I ran with BOX86_LOG=2 and captured the last few calls before the segfault:

A nice. You run Bit Trip Runner :) (out of curiosity, is it fast enough to be playable on the Rock Pi 4B ?).
Now, Skullgirl... So it crash on my2_SDL_LoadWAV_RW? I'll see if I can reproduce, but I only have the Steam version of the game, not the DRM free one from HB, not sure I will be abble to reproduce. But I'll double check that SDL2 function.

Also, can you do a gdb backtrace of the segfault?
from box86.
commented on July 23, 2024
I have the DRM-free version as well, as soon as I can get box86 built I can assist with testing

@CalcProgrammer1, what did you do about libSDL2_locale.so.0? It appears that it's some custom file, not included with normal SDL2.
from box86.
commented on July 23, 2024
Ah right, it's included in the game files (strangely, none of the other forum posts about this mention that...)

I then used dpkg -x to extract the debs and put the .so files in the same path as the included SDL libraries.

Segmentation fault
Which gdb would I use to get a backtrace, @ptitSeb?
Note that on the Pi 4, even getting to this point takes 3 and a half minutes.

Just a note that you can put native x86 libs in /usr/lib/i386-linux-gnu : that should be the standard folder for multiarch libs (and that way, you can ommit the BOX_LD_LIBRARY_PATH var). But maybe its i686-pc-linux-gnu and not i386 on your system?
To use gdb, you shoud use
/media/pi/BF63-269B/SkullGirls $ BOX86_LD_LIBRARY_PATH=pwd/lib/i686-pc-linux-gnu gdb --args ~/src/box86/build/box86 SkullGirls.i686-pc-linux-gnu
then type r to run and bt to get the backtrace when it segfault.
(The lack of DynaRec make the loading time of some games very long, I know. I'll work on a DynaRec eventualy.)

This seems to be somewhere in the VC4 OpenGL driver. It could be interesting if you can try to run with software Mesa or gl4es, to see if the issue is specific to this driver or just box86 feeding incorrect GL data.

Also, I can do some wrapper for the glClearTexImage and friends.

Over on my x86_64 machine with 32 bit libraries installed, I get "CRITICAL: Unable to create SDL Window", which is the same as what I get if I try to run it without box86!

commented on July 23, 2024
I can't find the right function to break on in gdb, but it displays that error somewhere after
#1 0xf7e4681c in LOC_GetLanguageList () at /builddir/SkullGirls/tools/3rdParty/SDL2_locale/source/src/unix/SDL_syslocale.c:86

I don't think this is a box86 issue, but I'd have to run a full i386 version of Ubuntu to work it out...

How would I load a different graphics driver for this on the Pi?

commented on July 23, 2024
I don't know, I don't have any Pi. I think there are some environment variable with Mesa to force software backend, but I'm not sure it does work here.

commented on July 23, 2024
Got it, I think - LIBGL_ALWAYS_SOFTWARE=1 from https://www.mesa3d.org/envvars.html

Hah! Just when I was going to give up, it gets through the intros and then segfaults when using the software renderer.
I wonder if glDebugMessageCallback would have any useful info?

Ah, so there is an issue with the VC4 driver...
And in box86 too it seems. Crash in a callback, from sdl2_mixer, ok. I need to try my Steam version, maybe it'll work.

Skullgirls on Steam is only 64bits now. There is no 32bits binary anymore.
But it does work with box64
I propose this ticket be closed.
