I'm getting some pretty nice Java exceptions thrown at me when I try to run the Illarion client on my brand new (Intel) MacBook Pro. I am indeed running OS X 10.4.7, and I have not done anything to my Java installation.

I can start Illarion up and get the login screen. I bang in my login credentials, set some options, and try to login. That gives me a big, beautiful exception.

Ouch. Initially, I thought I'd gotten a corrupt version of some library that gets pulled down when Javaws installs Illarion. However, Vilarion told me to try running the test from LJWGL's website.

As you see, it starts off pretty well, printing some help to the terminal. Then it goes to draw a window...and BAM. Not so much.

This forum post seems to mention my issue, and suggest fixes, but I don't speak durkadurka javastani, so I'm having a hard time figuring out if there's a fix I can do or if I need to wait for a new client relase, OR if I need to wait for a proper fix in the library before I can get it running on OS X.

So. Uh. Where do I go from here? I'd love to get rid of some hardware, but I can't start selling it off until Illarion will work for me. =/

And of course, thanks for your time reading my ramblings.

I tried running the tests on the installation page of the lwjgl website with the most recent release (1.0beta3). It still didn't run. (I believe I tested with 1.0beta2 last time).

        at org.lwjgl.test.WindowCreationTest.main(WindowCreationTest.java:284)

I did a little bit of reading, and then modified the test comand, like so:

Code: Select all

java -cp .:res:jar/lwjgl.jar:jar/lwjgl_test.jar:jar/lwjgl_util.jar:jar/lwjgl_fmod3.jar:jar/lwjgl_devil.jar:jar/jinput.jar:     -Djava.library.path=native/[b]macosx/[/b] org.lwjgl.test.WindowCreationTest

Note the ephasized addition to the library path. This brought up a flashing window.

So it looks like the library (at least 1.0beta3) does in fact work on Intel Macs.

Sooo...why is the Illarion client not working? :>

Wait for Nop to pop up, he'll likely be able to help.
He doesn't visit the forums all to much.

I pulled open one of those .jar files to see what's actually going on. I did find something that I *think* may be causing the problem.

Code: Select all

172:~/Library/Caches/Java/cache/javaws/http/Ddownload.illarion.org/P80/DMlib_mac nevans$ file liblwjgl.jnilib 
liblwjgl.jnilib: Mach-O dynamically linked shared library ppc

The version of liblwjgl that came with Illarion does not look like its a universal binary. Of course, I don't know that there's no other version of the file in one of the jars that I didn't touch. I'm not a Java guy by any means, and I know embarassingly little about how it all goes together.

I found a file named smilarly in the native/macosx folder in the lwjgl 1.0beta3 download, and found that it is a universal binary.

Code: Select all

172:~/Desktop/lwjgl-1.0beta3/native/macosx nevans$ file liblwjgl.jnilib
liblwjgl.jnilib: Mach-O universal binary with 2 architectures
liblwjgl.jnilib (for architecture ppc): Mach-O dynamically linked shared library ppc
liblwjgl.jnilib (for architecture i386):        Mach-O dynamically linked shared library i386

Unfortunately, I saw what looked to be an rsa key, so I'm guessing the files are signed. So even if I knew how to repackage the 1.0beta3 files into .jars, and by some miracle they would work dropped-in like that, Javaws probably wouldn't run the hacked up Illarion client.

So I think I'm dead-ended.

I guess you are right - the version of the library is most likely obsolete.

Since none of us here in the dev team is a mac user I added the mac files, hoping the best, but they were never updated. I can try adding the latest version from lwjgl to the client instead of the current libs that are almost one year old.

First and foremost, thank you for looking at my problem.

I would be more than happy to test the changes out if you want me to.

Posted: **Fri Sep 08, 2006 12:28 am**

Just posting to say that the changes made in the new client release are working for me.

I have not done any extensive play testing, but I don't envision any troubles.

Thank you very much, Nop. =D
