Steam and KSP

[Pythonic456]

Is there a way to run KSP in Steam (with box86) as 32 bit? I know it's not much of an issue with box86, but was wondering if you could, I remember reading a thread on a forum a while ago about someone doing that on a mac...

Thanks in advance!

[ptitSeb]

I haven't tried myself, but I have seen it may start. It seems very slow to load, so not sure it's completly playable yet.

[Pythonic456]

So it can run as 32-bit? How do I make it do that?

[ptitSeb]

You need an old version that still support 32bits I guess.

[Itai-Nelken]

1.4.5 is the oldest version that supports 32bit

[Pythonic456]

Can you get that on Steam? Or how else?

[Pythonic456]

Ah okay, you just use 1.4.3. This happens when running the executable:

Running the Launcher.x86 just aborts

[Itai-Nelken]

more or less same with me, a black window opens but closes after about 30 seconds with no errors.

[Pythonic456]

@ptitSeb You said you've seen it running, can you remember where you saw it doing that please?

Thanks :)

[ptitSeb]

I think it was phoenixbrd user on the discord channel. I don't remember well. I'll check later that game, but I'm some other bug for now.

[Itai-Nelken]

@Pythonic456 I fixed KSP not starting for me by downgrading to mesa 20.2. here are the commands if you need:

git clone https://gitlab.freedesktop.org/mesa/mesa
cd mesa
git checkout 20.2
mkdir build
meson --prefix /usr -Dplatforms=x11 -Dvulkan-drivers= -Ddri-drivers= -Dgallium-drivers=v3d,kmsro,vc4,virgl -Dbuildtype=release build
ninja -C build
sudo ninja -C build install 

Hope this helps!

[Pythonic456]

meson --prefix /usr -Dplatforms=x11 -Dvulkan-drivers= -Ddri-drivers= -Dgallium-drivers=v3d,kmsro,vc4,virgl -Dbuildtype=release build aborts with this error: meson.build:21:0: ERROR: Meson version is 0.49.2 but project requires >= 0.52.

Thanks for your help.

[ptitSeb]

Don't use the meson from apt (so sudo apt remove meson probaly) but the one from python: pip3 install meson Check google for more details.

[Pythonic456]

Okay, now it does this:

[Heasterian]

Did you try sudo apt install --reinstall pkg-config?

[Pythonic456]

Now it does this:

Run-time dependency libdrm found: NO (tried pkgconfig and cmake)

[Itai-Nelken]

Now it does this:

@Pythonic456 try this:

sudo apt install libdrm

[Heasterian]

Go for sudo apt build-dep mesa and sudo apt install libxcb-shm0-dev. It should install all dependencies.

[Pythonic456]

Thank you for your continuing help.

Now it does this when running the KSP.x86 executable:

Some info on this setup:

I'm doing this in a chroot, on a RPi 4B, (I'm just using the chroot to contain it), and here's the command I used to create this chroot: sudo debootstrap --variant=minbase buster rpios http://raspbian.raspberrypi.org/raspbian/ I was just thinking that the --variant=minbase might have not installed some libs and things, so I was wondering if this is the cause of the errors?

When running the Launcher.x86, this happens:

What do I need to do next?

Thanks :)

[Pythonic456]

@Itai-Nelken Can you describe exactly how you got it to work?

Thanks!

[Itai-Nelken]

@Pythonic456 it never really worked for me, the farthest I got is the 'new game' menu after downgrading to mesa 20.2, than it crashed. now it opening it a black window appears for a few seconds and disappears without any errors. when it did work, it took over a hour to load, but rpinews says it should take a few minutes to load, so I have no idea what is happening and why it isn't loading properly.

[Pythonic456]

Do you think it is possible for it to work though?

Thanks :)

[Itai-Nelken]

Do you think it is possible for it to work though?

@Pythonic456 rpinews and phoenixbyrd say it runs.

for me it aborts here:

Importing game controller configs
Aborted

[Pythonic456]

Same for me.

Thanks anyway.

[ptitSeb]

Yeah, I also have the Abort message on my side. I'll see if I can debug it, but no promesses, unity games are still difficult to debug.

[Pythonic456]

Thanks :+1:

[Itai-Nelken]

Thanks!

[ptitSeb]

I got the old Linux 32bits version to works. Here in a 800x600 Windows on Pi4/TwisterOS. (It does segfault at exit, but game itself seems to run). I haven't tried the Steam/Windows version yet.

[Pythonic456]

So you have to use TwisterOS?

Thanks :)

[ptitSeb]

So you have to use TwisterOS?

I don't know, I don't test on twenty thousand OS.... I just tested on TwisterOS. I assume it can work elsewhere, as long as you have box86 and a good build of mesa.
