I know but I'm working with 64 bits software and I don't want to invest time in recompiling/back porting to 32 bits. I'm not stuck cause I have an Ubuntu VM but this is not as nice as developing directly on Mac OS.
There is a 64 bit version in the download area but it just does not work. Can Oracle fix it? There are probably a number of Mac developers who would be happy to have a 64 bit version that works.
Not sure which download page you are referring to, but as I see the latest version is 10.2.0.4 for Mac OS X (intel) and requirements for that version clearly state "Apple Mac OS X Server 10.5.4". No claims it should work on Lion, so why claim it is "broken".
Or are you really complaining that Oracle should support current Mac OS as a platform?
Perhaps running a virtual host with a platform currently supported could serve as a workaround.
This thread refers to Oracle Instant Client (downloadable here: http://www.oracle.com/technetwork/topics/intel-macsoft-096467.html, which is one level down from the page to which you so helpfully link) being broken with Mac OS X Lion.
This thread is not about Oracle server not working on Lion.
Yes, Oracle really should support the current version of Mac OS X as a full featured 64 bit client.
Running an Oracle server on a virtual host will not fix the problem if you don't have a client on the native host to get there.
According to the Oracle database release schedule (viewable through metalink if you've got a support account), there will be an 18.104.22.168 instantclient for Intel Mac available sometime during the first quarter of 2012 (ie any time now, hopefully).
