That seems to work for libc++. However, the problem persists when building an XCode project on 10.6:
| clang: error: invalid deployment target for -stdlib=libc++ (requires Mac OS X 10.7 or later)
When I change the build variable MACOSX_DEPLOYMENT_TARGET to 10.7, the project builds, but of course crashes on
The TOT from last week worked perfectly. Is there a non-political (i.e. not Apple wanting people to ditch 10.6)
reason for this change?
Thanks in advance,
