Cannot build 0.2.2 on os x 1.6.8

[askholme]

Tried to installed 0.2.2 on OS X 10.6.8, however the build is failing due to lack of CommonKeyDeriviation.h. As far as i gather this file is not part of the OS X crypto lib before version 10.8

Is there a strong dependency or would it be possible to build without CommonKeyDeriviation.h? (i.e. do you simply not support OS X versions earlier than 10.8)

See build output below

I managed to build purely against the openssl bindings by changing the is_available function on commoncrypto api so it specifically checks for this header file (kind of a crude hack).

That does the job for me, but it would still be nice if snow leopard was supported. It's not completly phased out yet :-)

[reaperhulk]

The CC backend is supported only in 10.8+, so your workaround was a good one. @Ayrx has put in a PR to make the CC backend more selective, and once he adds some tests to it we can merge to fix this issue.

On a separate note, be aware that 10.6 is no longer under maintenance (even security releases) from Apple so you should definitely consider moving to a newer release if your hardware supports it.

[askholme]

Thanks for confirming. I know that 10.6 is old, but one machine is a pure 32-bit 2006 mac mini which cannot go further (and a 2009 MBP doesn't perform to well under 10.7 either)

Should probably just get some new hardware instead :-)

Could always try booting linux on it! :)
