Dear Roy,
Thank you for this info. It seems that only the versions of Xcode which
you download from the AppStore need the Command Line Tools installed.
In our experience all versions since 4.5 do, wherever you install them
from. People who use long-outdated versions of tools cannot expect the
current instructions to apply to them. And the R manual does make that
clear:
‘Command Line Tools for Xcode’ used to be part of the Apple Developer
Tools (‘Xcode’) but nowadays need to be installed separately. They can
be downloaded from http://developer.apple.com/devcenter/mac/ (you will
need to register there) or if you have a recent Xcode installed (from
the App Store or from https://developer.apple.com/devcenter/mac/) you
can install the command-line tools from within Xcode, from the
‘Downloads’ pane in the ‘Preferences’.
Note 'used', 'nowadays', 'recent'.
Nevertheless, in order to install a new version of clang I need to
install the CLTs.
And isn't it nice of Apple to allow you to download them separately?
Best regards,
Christian

My apologies, I didn't notice carefully that you were using Xcode
4.2.1. But Google is your friend, Apple has changed the name of what
you need to download, see:

HTH.

Dear Simon,
On your developer site you mention:
"We use Xcode 4.2 but Xcode 3.2 and higher should work as well.
Note that you will need Command Line Tools component of Xcode on
Mac OS X 10.7 or higher."
I am running OS X 10.7.5 and XCode 4.2.1 on my Mac, but have not
downloaded the command line tools. My questions are:
- why do I need the command line tools?
Because Xcode no longer installs compilers, linkers etc. in the
system, so you won't be able to run them.
It seems that my version of Xcode 4.2.1 does have all compilers
installed, including clang, but version 3.0:
$ clang -v
Apple clang version 3.0 (tags/Apple/clang-211.12) (based on LLVM 3.0svn)
Target: x86_64-apple-darwin11.4.2
- which version do I need to download from:
https://developer.apple.com/downloads/index.action
There are e.g.
- Command Line Tools (OS X Lion) for Xcode - October 2012
(it is not mentioned which version of Xcode)
- Command Line Tools (OS X Lion) for Xcode - November 2012
(Xcode 4.3 is mentioned but it is nor clear if it works with
4.2.1)
- Command Line Tools (OS X Lion) for Xcode - April 2013
(Xcode 4.6.2 is mentioned but it is nor clear if it works with
4.2.1)
It doesn't really matter (it may matter in the future, because Apple
has announced that they'll be removing llvm-gcc from Xcode) - latest
should be fine for now. The version is independent of your Xcode --
in fact if you download it by hand, you don't even need Xcode at all.
(BTW, the Preferences for Xcode 4.2.1 do not list Command Line
Tools in the Install window.)
I'm not sure what you mean by "Install window", but as Roy said,
you'll find it in the download section of the preferences.
When I open the Preferences and go to the download section I see a
checkbox "Check for and install updates automatically", and below the
list of items, which are:
- iOS 4.3 Simulator (499.2 MB)
- iOS 4.0 - 4.1 Device Debugging Support (505.1 MB)
- iOS 3.0 - 3.2.2 Device Debugging Support (686.3 MB)
None of these three items do I want to install since the download
would be 1.7 GB and my internet connection is not very fast.
- do the Command Line Tools update clang/clang++?
Yes
This is good news.
The reason for my question is that in order to compile the C++ code
in my package with clang I need at least version 3.1 since 3.0
results in an error.
You'll need to tweak your local ~/.R/Makevars for that to work since
CRAN's R uses llvm-gcc.
This seems not to be possible since then I cannot compile my C++ code
at all. It seems to interfere with the ROOT framework compiled with
clang and does not find an include file. My Makefile depends on the
ROOT config file.
Cheers,
Simon
