[Feature Request] Linux Support

[Henry-Hiles]

Hello! I'm not sure if it's possible, but it would be great if linux support could be added to this app.

I have a linux phone, and there currently aren't any good solitaire games (and this is the best I've seen for Android). Again, I have no GDX knowledge, so this might be impossible, sorry if so. If you can get it compiling for Linux, I can package it as a Flatpak and put it on Flathub, so it can be downloaded on any linux distro. Thanks!

Since libGDX is cross-platform, it should be possible, right?

Probably? Apparently LibGDX already supports Linux on Arm, and the project genarator I used, gdx-liftoff, creates basic setup for cross-compiling lwjgl3 module using construo. I'd been able to create a Linux x64 runnable by simply running ./gradlew packageLinuxX64. I don't know anything about Linux phones though.

A small upadate: I played with the build config a bit and was able to add Linux AARCH64 as a target. Now ./gradlew packageLinuxAARCH64 creates something 🙂. I don't know if that 'something' works though.

If you've pushed that build config change I'll try it on my Linux phone later today :)

I did.

[Henry-Hiles]

I ran it, where does it output to?

[Henry-Hiles]

Hmm.

[Henry-Hiles]

Got a better error:

[Henry-Hiles]

ah

[mimoguz]

But it's there, right?

Or not. It's complaining about ld-linux...

What version of libgdx is used

wait a second, thats not there for me

[Henry-Hiles]

oh did you unpack the jar

[mimoguz]

oh did you unpack the jar

Yes

[Henry-Hiles]

Oh yeah its in the unpacked jar.

[mimoguz]

Maybe that? : https://forums.raspberrypi.com/viewtopic.php?t=357800. 32 bit OS?

[Henry-Hiles]

Certainly I'm not on 32 bit, its arm64

Did you see this? What version of libgdx is being used? Also maybe this? libgdx/libgdx#1127

[Henry-Hiles]

shattered-pixel-dungeon definitely has a working flatpak linux aarch64 build (ive played it)

[mimoguz]

Did you see this? What version of libgdx is being used? Also maybe this? libgdx/libgdx#1127

gdxVersion=1.12.1

Well native libs are there, and linuxX64 build works 😐

[mimoguz]

Quite a late and probably unhelpful addition: I finally grabbed a micro-HDMI adapter, hooked my Raspberry Pi 4 to a monitor, and tried the AARCH64 build there. It just worked:

So, I think the build artifacts are not the issue on your phone.

[Henry-Hiles]

Hmm. Ill test again soon, but maybe libgdx requires glibc rather than musl?

[mimoguz]

maybe libgdx requires glibc rather than musl?

That might be the problem yeah.

[Henry-Hiles]

Great! This means we just need to flatpak it and it'll work I think! (or we need to wait for that issue to br fixed maybe)
