Mac - Is it worth it?

[dmoc]

Looking through the forums it appears there are several unresolved (unresolve-able?) issues with getting lwjgl working fully on the Mac. If the aim is for x-platform development would C & SDL be a better bet? LWJGL looks a great project but I'm keen to avoid investing too much time in it if I can't get the degree of platform independence I'm looking for. Please note this is not intended as a criticism of LWJGL (maybe of Apple) as I realise there's no definate delivery dates in projects of this type (hell, some die out before even getting started!). I do hope the Mac issues can be sorted out because I think this will benefit LWJGL.

Er, there are no issues as far as I'm aware... although we don't have the latest FMOD and DevIL bits compiled, the core LWJGL stuff is all perfectly kosher. Apple have even fixed loads of stuff in 10.4 that we had to workaround which is nice.

Hi Cas. I'm on 10.3.9 with no intention of upgrading in the near future. I've been trying on/off for a couple of day's and although I get some stuff working most things fall over. I think locating the resources is the main issue.

Any specific problems running games or is it problems developing?

I'm off to bed now but will post the results of the tests tomorrow. Thanks for replying.

Here's a few examples of the problems I'm having.

With the contents of "jar" and "native" copied to "~/Library/Java/Extensions" and with "lwjgl-macosx-0.96" as the current directory (original "jar" and "native" directories still present)...

org.lwjgl.test.devil.BasicTest
==============================

Tried...

java org.lwjgl.test.devil.BasicTest
java -Djava.library.path=native org.lwjgl.test.devil.BasicTest
java -cp ./jar:./res -Djava.library.path=native org.lwjgl.test.devil.BasicTest
java -cp ./jar:./res -Djava.library.path=native org.lwjgl.test.devil.BasicTest
java -cp ./jar:./res -Djava.library.path=./native org.lwjgl.test.devil.BasicTest
java -cp .:./jar:./res -Djava.library.path=./native org.lwjgl.test.devil.BasicTest

All result in...
