on ARM linux (raspberry pi) #443

ghost · 2018-10-09T22:24:04Z

Loved this game and your remake. I know its a difficult task, but i think the raspberry pi matches all the specs needed to run these game (opengl include). Could I ask if it possible to compile it on raspberry (with lazarus) and use wine to run it natively (not emulated) like I did with other "windows" arm recompiled apps. It could be an amazing port to ARM. so, if you tell me that its possible than something like that could work I will try it. I know it will try to use some windows API, so I need to know if at least if possible to make it run, theoretically. it could take me a long time to compile it (because of a lack of knowledge), so I need at least some hope before start.

LauraRozier · 2018-10-09T23:12:12Z

With Laz you can cross-compile to any architecture, but the issue is the random bits and bobs of assembler. I think those are x86/x64 only... I could theoretically try to compile it once and try it on my B+
The real issue is that you can not play with "official" releases, as the security check won't allow this.
I did already work on a full-on linux-dist build and it works without wine.

ghost · 2018-10-09T23:23:11Z

Thanks for the quick answer. I follow your work from long time ago. This game has some economic mechanics were never present on another SRT games. if you could test it on your own pi I will appreciate that so much. I have a copy of the game and just need it on my pi because it should can :)

ghost · 2018-10-09T23:29:16Z

No wine? good!! that is an start!

ghost · 2018-10-11T13:36:41Z

could you give me a little explanation of how to compile it? because its different from windows to linux. I dont know how to git revert the files from the replaced .data folder for example (following this guide https://github.com/Kromster80/kam_remake/wiki/ProjectCompilation). I only used git revert before to get revert a commit. please note than I am just a newbie than love this game my mail its salva.liebana@gmail.com . thanks to everything!

ghost · 2018-10-11T13:51:18Z

I use "git pull origin master" just in case it could help... but I barely think that.
so, I continue and when compiling this come out:

LauraRozier · 2018-10-11T15:05:00Z

From Krom his repo you are unable to compile to Linux, this is broken and not supported. I have a fork with a specific branch I was using for Linux compilation.
I am just looking for time (Of which I don't have a lot) to test it on my own Pi, then I could help out.

Hi Thibmo! I know than you dont have so much time to give me some help! I am sorry if I am getting heavy on this, its only because I love this game and want to remind you than I count on you. Ive tested your linux client branch but unsuccesfully :( . seems broken to me, not an arm or x86 warning. just an "Error: Function is already declared".

ghost · 2018-11-10T23:05:46Z

nothing yet? sorry if you find me a little dens. I love to get this game working on rpi

Kromster80 · 2018-11-11T05:55:04Z

@Askmewho please attach the exact error message you are getting. It is behind the hint on the above screenshot ..

I use the branch linux-client on the fork of thibmo

LauraRozier · 2018-11-29T23:33:22Z

Setting up a RPi with guacamole at the moment, crosscompile from the Windows machine just ended up in a linker error so I'll try it this way (saves me having to add yet another monitor to the desk)

KromUtils.pas(62,13) Error: (3120) Function is already declared Public/Forward "SwapInt(var LongWord;var LongWord);" is likely caused by type collision - both Cardinal and NativeUInt map to LongWord on your system. You might need to ensure that WDC conditional define is turned off.

ghost · 2018-12-21T03:33:32Z

Couldnt make it (basically, I dont know how to turn off WCD conditional define on lazarus). thibmo, if you make any progress please contact me, my mail its salva.liebana@gmail.com . thanks for everything guys. you all made the best remake possible for the most underrated RTS game of all time.

LauraRozier · 2018-12-21T08:34:28Z

The WDC define DOES NOT exist within lazarus.
Only the FPC define exists. WDC is a customly set define that is set via the .inc file in the repo root. It is only set when a delphi-specific conditional define is set.

ghost · 2018-12-21T21:32:23Z

ok, btw, whats the opengl needed on this project? because vc4 mesa driver its only 2.1 capable

ghost · 2019-01-17T06:16:14Z

ok, WDC conditionals problem resolved. now its opengl.

LauraRozier · 2019-01-17T08:29:09Z

KaM Remake requires:
– 500MHz or faster processor;
– 256MB or more of RAM;
– 3D graphics accelerator OpenGL 1.4 compliant;
– Sound card.

ghost · 2019-01-17T19:28:04Z

it should work. I will keep trying.

LauraRozier · 2019-01-17T19:58:45Z

Which branch are you using, btw?
I mainly work from the Linux-native-game-client branch on my fork.
It has (most of?) the modifications by Rey and should compile to "normal" GNU/Linux systems.

ghost · 2019-01-19T04:55:23Z

Yes, i am on that branch. could you give me a few instructions of how to compile it, what the project I have to open on lazarus, etc. because its a mess and maybe its not the same procces like on windows compilation.

LauraRozier · 2019-01-19T12:09:08Z

In Laz you just have to open the file KaM_Remake.lpi
Then you compile ot for your system, with Laz you have to clean before you rebuild the sources.

ghost · 2019-03-11T18:01:46Z

Hi, thibmo. One last thing. Have you any linux binary release? I will try it under emulation. It will be easier if you could supply a binary.

LauraRozier · 2019-03-12T15:53:20Z

Sadly I don't. There is also the fact that CPU architectures have to match, if a binary is compiled for x86 it won't run on ARM, etc.

ghost · 2019-03-15T19:47:27Z

Yeah. But i wanna run trought emulation... X86 emulation. But its ok.

ghost · 2021-06-05T01:37:00Z

https://youtu.be/yORdTDzlUds years later. it's now possible!!! that being said rpi4 is too weak on the gpu to run it perfectly, my rk3399 does a much better job. @thibmo @Kromster80
