[SOLVED] Installing Java 7

sycamorex · 08-01-2012, 02:17 AM

Just an update for people playing minecraft on Slackware-current.

Having installed Oracle's jre using the newly added slackbuilds in /extra/source, I had problems running Minecraft. First it complained about the architecture mismatch. Then I exported:

Code:

export LD_LIBRARY_PATH="/usr/lib64/jvm/jre/lib/amd64"

and I got:

Code:

 A fatal error has been detected by the Java Runtime Environment:
#
#  SIGSEGV (0xb) at pc=0x00007f783e59c8cb, pid=17752, tid=140154004268800
#
# JRE version: 7.0_05-b06
# Java VM: Java HotSpot(TM) 64-Bit Server VM (23.1-b03 mixed mode linux-amd64 compressed oops)
# Problematic frame:
# V  [libjvm.so+0x5668cb]  jni_GetLongField+0x9b
#
# Failed to write core dump. Core dumps have been disabled. To enable core dumping, try "ulimit -c unlimited" before starting Java again

Finally, I built minecraft with Eric's SlackBuilds and it works fine.

The package will then take care of basic environment variables and symlinks, and keep your system clean (and your package DB in sync).

If you hit any snags, perhaps someone with a 64 bit box can chime in here - but it should be pretty simple.

Hats off to that man! I'm running Slackware64 13.37 and have tried everything I could think of and what Google could provide me with in the way of possible solutions. After days of banging my head against a wall with this annoying bloody java issue I finally came across this thread earlier today.

After reading your post, astrogeek, it was indeed very simple. Embaressingly simple in fact. Though I have to admit, in my case it was not being able to see the wood for the trees. (a.k.a being a noob) :>

I checked just out of interest to make sure jre was not installed... and it was!!! So, I removed the jre and jdk packages (I really do _not_ know how jre got on there in the first place!) and installed the jdk once again. Hey presto... as if by magic, it's all working!

Code:

user@server:/# java -version
java version "1.7.0_05-icedtea"
OpenJDK Runtime Environment (IcedTea7 2.2.1) (Slackware)
OpenJDK 64-Bit Server VM (build 23.0-b21, mixed mode)

Thanks astrogeek for that "wake-me-up-i'm-being-an-idiot" slap in the face. Never again will I forget to check if jre is installed first.

The JRE would have been installed if you did a full installation of Slackware 13.37 for instance.
