[cfe-dev] Building libc++ on Lion

[Jean-Daniel Dupas]

Sorry, I missed the part of you question stating you "grabbed the abi header and dylib".
To make it clear, this step is not required on 10.7, as Lion already provide this library and the corresponding header.

I'm not hugely familiar with all of these compiler options, so before I start investigating, I was wondering if this is something people have been running into. I've only been subscribed to the mailing list for a couple weeks, so I apologize if this is a worn out topic--my attempts at google searches have not turned up anything.
