Fails with yosemite unless CC=clang

[timuckun]

I found that hint elsewhere but I could not build ruby without setting that on yosemite

I think I've been hit by the same (or at least a similar) issue. When running ruby-install ruby 2.1.4 on Yosemite, I receive the following error:

!!! Configuration of ruby 2.1.4 failed!

Yes it's the same issue. Just do this

CC=clang ruby-install .....

Yosemite has the LLVM version of gcc.

Thanks!

I'm having a similar issue when I try to install rubinius 2.3.0.

When I run CC=clang ruby-install rbx 2.3.0 it fails with this:

>>> Configuring rubinius 2.3.0 ...
Checking clang: found
Checking g++: found
Checking bison: found

Detected old configuration settings, forcing a clean build
  Checking for 'llvm-config': not found
ABORT: unable to set up LLVM

Running 'configure' failed. Please check configure.log for more details.
!!! Configuration of rbx 2.3.0 failed!

I couldn't find the configure.log mentioned, or I would post it. Any ideas what could be wrong here?

[postmodern]

@willcosgrove that's a rubinius/LLVM issue. Could you open a separate issue for your failure. configure.log should be in ~/src/rubinius-2.3.0/....

CC=clang by itself doesn't seem to resolve this with MacPorts. The following worked for me with Yosemite and MacPorts, though:

CC=clang ruby-install rbx 2.4.1 -- --llvm-config /opt/local/bin/llvm-config-mp-3.3

Your mileage may vary.

@timuckun Are you still having issues with this? I have made changes to RBX upstream that should have resolved this. Please advise whether you're still having issues, or whether this ticket can be closed. Thanks!
