clang-3.7 @3.7-r232656_0: libcompiler_rt.dylib: No such file or directory

While trying to upgrade clang-3.7 from 3.7-r231583_0 to 3.7-r232656_0 I on Snow Leopard 10.6.8 receive the following error:

libcompiler_rt.dylib is not existing, while libcompiler_rt.a apparently is? Is libcompiler_rt.dylib really required?

[udbraumann]

FWIW: since I noticed that r234122_0 came out in between, I tried to upgrade to this particular release candidate, however, there is some confusion while applying patches:

See main-r234122_0.log.

Inside clang_darwin.mk.rej I find this:

***************

  # Darwin 10.6 has a bug in cctools that makes it unable to use ranlib on our ARM

Thanks for your help.

Sorry, that's a conditional patch for older systems, so I forgot to test it. I'll regenerate it.

[udbraumann]

Thanks for fixing the trouble with the patches in 3.7-r234122_0.

Have tested clang-3.7 r235803_0 but the problem with the missing libcompiler_rt.dylib which firstly occurred in r232656_0 still is there.

[h.rayflood@…]

#47729 maybe resolve this probrem.

[h.rayflood@…]

Cc Me!

I am sorry to report that r138590 unfortunately does not fix the problem for my 10.6.8 platform with Xcode 4.2:

Please see the full log in main-r241984.log.gz

[jeremyhu (Jeremy Huddleston Sequoia)]

Well please open another ticket with for your case. I don't see how that could possibly be happening given the Makefile doesn't add the ubsan_iossim_dynamic config any more.
