The patch in question: https://www.mail-archive.com/[email protected]/msg93807.html
I'll try to find some time to take a look more closely at this, but just looking at the log I'd say it needs some modification because it doesn't provide anything for libc++abi. It also (as the OP guessed) won't work on Darwin (doesn't have libsupc++ or libstdc++). - Dan On Wed, Aug 6, 2014 at 2:59 AM, İsmail Dönmez <[email protected]> wrote: > Hi, > > Would be nice to get this reviewed.
