The Re-Volt Hideout

Hello, I'm currently trying to run rvgl on archlinux arm.
the platform is Crostini on Chromebook.
When I tried it on Debian on Crostini and installed the odroid version, it worked without much hassle, so the problem doesn't seem to be on the platform.
I installed the x86-64 version from aur, and then overwritten the binary from the raspbian deb file. To my understanding, anything other than the binary itself is mostly compatible or just identical...
However, it crashes right after the second splash screen, before the one that utilizes game engine itself.

the message for the crash is as follows: The binary also doesn't recognize fluidsynth library. It seems it's because the version is 2 on arch linux, but I believe it doesn't matter because it's only optional dependency anyways.

Hi, I really don't know but the first that came up is to try to set Shaders = 1 to 0 in rvgl.ini located in the profiles folder..

It's not there in the folder. Probably not created yet, because it wasn't properly executed before?

I can send the *.ini, to try it out. Do you have Discord?

In recent RVGL versions, it is ensured that the file is always created before exit. However you're using the ODROID build which is a bit out of date. A crash just after the splash screen could mean missing game assets, or it could be shaders related like javildesign suggested. Can you get the re-volt.log file generated in the profiles folder?

EDIT: I just noticed that build 19.0430a is available for ODROID:

Is that the build you're using?

Here's the log on pastebin.
I have now overwritten the folder with everything from the odroid package, so it might not show the same as the aur package.

Yes, that is exact one I've been using.

Start the game and close it before it crashes. It should generate the rvgl.ini config file. Then edit it and set "EnableUBO = 0". This disables Uniform Buffer Objects which are poorly supported by several GPU drivers. If it still doesn't work, as a last resort you can disable shaders altogether ("Shaders = 0"), but I believe this won't be required.

I was able to kill it with "/opt/rvgl/rvgl & sleep 1 ; killall rvgl" and rvgl.ini was successfully created.
Just disabling UBO did not get the program running - I had to disable the shader entirely.
The red car with the star on the roof in the map "Toys in the Hood 1" does not exist. I'm not sure whether it's ordinary thing or not in RVGL.

- Below are just in case someone gets curious about it. -
The device I use is Asus Chromebook Flip C101PA, with RK3399 SoC.
Crostini doesn't have hardware acceleration for graphics for this device yet, so it runs quite slow. 15-20 FPS most of the time, afaict.
Certainly less than optimal, but okay for casual gaming
(Google says hardware acceleration will be there soon™)
The framerate doesn't differ much between Debian and Arch.

Maybe I could create a package "rvgl-bin-arm" on aur

No hardware acceleration? The RK3399 should have Mali-T860MP4, which is a pretty good GPU. It's a shame RVGL can't utilize it. Dang it Google. Although, the Gallium LLVMpipe driver does expose OpenGL 3.1 functionality, including shader support, so I'm not sure what's causing it to fail.

You probably have Instances turned off (Options -> Video Settings -> Render Settings).

If you need an up-to-date build, you can contact meveric from the ODROID forum or post in the RVGL thread.

I have no idea maybe something to do with the versions of LLVM oslt? It worked fine with Debian, and I would assume no one has tried it with Arch x64 gallium...

Indeed, that fixed the problem. I forgot to mention that the framerate was when almost every option turned off, except medium range rendering and skid mark on. The instance option did not affect much on the performance.

I think I could just fetch the .deb file and extract the binary, and reusing anything else from current aur package.
