GOG ubuntu 16.04 libSDL2 error


Recommended Posts

Hi i installed xenonauts from gog, but the game doesn't start because it says

./Xenonauts.bin.x86: error while loading shared libraries: libSDL2-2.0.so.0: cannot open open shared object file: no such file or directory

I checked and the library is installed. How can i resolve?

...so xenonauts need libSDL x86?

You tell me; as I've said "Check with ldd.".

It's simply that the executable name strongly hints at it (also programmers tend to be naturally lazy (as pretty much all humans are) and not do shit properly if they aren't forced to, so given that given that keeping a strong distinction between pointers and intergers in mind, as well as remembering that sizeof long varies, takes some (sometimes significant) effort, chances are the devs didn't bother to do that much and provide only 32bit version of the executable).

On Windows, it doesn't matter all that much, but is quite annoying on Linux.

This is the output of "ldd Xenonauts.bin.x86"

Well, don't know that distro setup, but I'm almost certain those will be 32bit libs.

If you have either 'file' or 'readelf' installed, either should be able to tell if used on one of those paths in the output (in the later case, 'readelf -h' will suffice - in the output 'Class' will either be ELF32 or ELF64).

It uses ELF32

So, they obviously *are* 32bit and a 32bit SDL2 lib is missing.

As I've said, I don't know your distro, so you need to ask on its forum on the proper way of installing it.

A side note: would be very nice if at some point in the future (not necessarily immediate, but reasonably close) Goldhawk would opensource the engine, same way ID Software eventually opensourced its engines (Doom, Quake, etc.).

That does wonders for a game/community longevity.

Solved, now it works!

i just do

sudo apt-get install libsdl2-2.0:i386

about the engine i doubt that it's possible to opensource it. even Goldhawk doesn't have access to the source. It's explained in the development diary, you can find it in "extra" when you start the game.
