Assetto Corsa Server

[Kroustalo]

Good afternoon, I'm experimenting with an Assetto Corsa Server running on my RPI4 running ubuntu server Ubuntu 20.04.3 LTS aarch64 but turns out that the linux excecutable is x86 (tested with a vm). I installed box64 and box86 and I came up with this...

box64 acServer
Dynarec for ARM64, with extension: ASIMD CRC32 PageSize:4096
Box64 with Dynarec v0.1.7 40c5824 built on Dec 11 2021 23:16:22
Using default BOX64_LD_LIBRARY_PATH: ./:lib/:lib64/:x86_64/:bin64/:libs64/
Using default BOX64_PATH: ./:bin/
Counted 26 Env var
Looking for acServer
This is a 32bits ELF! box64 can only run 64bits ELF (/home/user/acs/64/acServer)!
Error: reading elf header of /home/user/acs/64/acServer, try to launch using box86 instead
Box86 with Dynarec v0.2.5 a1aac43a built on Dec 12 2021 12:20:51

So here we are... I'm not sure if it is actually running or is it bugged due to the program or the emilator but anyways, I decided to give it a shot here...

I'm attaching the excecutable's for debuging since it is standalone and does not require steam or the game itself to run assetto server test.zip (It's the default server config)

Thanks in advance!

did you try running it with box86 instead of box64?

[Kroustalo]

Box86 runs the last line of the posted output. box64 does it automatically since both are installed.

[Hacker1245]

what if you try to run it with box86 manually? also does it say anything else afterwards?

[Kroustalo]

Kroustalo@Issue:~$ ./acServer

Kroustalo@Issue:~$ box86 acServer
Box86 with Dynarec v0.2.5 a1aac43a built on Dec 12 2021 12:20:51

Nothing afterwards. Ι also attached the files to do your own testing...

Okay, I did some research and I found out that the server is only 32-bit (ignore the "64 bit" version)

I tried to run the debugger and I came up with this

BOX86_LOG=1 box86 ./acServer
Debug level is 1

This is where I am now...

Does this server runs now, with latest box86? Can this ticket be closed?

[Kroustalo]

Haven't checked this since. Give me a couple of days to set it up again because I don't have access to my pi right now. I'll update soon.

I tried to do a fresh install of box86 on Ubuntu 22.04 but it still not running...

$ lsb_release -a

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 22.04.1 LTS
Release:        22.04
Codename:       jammy

But this time I got a different responce...

Ah, go runtime. I have to study this, there are a few tickets of go stuff not working properly.
