FreeType DllNotFoundExceptionon on Linux Headless

[zahndy]

Describe the bug?

Similar to #1241
Instantly crashes upon launch on a fresh installation.
Complains its missing freetype even though "freetype6.so" is present under "/Headless".

To Reproduce

• Install fedora linux and update packages.
• Install mono-devel.
• Install steamcmd.
• Install Headless:

/home/zahndy/steamcmd/steamcmd.sh +@sSteamCmdForcePlatformType linux
+force_install_dir "/home/zahndy/resonite_test/"
+login #redactedusername #redacteduserpass
+app_license_request 2519830
+app_update 2519830 -beta headless -betapassword #redactedbetapassword validate
+quit

• Run Headless:

mono Resonite.exe

Expected behavior

Headless client starting up without a world loaded.

Can you try running the headless like this:
MONO_LOG_LEVEL=debug mono Resonite.exe
This will show where mono is looking for which library and why it can't load any given one and might help debug this issue quicker.

[zahndy]

You probably only need the end but here's the entire output.
MonoDebugResonite.txt

[Nutcake]

Looks like freetype6 requires libbz2:

Mono: DllImport error loading library '/home/zahndy/resonite_test/Headless/libfreetype6.so': 'libbz2.so.1.0: cannot open shared object file: No such file or directory'.

Try installing the bzip2-libs package through dnf.

[zahndy]

That one already seems to be installed?

zahndy@fedora:~/resonite_test/Headless$ sudo dnf install bzip2-libs 
Last metadata expiration check: 1:20:11 ago on Sun 28 Jan 2024 05:06:38 PM CET.
Package bzip2-libs-1.0.8-16.fc39.x86_64 is already installed.
Dependencies resolved.
Nothing to do.
Complete! 

[Nutcake]

Looking at my own Fedora install here, it looks like there is a symbolic link for libbz2.so.1, however Resonite looks for libbz2.so.1.0 instead. Can you try creating a link between them like so:
sudo ln -s /usr/lib64/libbz2.so.1 /usr/lib64/libbz2.so.1.0

[zahndy]

That fixes it, headless is running now.
fedora - 2024.1.27.1114 - 2024-01-28 18_47_38.log
Thanks~

[Nutcake]

Great! You should probably close this issue then, since it is resolved.

[zahndy]

Alright, just still wondering why it suddenly stopped working, If its a fedora specific issue and If I have to keep creating the link on clean fedora going forward.

[Nutcake]

It is a fedora specific issue, yes. Most other distributions create links to all different version formats like so:

You likely wont have to recreate the link in the future, as it points to the *.1 link which automatically gets updated to point to the latest version by your package manager.
