Minecraft (ebuild to build deps from source!)

[GummyGum173]

is dev.gentooexperimental.org dead? I fail to install some lib because the site's down (gentooexperimental.org is up though) (jinput)
any chance somebody has the jinput tarball?

[Chewi]

gentooexperimental.org has been known to go down for months at a time. I'm a dev now so I don't really need it any more. I have the tarball but the package needs bumping and possibly even moving into the tree now anyway.

I haven't forgotten about you guys at all but the Java team is really hurting after years of neglect. I'm fighting my way through a backlog to get minecraft-server into the tree once and for all. I almost had it ready when they went and added another bloody dependency in 1.8.3!

Eh? No it doesn't; the dev. machine might (I can't speak to it, especially with all those devs using it for ssh.. ;) but the rest of it's pretty solid ime, including the binhost.

[Chewi]

I didn't realise there was more than one machine behind it. I only used it for dev.

[GummyGum173]

so should I just wait for the java overlay to be updated in the meantime?
By the way, were you successful at running minecraft (the client) on your ARM machine?

[steveL]

Chewi: no worries; just didn't want anyone who might be/consider using it (eg [post=4716038]for binhost[/post]) to be put off.

[shadywack]

Chewi,

Thanks for all your work that you're putting in. You're benefitting the overall gentoo distro immensely and I appreciate it very much.

[Chewi]

so should I just wait for the java overlay to be updated in the meantime?

I've created new jinput and jutils ebuilds that should go into the tree tomorrow once I've tested on x86. To be honest, these actual packages won't help much towards running Minecraft right now because I haven't kept the unbundling up to date. You'll probably need to use the upstream jars for now so all my ebuild does is install the launcher. I'm afraid the server has taken priority but the client will be next. I also want these packages added to support other Java games like Revenge of the Titans and Titan Attacks.

By the way, were you successful at running minecraft (the client) on your ARM machine?

Still haven't tried, primarily because the open GPU drivers for my ARM box are still in a very experimental state. There are active talks to get them into mainline at last though. I'm somewhat confident it could work, I think someone got it going on the Raspberry Pi.

[Chewi]

New ebuilds for jutils and jinput are now in the tree.

Ok, so I've found a fix and a possibly easier way to insert custom libs into minecraft.

I guess you're on ARM, so you'll have to do that:

Shame that apparently there's no way to run that on my Tegra 3 I was sure it also translates it to OpenGLES or something, figures it keeps running on OpenGL, which my drivers don't support, so I get like 1 FPS.
I'll keep updating if I find something.

[geki]

Hi there,
just wondered, if you had a look at this already:

http://forum.lwjgl.org/index.php?PHPSES ... 5#msg21485
https://github.com/LWJGL/lwjgl/blob/master/build.xml

there are extra targets to build against OpenGLES. at least for lwjgl 2.x.

Greeting Gentoo users!!

Trying to install the 1.8.4 overlay ebuild of Minecraft here. I'm receiving this error :

* ERROR: games-server/minecraft-common-20130203::myoverlay failed (prepare phase):
* (no error message)
*
* Call stack:

I've created the games-server/minecraft-server and games-server/minecraft-common copied the ebuilds in those directories and created the manifest. What am I missing here?

Managed to successfully compile after all. I'm still experiencing an odd problem. Trying to start the server as root running the init script /etc/init.d/minecraft-server start

so the server is running. Still I cannot see the local game from my Windows pc on the LAN. When giving a direct connect I get a disconnect error. On the Gentoo side I can see on the minecraft log that a connection attempt was made.

It seems the game is trying to contact com.mojang.authlib.GameProfile@f187d42. Do I need to open some port to Mojang?

[divined]

To any whom it may concern I solved the problem by switching the server to offline-mode. This isn't recommended by Mojang though since now players don't authenticate through it's servers. Has anyone found a better solution?

[Ant P.]

@Chewi:

I went digging through the innards of the vanilla launcher recently for other reasons and now I have some basic understanding of how it works.

Seems like if we want to get the original from-source client ebuild going again, the old hacky wrapper script isn't necessary any more. We can just extract all the bundled libs from the profile json (i.e. ~/.minecraft/versions/1.8.8/1.8.8.json), make ebuilds for those, then have the client ebuild install a gentoo-specific json with the deps omitted since they'll already be in the system classpath.

That sounds important. Maybe trying with this -Xlint:{deprecation,unchecked} flag would fix it?

lwjgl from the chaos overlay also suffers from this.

[Chewi]

After squeegily poked me about this on IRC, I felt bad about it and fixed it later on with a bump to 2.9.3. Sorry it took so long. I can't promise Minecraft that will work any more though.

A tip for anyone else suffering abysmally bad font rendering in the game's launcher — add this to env.d, bashrc or whatever's most appropriate:

Code: Select all

_JAVA_OPTIONS='-Dawt.useSystemAAFontSettings=on'

It doesn't exactly do what the wording implies, but it looks a hell of a lot better than the unhinted, aliased text icedtea (possibly other VMs) outputs by default.

It doesn't exactly do what the wording implies, but it looks a hell of a lot better than the unhinted, aliased text icedtea (possibly other VMs) outputs by default.

Font rendering is undergoing some change at the moment and not just in Java. IcedTea 3.1.0 introduced support for Infinality but this arrived just as FreeType all but dropped Infinality in favour of a new rendering engine. This will become the default in FreeType 2.7 but you can try it now in 2.6.5 with the cleartype_hinting USE flag. I haven't tried it yet and I'd be interested to hear what you think, particular in terms of how it affects Java.

[Ant P.]

I've been watching freetype development for a while; I did have infinality turned on for a long time but I got rid of it when the other big hinting rewrite went into upstream a few months ago, and when the cleartype_hinting flag showed up I turned it on. With it off, things look a bit too odd for my tastes.

Vanilla freetype's rendering is, imo, much nicer than infinality since FT 2.6.2. Infinality doesn't do gamma correction right (or at all) so while it looked fine on a webpage, I could barely tell bold and normal text apart in the console. The contrast improvement with it gone is like night and day and everything looks consistent now.

Java is the one thing on my system that seems to ignore fontconfig settings entirely. I don't know if there's a way to fix that without the infinality stuff, but that setting above at least makes text legible (albeit a bit blurry), which is good enough for me since I'm not looking at AWT UIs most of the day...

Hello everybody

I just upgraded my minecraft-server to version 1.13.1 from the very old version to 1.8.4
I can load into the default world that the installer sets up but I want to load my old world in which I'd put a lot of work in. So i just copied my files from the old /var/lib/minecraft to /var/lib/minecraft-server
The init script gets the game up and running. Nonetheless, it crashes the moment I try to log in from my Windows client. I reckon this has something to do with the old world. Is there process I must follow in order to upgrade it to the latest version?

[Ant P.]

If it's old you'll need to use a tool like MCEdit to convert the save from legacy format to current. Keep a backup of the original.
