The default compiler on 10.6 does not support C++11. Blacklisting the default compiler in favor of a newer version of clang may help.

[neverpanic (Clemens Lang)]

No, that won't help. C++11 isn't happening on Snow Leopard unless you jump through lots of hoops. The LibcxxOnOlderSystems wiki page has more information.

We'll likely have to declare encfs as unsupported on any platform that doesn't support C++11.

[dbevans (David B. Evans)]

That's what I was wondering. The build also fails on 10.8 as one might expect and surely 10.7 as well. A candidate for the cxx11 port group.

[dbevans (David B. Evans)]

Closing as won't (really can't fix) due to the requirement for full C++11 support. This limits the build to 10.9+ only. cxx11 port group added in r144992.
