Hi all

I have struggled with backward compatability for some time and without any solution. Only way so far I have found is what Graeme describes. Compile on Mac Os 10.4 then it works on 10.5. If anybody has a better solution please let me know. Perhaps gcc 4.5 will sort it out but it is still in alpha release state (AFAIK)

regards
Garib

Hi John,

As a general point, this is a problem with Apple, which really started with the original Leopard release after Tiger was mainstream - if you compile on there it won't work on earlier releases (esp. fink compilers) however if you buy a mac you always get the latest OS X, no downgrade option. I suspect right now the street value of a PPC mac mini with tiger on it is pretty good, for exactly this reason...

If however anyone knows how to make backwards compatible binaries e.g. from Leopard to Tiger, I'm all ears.

Best,

Graeme

I guess sometimes its not worth instantly upgrading to the bleeding edge versions of software until all the major bugs have been sorted...

"Snow Leopard wiping home directory after guest log-in?"

Please can the developers keep backwards compatibility with a recent version of operating systems not just the latest release.

Thanks
