clang-3.4 fails to build on Snow Leopard (succeeds upon retry)

[ryandesign (Ryan Carsten Schmidt)]

On Snow Leopard, clang-3.4 fails to build with many "can't parse dwarf compilation unit info" errors.

[jeremyhu (Jeremy Huddleston Sequoia)]

Disable parallel building or just keep retrying.

[jeremyhu (Jeremy Huddleston Sequoia)]

Im not sure why this is only impacting SL and earlier.

log without parallel building

[ryandesign (Ryan Carsten Schmidt)]

Disabling parallel building does not result in a successful build. I've attached a new log.

[jeremyhu (Jeremy Huddleston Sequoia)]

Hrm... well suggestions are welcomed. I got it to build by retrying a few times =(

Does r117563 address this for you?

clang-3.4 still does not build for me on OS X 10.6.8. I've attached the build log.

[jeremyhu (Jeremy Huddleston Sequoia)]

Please attach your log after updating to r117573

Does llvm-3.5 build for you? I experienced no issues with clang-3.5 on my SL machine.

Unfortunately, the SL buildbot is down right now.

llvm-3.5 build log, OS X 10.6.8

[mopihopi]

llvm-3.5 does not build either:
:error:fetch llvm-3.5 requires a C++11 runtime, which your configuration does not allow

Full log is attached.

(clang-3.4 is still building.)

If you want to use it, you can install libcxx and then choose libc++ as your C++ runtime in macports.conf. It'll require a rebuild of all your C++ ports.

[jeremyhu (Jeremy Huddleston Sequoia)]

Actually, llvm-3.5's build should "just work" if you're on trunk base.

I do have libcxx installed. It installed them when I attempted to install llvm-3.5:

You need trunk base too

Great.
