problem seems to be localized to gentoo comps in my house,  what is this error telling me? is there a specific path its trying to find the lwjgl files at? other than natives?

Eh? LWJGL is supposed to be downloaded by the launcher, but for some reason it's not found.

Follow this: http://www.minecraftwiki.net/wiki/Tutorials/Update_LWJGL

after forcing an update it starts up fine now....  that did not fix the problem before so i'm not sure why it worked this time. but i am happy it is working now....  not really solved though

For other people having this isue: You need to make all the native (the ones in ~/.minecraft/bin/native) libraries 64 bit (on 64 bit linux) or 32 bit (vice versa).

If that doesn't work, try reinstalling/updating/downgrading Java.

And if it still doesn't work, throw your monitor out the window.

hi

I'm using Minecraft official launcher. it's making symlinks to lwjgl by it's own. I can play clean MC, but if I patch it with fml, get the same error like at the topic. I've tried to download lwjgl by myself — it still doesn't work.

I've tried sun's, oracle's and icedtea's JDK but still not working

Minecraft is *not* supposed to download LWJGL or any .jar files on Gentoo. It just uses the system libraries insted of using its own.

 

Apparently that makes Forge just stand there dumbfounded not sure how to react. It seems to depend on all jars being shipped along with the game instead of being system-wide libraries.

 

/usr/games/bin/minecraft on Gentoo -- works perfectly with Vanilla, but Forge cannot compute

1) dont bump old ass threads

2) Forge doesn't care where the jars as, it doesn't touch anything related to lwjgl So if you're hacking things around, you're gunna have to figure it out.
