64-Bit on Lion? #1

Closed jsnyder closed 12 years ago

Hi -

I noticed that the builds were for 32-bit only. Is it possible to build this for 64-bit as on Lion?

Hello,

I have only a 32-bit system and Snow Leopard, but I'll see if it is possible.

After updating header locations a bit for 4.3.2 (which now keeps everything in XCode.app, at least it seems for perhaps for pre-10.7 versions), it threw some complaints about function calls having an incorrect number of parameters. I stopped there, wondering about whether I should investigate maybe newer versions of the driver you started with, but I couldn't quite figure out what sources you started with from Apple's Open Source site or what modifications might have been necessary to make this work.

Thanks in advance. I'll be happy to test and/or provide feedback if you discover a way to get things going on 64-bit (which is now the default on Lion).

On the front of your own testing, unless you have one of the earliest Core 2 Duo parts you should be able to boot into 64-bit mode (if you're interested and/or want to test things): http://support.apple.com/kb/HT3773

Best.

Please compile the new version or try SATSMARTDriver-0.2.dmg. It should have both 32-bit and 64-bit binaries compiled it.

I started with VendorSpecificType00 example and ATA driver sources. Some ATA classes are almost direct copies , like IOSATCommand <-> IOATACommand.

I have quite old Mac Mini and it does not support 64-bit mode.

The actual smart data reading was broken. Version 0.4 should work now.
