[Solved] Buggy self compiled v1.0 / Nightlies / OXCE on Linux

[incas]

I compiled the game often in the past without any issues. Now I have massive issues with scrolling, mouse wheel usage and sfx sound.
I'm on Fedora Linux and compile with Meridian's or wiki instructions without any errors.

Strangely when I use the openxcom Linux-Appimage it works fine. https://openxcom.org/download/nightlies/OpenXcom_20210611_8d45159bf_x86-64.AppImage
I compiled the exact same commit hash and again problems. Is it some compiler or library problem?

Edit: Problems are mostly noticeable on Battlescape. Scrolling to the sides is very erratic with the mouse. Mousewheel to change levels is moving the screen to the side. Sfx begin to deteriorate after a while. Mousewheel usage for things like changing manufacturing units (tested in XPZ) not working either in Geoscape.

found SDL 1.2.56 (/usr/lib64:/usr/include/SDL)

...looks strange. As far as I know, latest SDL1 version is 1.2.15

Just googling SDL 1.2.56 pointed me to: https://github.com/libsdl-org/sdl12-compat

So probably you're using (or being forced to use by your OS) sdl12-compat instead of SDL1... which hasn't been tested.

That might be it. There is no SDL1 in the repositories
only this

sdl12-compat-devel.x86_64 : Files to develop SDL 1.2 applications using SDL 2.0

https://fedoraproject.org/wiki/Changes/SDL12onSDL2

SDL 1.2 development ended long ago, with SDL 2.0 replacing it. However, many older games still use SDL 1.2 and cannot change to SDL 2.0. In order to help move SDL 1.2 games into the modern world, let's replace SDL 1.2 with sdl12-compat, which uses SDL 2.0.

User Experience

There shouldn't be a noticeable user impact, other than possibly a smoother experience because applications are using SDL 2.0.

Huh?

Damn. Will it work/compile correctly perhaps with SDL 2 installed or do I need to compile SDL 1 myself? Hmm.

[Meridian]

Out of the box, it won't compile with SDL2.

Found it here, hopefully I can make it work with that. The sdl devs seem to hate, that people still  use 1.2

I think Opengl needs to be build with sdl 1.2 as well for OpenXcom to build. I give up. I'll use Wine...

No need to use Wine unless you really want to. You can grab a "bionic" image from https://lxnt.wtf/oxem/#/Extended - works just fine directly on Linux.

Not sure how it was build but I tried 7.5.3 (for XPZ) and it is buggy for me too.
So only the appimage of the older version and Wine work without the issues it seems.

I've opened a bug on sdl12-compat for you: https://github.com/libsdl-org/sdl12-compat/issues/215
Can you post your system info? (Fedora version, SDL2 version, etc)

[incas]

Thank you! I'll post it to Github.
