Linux - Symbol Lookup error

[apricot79]

Firstly, thank you so much for your effords on this. Having some trouble getting this to work on my linux machine. after installing mono-complete according to the instructions, making sure steam is running and making the .sh file executable, bash returns a symbol lookup error.

./Duckgame.sh
...
mono:symbol lookup error: /.../DuckGameRebuilt/libFNA3D.so.0: undefined symbol: SDL_GetWindowSizeInPixels

went and made sure that libsdl2-2.0-0 was installed.

have I missed a step?

Thanks for any assistance.

I just tested on Ubuntu latest and had to install both libsdl2-dev and libsdl2-2.0-0. Try installing libsdl2-dev.

Thank you for suggesting this. Just tried it, but I'm still getting the error. Am I missing some other dependency, or is it an issue with mono?

[klof44]

I am unable to recreate your issue and cannot find any other occurrence of it so any additional information would be useful.

@apricot79 could you provide the version of your system package of libsdl2-2.0-0? what distro are you using?

[apricot79]

of course,
Package: libsdl2-2.0-0
Version: 2.0.20+dfsg-2ubuntu1.22.04.1
also
Package: libsdl2-dev
Version: 2.0.20+dfsg-2ubuntu1.22.04.1

Running Mint 21.2 Cinnamon
Kernel: 6.8.0-52-generic
AMD Ryzen 7 6800H with Radeon Graphics × 8

Thank you for your time.

are you sure mono is installed from monoproject and not from the system package? you can do apt show mono-complete and see the APT-Sources section to see what repo it's installed from

[apricot79]

apt says:
Source: mono
Maintainer: Debian Mono Group pkg-mono-group@lists.alioth.debian.org

[othello777]

no I mean the APT-Sources, found a lot closer to the bottom. I think that's correct though. I suppose I'll have to test with a fresh install of linux mint 21 to see if I can reproduce this

[apricot79]

apt says:
APT-Sources: https://download.mono-project.com/repo/ubuntu stable-focal/main amd64 Packages

You might be right. In the meantime, I decided to just proton the mod via steam. Absolutely love it. Thank you for responding.

Might want to try this again when we push the SDL3 Update Later, https://github.com/TheFlyingFoool/DuckGameRebuilt/tree/SDL3
