you're trying to build the linux version or the windows one?
by the looks of it the windows one right?
or have you built both on same system and some left over linux files are interfering with building windows now?
a make clean might get rid of wrong files if it's something like that,
or make deep-clean as those sdl files are only wiped with that

oh and at some point I think it also only worked the second time not the first, not sure if that one ever got fixed

standard make will do windows
make -f linux.mk for a native linux build

note, native linux build still has known bug left so not official yet but pretty close

[torndar]

Got through a bunch, details below but now it's crashing trying to load files on startup. It seems to be looking for "*64" versions of files. I have legal.pal for example but not legal64.pal Another minor issue I hit is that the cd file names are uppercase and it only looks for them in lowercase. I renamed them to lowercase for now but it could be a recurring "bug" for future people trying to run on Linux.

Trying to build the Linux version Linux fedora 6.18.4-200.fc43.x86_64 https://github.com/dkfans/keeperfx/issues/1 SMP PREEMPT_DYNAMIC Thu Jan 8 17:35:49 UTC 2026 x86_64 GNU/Linux

I tried make -f linux.mk at first and it failed super fast (output below) so I tried just "make" and it made it much farther so that's what I posted above. (It was late and I was tired so opened this bug)

I did a bunch of digging and figured out I had to install quite a few packages by hand as build-essential listed in the instructions https://github.com/dkfans/keeperfx/wiki/Building-KeeperFX#building-on-linux isn't available in dnf/on Fedora

I also had to tweak the makefile to add an include

oh you're directly running with files from the original game? that won't work, you do need some of them but you'll also need to download the stable of keeperfx, legal64.pal is in the fx download

and case sensitivity for some files is the last known bug, though the ones bundled with fx are lower case, mostly an issue for specific maps that aren't loading

and yeah I've only tried debian based distros, possible noone tried fedora yet, no idea what xt uses

[torndar]

Got it working by downloading the latest keeperfx build (didn't initially realize I needed that in addtion to the linux executable build) and manually copying the "data" folder contents from the original disk into the data folder of keeperfx.

Unfortunately when I enter the first level I'm stuck scrolling left non-stop. Moving the mouse to the right edge of the screen just scrolls me right. I can't seem to find a dead zone. Should I open a new bug for that or just keep going here?

[Loobinex]

Whatever you prefer, you can also join the discord and talk on tech support.

First thing you could try is see if you use the windows version from the website with Wine, if you then also have this problem, or not.
Also, you could try with and without the -altinput command line option and see if that matters.

[torndar]

The KeeperFX Windows build seems to run fine in Wine. So far I've only opened it long enough to see that it doesn't have the scrolling issue the Linux build does. -altinput didn't make a difference for the Linux build.
