Does this just fail for me or is it a general problem? Any ideas how to fix it?
That »MonoBleedingEdge« name makes me suspicious that this might possibly be a development build…

I'm using arch linux.

Game is crashing here too.

On my side it seems related to an error while reading the alsa.conf file. Strace output snippet:

[i]
openat(AT_FDCWD, "/usr/share/alsa/alsa.conf", O_RDONLY) = 13
fstat(13, {st_mode=S_IFREG|0644, st_size=9625, ...}) = 0
read(13, "#\n# ALSA library configuration "..., 4096) = 4096
--- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=0x13} ---
[/i]

When I move/rename my alsa configuration (e.g. mv /usr/share/alsa/alsa.conf{,.bk} using bash) the game starts but alsa is of course not working anymore, so there is no sound. :-)

Here's my backtrace, too:

I will dive into this once more when I've got the spare time. :-)

Greetings,

Found a workaround.

The Issue

Starting Ara Fell results in a crash:

--- SNIP ---
[mbiberhofer@ajikeshi Ara Fell]$ ./start.sh
Running Ara Fell
Set current directory to /home/mbiberhofer/GOG Games/Ara Fell/game
Found path: /home/mbiberhofer/GOG Games/Ara Fell/game/Ara Fell.x86_64
./start.sh: line 16: 13159 Aborted ./"Ara Fell.x86_64"
--- SNAP ---

The details are: SIGSEGV is emitted while reading in the file "/usr/share/alsa/alsa.conf". See my previous post for the strace output.


The Workaround

I think this bug is specific to games using unity3d -- Tower of Time suffers from the same issue, and this workaround fixed it too.

Your hardware matters: I have a Intel embedded soundchip in my thinkpad ("intel HDA"). Plaese check your hardware! There are multiple configurations in /usr/share/alsa/cards -- please find the one that is applicable for your sound chip.

Everything that follows is specific to intel HDA cards, so don't copy & paste the "HDA-Intel.conf" part if you have a different sound card.

My /usr/share/alsa/alsa.conf starts with the following two blocks.

--- SNIP ---
#
# ALSA library configuration file
#

# pre-load the configuration files

@hooks [
{
func load
files [
"/etc/alsa/conf.d"
"/etc/asound.conf"
"~/.asoundrc"
]
errors false
}
]

# load card-specific configuration files (on request)

cards.@hooks [
{
func load
files [
{
@func concat
strings [
{ @func datadir }
"/cards/aliases.conf"
]
}
]
}
{
func load_for_all_cards
files [
{
@func concat
strings [
{ @func datadir }
"/cards/"
{ @func private_string }
".conf"
]
}
]
errors false
}
]
--- SNAP ---

We have to change these blocks: Remove the whole "cards.@hooks" block and ensure that the "aliases.conf" your card configuration file is loaded in the "@hooks" block by adding it to the list:

--- SNIP ---
#
# ALSA library configuration file
#

# pre-load the configuration files

@hooks [
{
func load
files [
"/etc/alsa/conf.d"
"/etc/asound.conf"
"~/.asoundrc"
"/usr/share/alsa/cards/aliases.conf"
"/usr/share/alsa/cards/HDA-Intel.conf"
]
errors false
}
]
--- SNAP ---

(the bold lines mark the additions to the block)

That's it, you should now be able to start Ara Fell without a crash.

EDIT: What the fuck, I can't post a fucking pastebin link to the files and GOG fucks up my whitespaces when C&P'ing. Well, that's your loss.

Mine is crashing too, but all it says is:

Set current directory to /mypath/AraFell/game
Found path: /mypath/AraFell/game/Ara Fell.x86_64

A blank window appears for a fraction of a second, and then disappears. And that is all that happens. I have tried doing this several times, both from console and by double-clicking on start.sh, using my menu item and even attempting to run Ara Fell.x86_64, but the result is always the same.

How can I find out what the problem is? I'm not sure whether or not it's the same problem you had, and I'm afraid I couldn't quite understand your solution, sorry.

So, I ran 'strace' in the end too (same issue as yourself). It seems that current Unity engine requires OpenGL 3.2+ (I THINK) so check what your system supports. I thought that a pixel-RPG would run on anything really but it appears I need serious (well reasonable) 3D hardware. I imagine this will prove true for any Unity based games.

No problems here running it on slackware64-current and AMD RX 580. You might want to check Unity 3d log for this game. In my case it is written to ~/.config/unity3d/Stegosoft Games/Ara Fell. And yes, modern games built with unity unfortunately don't run on old hardware despite games themselves not being demanding. I learned this after unsuccessfully trying to run a few indie games on an old laptop.

This worked for me! Thanks, friend.
