Julia failed to build on 10.6.8

[anemator]

The error looks to be a result of a dependency on c++11, which isn't bundled with 10.6.8. Any thoughts? Thanks!

Your Xcode is quite old, version 3.2.6. Is there any possibility you could update (Homebrew seems to think that 4.2 is the latest supported on 10.6) or at least install a newer version of the command line tools? 3.2.6 uses clang version 1.7, which as you surmised doesn't do well with c++11.

Most Homebrew software is going to expect a compiler newer than what you have; I highly recommend updating.

It's still officially supported along with 3.1.4 (for now at least). It looks like the issue is related to libunwind more so than your formula since I tried building outside of homebrew and saw the same

error: unrecognized command line option "-std=c++11"

Sorry about that. Thanks for your help (and yes I will be upgrading in the very near future).

Ah, I may be able to fix this then. This is because libosxunwind doesn't grab the same CFLAGS as the rest of the Julia build.

[anemator]

I think libuwind.cxx will need to be modified first. There is at least one c++11 feature used: static_assert.

libosxunwind doesn't even work on 10.6 apparently: https://groups.google.com/d/topic/julia-dev/scssTZruw9o/discussion

There is a workaround, but I don't think it's worth the effort for such a niche request: create a patch to revert back to pre-libosxunwind and apply it to Julia iff the computer doesn't have a c++11 compiler.
