Bundling framework in SL release build will not run on Leopard

[jtc331@…]

I have an app that has the embed macruby target include when I do a release build (Xcode is set to release for 10.5) but the generated release will only work on SL machines not Leopard machines. Neither machine tested has macruby installed. It crashes with the following error in the console:

Looks like the availability macros are not properly propagated from Xcode.

Cc Me!

Laurent, I think this is still an issue in 0.5 final.

What did you mean with "availability macros"? Anything I can fix on my end, i.e. in my Xcode?

Our framework does not support both Leopard and SnowLeopard. You can build MacRuby for Leopard or SnowLeopard. Making a version that will work on both systems is possible but is not a high priority for us, due to lack of resources.

Replying to lsansonetti@…:

Thanks for the honest answer. Oiy, that's bad for me, but hey… 0.5 and all, tight resources, I understand. :)

Is there a way for devs like me to build a combined Leopard/Snopard MR release at home? And if yes, could you please point me in the right direction (build instructions or anything else) so I can go learn about it and test my mettle?

[lsansonetti@…]

We no longer support Leopard.
