Doesn't work on Linux

[GalecO1987]

Hello, as the title says, I'm a Linux user that play Beat Saber with mods. While the game with other mods work perfectly fine, I'm having some trouble getting bsrpc to work. I installed it using BSManager, and the mod seems to install correctly, but it doesn't make my Discord Rich Presence more detailed as it should. It only shows the default Beat Saber presence, without any of the extra info like the song I'm playing or the difficulty. I even tried using wine-discord-ipc-bridge, but it doesn't fix the issue.

I'm not seeing any error logs, so I'm not sure what's going wrong. Is it possible to somehow make it work on Linux, or am I missing something? I tried to search this issue on Beat Saber Modding Group, but I guess I'm the first to report it?

Here are the logs:

Frankly I had no idea the mod could even run on Linux, I personally have never tried, nor do I know for certain what the issue might be. The only relevant lines in your log are related to DiscordCore, the mod I took over the maintenance of that bsrpc depends on, and this is all the info I have to work with:

^{I do find it rather unsettling that the game is giving you error messages with my exact hard drive path to my project, but that is besides the point.}

The only thing I see is that the error likely originates from the mod not being able to load the Discord Game SDK which is packaged in the release zip of DiscordCore under the Libs/Native folder, and thus it's also extracted there after the mod is installed.

There is something that could be worth a try, but I would not have high hopes. Edit Plugins/DiscordGameSDK.manifest in your install folder, and replace the .dll under "files" with .so, and see if that changes anything. If not, I'm not sure there's much else I can suggest. Most of this stuff was designed to work on Windows, and as much as I hate this OS, I'm not sure how to make any of this modding stuff work under Linux myself.

I replaced the .dll with .so like you asked and unfortunately it didn't help... It gives me the same error.

If not, I'm not sure there's much else I can suggest. Most of this stuff was designed to work on Windows, and as much as I hate this OS, I'm not sure how to make any of this modding stuff work under Linux myself.

Sad, because it's the mod that I really wanted to make it work, but I understand if you can't do this. Maybe someone else would be able to make this work?
Anyway thank you for your reply and thank you for this mod.

Discord RPC in general is notorious for breaking on linux. I too was hoping for some kind of alt arrpc or vencord integration

Someone pointed me to https://github.com/EnderIce2/rpc-bridge which attempts to connect the Windows pipe that this mod probably writes into to the Linux pipe that Discord listens to. I couldn't get it to work though, it looks like https://github.com/WentTheFox/DiscordCore/ has more problems than the pipe. But maybe it helps someone who has more time and motivation to debug.

I am also trying to get this to work on linux and the error I am getting in my logs is this:

[ERROR @ 21:51:30 | DiscordCore] Error starting DiscordClient: InternalError

Running wine-discord-ipc-bridge in debug mode and piping the result into a log file it looks like DiscordCore tries to send client_id of zero, followed by getting no response from discord client:

Pipe Server: Main thread awaiting client connection on \\.\pipe\discord-ipc-0
Client connected
Creating socket
Attempting to connect to /run/user/1000/discord-ipc-0
Connected successfully
31 bytes w->l
<binary>{"v":1,"client_id":"0"}
winread EOF

Not receiving a response to the handshake is probably what causes RegisterSteam to throw an InternalError.
Looking at how DiscordCore first connects - the "client_id": 0 is expected, so it probably happens on Windows too?

Running wine-discord-ipc-bridge the same way but now with Portal: Revolution (the only other game I have currently installed that uses the Game SDK), this is the output:

Pipe Server: Main thread awaiting client connection on \\.\pipe\discord-ipc-0
Client connected
Creating socket
Attempting to connect to /run/user/1000/discord-ipc-0
Connected successfully
48 bytes w->l
<binary>{"v":1,"client_id":"747154846817452045"}
461 bytes l->w
<binary>{"cmd":"DISPATCH","data":{"v":1,"config":{"cdn_host":"cdn.discordapp.com","api_endpoint":"//discordapp.com/api","environment":"production"},"user":{...}},"evt":"READY","nonce":null}
winread EOF

In this case, discord client does respond, seemingly proving that the issue isn't with wine-discord-ipc-bridge.

Still though, this doesn't explain why DiscordCore doesn't work specifically on Linux...
