Oxidizer for Snow Leopard

UPDATED  Official Oxidizer updates from David Burnett have been posted in the comments, grab ’em while they’re hot!

This version comes to us courtesy of our friend ‘OnlyJedi’, here’s the scoop as quoted from this forum thread

I’ve been having the same problem on Snow Leopard (10.6.1) with both Oxidizer and 0.5.5.  Any attempt to either create a new flame or move a flame from the Gene Pool to the editor crashes Oxidizer.

So I did as David suggested and compiled Oxidizer myself (using the 0.5.5 sources, I couldn’t find anything later).  After setting the target to 10.6 & i386, everything seems to work; no editing of source code needed.  I haven’t had a chance for a more thorough test yet, but at the very least I can create new flames, move flames from the gene pool, edit and render without crashes.

I’d be willing to share my .app if anyone wants.  If I could get a hold of the sources (wink wink nudge nudge) I could probably make a 10.6 compatible version of that as well.

    I was going to try that yesterday myself, except I had no source files to build from.

    Thanks for your effort.

    As now comes the official executables :-) Snow Leopard release Snow Leopard release

    Yes I finally got my hands on a copy, and I had to ask at the shop, an Apple specialist, as they didn’t have any on display !?!

    Anyway thanks to every one who sent in a bug report and Dan aka dak180 who also pushed me along the ‘use 10.6 SDK’ line to get Oxidizer to work.

    If anyone is interested it appears to be some weird compatibility issue involving Core Data and Pop-up buttons, at least that’s is far as I got trying to get it to work with the 10.5 SDK.

    Now the big question is do these builds still work on Leopard.

    Both crash on launch in Leopard on my MacBook Pro.

    Thanks a bunch. Guess I won’t need those 1.5.x sources after all :D

    Running 10.6.1.

    Both new executables ran fine, when under the previous versions, they crashed upon loading the .flam3 document.

    The new version runs extremely fast, about twice as fast as version on my computer! :-)

    So for ignorant people like me, what’s the difference between and I assumed the former is latest and greatest, but the other stuff I’ve read seems to indicate that’s not the case…

    To put it simply is what will become version 1.0 andwill produce
    flames that are compatible with Electric Sheep 2.7. as is therefore
    targeted at those users who want to produce Sheeep for E.S. is hacked to support the flam3 variations that are not
    available in Electric Sheep 2.7 but will be in Electric Sheep 2.8 or
    whatever the next version is. This is more for the people who use Oxidizer
    to create the wonderful art you see on this blog and deviantart amongst
    other places.

    Okay so now, I’ve got to find how to build Oxidizer on Snow Leopard so that it works on Leopard and preferably still works on Snow Leopard.

    So I’m going start a few experimental releases and what I’d like some volunteers to try them on Leopard and on Snow Leopard. On both OS version I just want to know if it works unless there a major change like a big performance deficit.

    The first release is here… this should still run on Snow Leoaprd based on my own testing, the question is does it run on Leopard and is it as fast as Don reports on Snow Leopard.
    Oh, for the technically inclined this version is built with the 10.6 SDK using GCC 4.0 to compile. The Lua bridge is still built with GCC 4.2 as are the flam3 excutables so I’d guess these might not work on Leopard if Oxidizer starts up at all.

    Leopard; crash on launch…

    Ran fine on 10.6.1. About the same rendering speed for previous flam3 document, negligible difference. I don’t have a Leopard system to test.

    Dave – I’m just about to get Snow Leopard, and would be happy to put it on the MacBook and leave Leopard on the iMac and then try both. Will take a day or two for me to set up but will happily do so and let you know how I get on!

    This version of Oxidizer is build with GCC 4.0 (flam3 stuff build with GCC 4.2) through out SDK 10.5 through out.

    This will crash on Snow Leopard (tried it) so it’s a test of Leopard compatabilty and if I need to work out how to build the flam3 stuff with GCC 4.0 until I merge the code back in.
