor SteamOS to advance with this issues. Also is very strange that even Steam Remote Play doesn't work in a SteamDeck.

[Kamikaze01git]

No problem :)
Keep doing, I think this is a great thing anyway.
Thank you so much for your work !!

[PiterWeb]

I have find out other way that could work for you, I had created a .AppImage from the available executable that should bundle all the necesary dependencies to work.

I will upload to releases, I hope it resolves your ploblem.

https://github.com/PiterWeb/LibreRemotePlay/releases/download/release-v3.1/Remote_Controller-x86_64.AppImage

[Kamikaze01git]

thank you so much for your effort,... but i am not that important for an extra solution :)

unfortunately the appimage also not work. :(

this is the output, if youre interested.
but pls dont waste more of your time for me-...
even, if you got it to work, my friend is on holliday and we cant play right now...
maybe you can test it at a later moment when SteamOS is fully released for every PC :)

[PiterWeb]

thank you so much for your effort,... but i am not that important for an extra solution :)

Well I wanted to try this little thing at least.

unfortunately the appimage also not work. :(

Oh :(

this is the output, if youre interested.

Actually I am very interested, the error now at least is Go code so it executes.

but pls dont waste more of your time for me-... even, if you got it to work, my friend is on holliday and we cant play right now... maybe you can test it at a later moment when SteamOS is fully released for every PC :)

Ok don't worry about and thank you for your time

[Kamikaze01git]

no problem mate :)
i will follow your work and maybe use it with windows or maybe Linux handhelds at a later moment in the future ;)
thank YOU for your participation in my problem and your time :)
