Im on Ubutnu 12.04, 64 bit and keep getting http://pastebin.com/6kyAgfDq
seeing

2013-09-08 00:07:04 [INFO] [STDERR] Caused by: java.lang.UnsatisfiedLinkError: /home/jeff/Ultimate/minecraft/bin/natives/liblwjgl.so: /home/jeff/Ultimate/minecraft/bin/natives/liblwjgl.so: wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch)

I tryed to update lwjgl as i had to for vanilla, with no luck. (vanilla works, fine)
I also tryed changeing java, so far i have tryed..
Java 7 openJDK
Java 7 Oracle
Java 6 openJDK

i also was reading about changeing your folder off the desktop, so it tried that, no luck.

Finally i seen this code
export LD_LIBRARY_PATH="/opt/java/jre/lib/amd64"
java -Xmx1024M -Xms512M -cp minecraft.jar

With even more so, no luck.

Im out of ideas on how to fix this.

are u sure u updated lwjgl correctly?
u need to copy over the library files and the jar files to the correct location in the minecraft dir.
files from 'lwjgl-2.9.0/jar' go into 'minecraft/bin'
and files from 'lwjgl-2.9.0/native/linux' go into 'minecraft/bin/native'

I get this same error on ubuntu and updating lwjgl fixes it

I got the same error, I don't know a lot about linux.

Which pack do you wish to update the lwjgl in? Unless it is pre 1.6.4 you do not need to worry about it. The 1.6.4 packs have lwjgl version 2.9.0

This guide should help. Remember that the folder you want to change is inside the mod pack folder not the vanilla install. So for every pre 1.6.4 pack you wish to use you will need to update inside each modpack folder.

Thank you soooo much, ftb launches perfectly now. I followed the tutorial in the link, and used the unleashed folder instead of the mc folder
