Error While launching a game i am working on using LWJGL

[meriley]

I am coding using the following:
IDE: Eclipse
OS: OSX Darwin Leopard 10.5.8
Processor Architecture: 32 Bit
Java JDK: Soylatte JDK 1.6

I have verified that the native library is being referenced appropriately for LWJGL

The Error I am getting when executing code:

Exception in thread "main" java.lang.UnsatisfiedLinkError: org.lwjgl.DefaultSysImplementation.getPointerSize()I
	at org.lwjgl.DefaultSysImplementation.getPointerSize(Native Method)
	at org.lwjgl.Sys.<clinit>(Sys.java:100)

	at rts.core.Game.launch(Game.java:126)
	at rts.Launch.main(Launch.java:20)

If i use the JDK: openJDK6 then I get the error:

which version of LWJGL are you using? if your using the one that comes by default with Slick2D then that is too old, you need to use the latest version, LWJGL 2.7.1 as it has support for Darwin.

[meriley]

I have updated to the latest version of lwjgl and updated my native files and the two errors above are gone.

I have a new issue though!

Then after updating slick

This appears to be a slick issue so i dont expect an answer since this is outside of LWJGL; but i figured it throw it out there.

Using Soylatte JDK, i have not tried openJDK. These chain of errors are very strange because i cannot replicate any of these errors on my windows PC.

[kappa]

are you creating a pixel format supported by your computer?

Do you have opengl acceleration on the computer? If you don't, try running with the following VM parameter

-Dorg.lwjgl.opengl.Display.allowSoftwareOpenGL=true

If software mode works, its likely your missing opengl drivers or hardware acceleration on the computer.

[meriley]

With that VM argument I do get a bit further. X11 Starts up then program terminates.

I may have to download XCode if you think its a problem with openGL. If i remember correctly you get the openGL headers from that. Not sure if that matters necessarily.

Sadly I am still stuck with this last error on the mac OS. Tried a few things such and lowering the resolution of the game with no resolve.

Any suggestions?
