llvm dev - Jun 2016 - Unable to build and install LLVM on Mac OSX 10.11

Greetings dear developers!!

I've been faced with several difficulties yet I'm unable to do a
complete
build of LLVM on my system.

I've tried to build with Xcode once, ninja + cmake, and several other ways
as shown in the web.

Currently, while building on Xcode for the umpteenth time I got an error
which says outdated version of svn being used and then architecture not
supported.

When using ninja or make to complete the install, it ends with prompt
saying that it ended in a fatal error and the header file  <stdio.h>
couldn't be found.

I've tried building the same several times.

I've 4gb ram with an i5 processor and running the latest OSX on my
macintosh.

I've tried most of the solutions stated in the web.

Can anyone help me with regarding the same. with a detailed instruction set
as to how to go about getting the build complete properly.

Thank you.

Yours sincerely,
Sumedh Arani.

Hi,

Building on OS X with Xcode is well tested: http://lab.llvm.org:8080/green/

What does `xcrun clang -v` returns on your system?
What is your cmake command line?

Starting simple I'd expect this sequence of command to work:

git clone http://llvm.org/git/llvm.git 
mkdir build
cd build
xcrun cmake ../llvm
make

If this does not work, please post more information on what failure do you see.

Another good way to reproduce the tested configuration is to look at the log on
the bots and use the same cmake args:

Arani:~ Sumedh$ xcrun clang -v

Apple LLVM version 7.3.0 (clang-703.0.31)

Target: x86_64-apple-darwin15.4.0

Thread model: posix

InstalledDir:
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin



Greetings!!


I followed the instructions given by you to the letter and it worked like a
charm.


Just this time I didn't download compiler-rt or any other extra tools.


How can I upgrade to them??


And also how can I change my version of clang to the one which has been
built now? As on doing clang --version or xcrun clang -v still gives the
version as the one that comes pre built with apple's machine.


Thank you.


Yours sincerely,

Sumedh Arani.
