Unix Launcher won't launch.

[creativetux]

Fresh Ubuntu 12.10, with Sun Java 8 from ppa and latest nvidia drivers from ppa.

java -jar FTB_Launcher.jar results in:

In the launcher window:

Also the copy to pastebin doesn't work and resulted in:

Java 8? I think you need java 7. From reading the report I think you should try it.

 

[creativetux]

Thats a bit crap. Minecraft works no problems on Java 8!

Yes, but does the launcher?

CreativeTux can install OpenJDK_7 alongside and switch with sudo update-alternatives --config java

(Note: I run squeeze, not ubuntu, but I assume it's the same.)

 

[frederikam]

The launcher and Minecraft is 2 different things.

 

[creativetux]

Minecraft doesn't perform well with OpenJDK, hencing having Oracle on my system from the PPA. I wrote some Java to launch the FTB launcher faking it into thinking its Java 7. Working like a charm now.

 

[Sal]

I've been running with OpenJDK for quite a while now with only minor hitches. Right now I'm running FTB and thus minecraft through v7. Might want to give it a try, depending on how foss you are. =)

Nice to hear that you got your problem solved.

 

[creativetux]

Yeah, if you use Oracle Java 7 on Ubuntu 64bit 12.10 it complains about lwjgl being the wrong ELF class, so you have to use Java 8 for Minecraft. If you have sticky keys, then you'll need to update the lwjgl within the jar file. I wrote a post on my blog about it. The launcher really needs fixing for others tho.

 

[Sal]

LOL, Thanks! I think you just answered Etopsirhc's problem!

 

[creativetux]

Yep Update the launcher haha

 

[Binarin]

So the error only occurred because you had Java 8?
I had the same error with Java 7 on Windows

[etopsirhc]

so the problem with the wrong elfclass is just update to java 8? or was it somthing the launcher needed to fix ? *slightly lost*
currently running java7-64 and when i get the wrong elfclass error i copy over a new set of lwjgl jar files and their natives to the bin folder. only really happens on new installs or forced updates to the modpack ( witch is just a fresh install in itself )
