Reinstalling jre11-openjdk did the trick. Thank you very much!

@Tio, a clean install of the jre11-openjdk package -which already is a dependency of my package- should set everything up for you. It installs the JRE in /usr/lib/jvm/java-11-openjdk/. Additionally, you may want to set the value of the environment variable$JAVA_HOME (in your ~/.bash_profile or ~/.bashrc, or simply in your terminal, but this is not permanent) like this:

export JAVA_HOME=/usr/lib/jvm/java-11-openjdk/

but this is not strictly necessary, as the jre11-openjdk already adds the binaries to the $PATH.

Tio commented on 2020-09-15 11:09 (UTC)

Ok. I do not know how to do these...but thank you for the answer.

langurmonkey commented on 2020-09-14 07:03 (UTC) (edited on 2020-09-14 07:57 (UTC) by langurmonkey)

Tio, you either need the $JAVA_HOME variable pointing to your Java 11 installation, or the java executable in your $PATH.

Tio commented on 2020-09-14 02:03 (UTC)

Hi. I already have jre11. I removed jre8 so that perhaps it will use jre11. However now I get this error:

[tio@tio-pc ~]$ gaiasky
/usr/bin/gaiasky: line 80: java: command not found

langurmonkey commented on 2020-09-13 18:29 (UTC) (edited on 2020-09-14 07:57 (UTC) by langurmonkey)

@Tio you are using the jre 8 to run it, but should be using at least jre 11 (which is a dependency). Check your java installations and make sure you have the right version. You can check the gaiasky script itself to see how the jre is chosen. Maybe you have Java 8 in your $JAVA_HOME or $JRE_HOME vars.

Tio commented on 2020-09-12 17:04 (UTC)

Wanted to say I get this error:

Error: A JNI error has occurred, please check your installation and try again

gosi commented on 2020-01-29 21:54 (UTC)

No, sorry everything is ok. I just thought the older/newer mismatch is because of the "typo" in pkgver as it is not like the source version. But apparently this is on purpose.

langurmonkey commented on 2020-01-29 09:38 (UTC)

@gosi, I'm a bit confused now, I changed the hyphen to an underscore following the guidelines here:

What is then the right way to go?

gosi commented on 2020-01-28 19:04 (UTC)

gaiasky: local ( is newer than AUR (2.2.4_1.a169540c8-1)

5 days Fix previous release 2.2.4-1

Almost: pkgver=2.2.4_1.a169540c8

that should be: pkgver=2.2.4-1.a169540c8

langurmonkey commented on 2019-08-19 08:08 (UTC)

@pancakes, just updated it. The script that generates the AUR package crashed and I didn't care to check the logs. Thanks!

pancakes commented on 2019-08-15 11:03 (UTC) (edited on 2019-08-15 11:04 (UTC) by pancakes)

@langurmonkey: .SRCINFO should be updated - otherwise it still lists jre8-openjdk as a dependency instead of jre11 (and fails to install on my machine).

langurmonkey commented on 2018-10-18 12:18 (UTC)

Ok, I see. Libgdx's Linux backend uses xorg-xrandr to get the display modes. I will update the package, thanks!

Hey, sorry for answering so late... Somehow I have missed your reply. I just wanted to reinstall gaiasky and recognized the same error again. After installing xorg-xrandr it was resolved. At this point this is all I can say, because I have forgotten the exact way I got to this solution. I will take a further look...

Edit: Here is some more Information at StackOverflow

langurmonkey commented on 2018-05-01 18:26 (UTC)

@StarPicard, how is xorg-xrandr a dependency? I don't see any connection between the randr command line utils and gaiasky. Could you elaborate?

jbehmel commented on 2018-04-29 14:00 (UTC)

Hey, first of all: Thank You for maintaining and developing this Software!

In my setup there was a missing dependency: xorg-xrandr

@langurmonkey, thx, i'll answered back at the github.

langurmonkey commented on 2016-09-30 18:31 (UTC)

This is the developer. This bug is weird, I use Arch in all my machines and never encountered it, nor was the issue reported from any other distro or operating system. Basically, there is a pool of vector objects to avoid memory allocation. Each frame we need to compute the RA/DEC position of hte mouse pointer. For that, a couple of vectors are requested (one contains the input screen x and y coordinates, the other is for the output RA/DEC/Distance information). As it turns out, the output vector returned by the pool is null, which is VERY strange. Can you outline what more or less in what situation the crash occurs? Is it completely random? What is the camera mode? I created a new issue in github for this here: Thanks for reporting!

The app. hangs up (always) after a while (it's random, sometime it takes longer, sometime right), but obviously with the very same "Exception in thread "LWJGL Application" java.lang.NullPointerException" failure: { java -Xms1g -Xmx2g -XX:+UseConcMarkSweepGC -cp "/opt/gaiasky/lib/*" gaia.cu9.ari.gaiaorbit.desktop.GaiaSkyDesktop GlobalConf - GUI scale factor set to 0.96946806 Loaded 1 music files Configuration saved to ~/.gaiasky/ Display mode set to 1600x1200, fullscreen: false FOV: 0.89079 19:22:25: GaiaSky - GLSL version: 4.50 NVIDIA ... ... ...
