I just bought this game and when trying to "Launch" a new "Vanilla" game it just crashes with the following ending lines in the Terminal:

[SNAKE2D] ---Core was sucessfully disposed
[S_API] SteamAPI_Init(): SteamAPI_IsSteamRunning() did not locate a running instance of Steam.
[S_API FAIL] SteamAPI_Init() failed
terminate called after throwing an instance of 'std::system_error'
what(): Enable multithreading to use std::thread: Operation not permitted
./start.sh: line 16: 11307 Aborted ./"songsofsyx"

It seems that it's trying to use the Steam API.

Game version: 0.54.18

That actually does it, thanks a bunch! I will note that I had to cd into the "game" sub-folder (where the .jar file sits) before running the JAR directly because otherwise it complains about not being able to find the "res" folder.

This seems like a trivial thing to fix; I hope the developer is aware of this and will take care of it soon.

GOG support will only look at it if you are running a "supported" linux. I created a ticket with Fedora and since that operating system is not supported they could not assist.

I also used the java -Xmx1G -jar ./SongsOfSyx.jar to run the program directly.

Sorry about this, working on a solution! Please note that it's not officially supported on Linux yet due to this.

Hi, you probably wont be able to support every Linux distribution. If this is the only showstopper, it supports linux in my opinion. Plenty of other games have a variety of issues that you can expect most linux users can solve. Thank you for this information. I will get the game now as the linux files seem to be there, which would have been my question.

Only came here to thank joepie91 for the solution and to suggest that - on manjaro - you need to be in the game/ subfolder of songs-of-syx when launching the java executable, because otherwise it wont find the necessary data.

greetings labuvetteducampus

I hoped so, good to know, thanks for telling me!

Seeing if the forum will let me reply to a thread since it's not letting me make one.

*EDIT*
Forgot to specify since the key part was supposed to be in a thread title, but I can run the game if it's on the C:/ drive, but not the E:/ drive (I don't want to run it from the aged C:/ drive.)

When I try to launch the game, nothing happens.

When I try running the game's jar file in cmd, I get an error that says:

snake2d.Errors$DateError: The file or directory does not exist. Try to reinstall the game. path: C:\Users\{Username}\base
at init.paths.Util.checkHard(Util.java:104)
at init.paths.PATHS.<init>(PATHS.java:68)
at init.paths.PATHS.init(PATHS.java:232)
at init.Main.main(Main.java:51)

Make sure that path isn't set to 'read only'. There's no reason why X:\Users\Username\.... should be denied access.

Sounds like an interfering AV busybody. ;)

I still can't load the launcher, but I've found I can launch the game via cmd by making a junction redirecting C:\Users\{Username}\base to the base folder of the game installation (I only tried the menu so far, so it's possible there are other re-directs needed.)
