Installing ROOT 6 on Mac Pro

ROOT
1

I am installing a new version of ROOT 6.06 on my recently upgraded Mac Pro.
I downloaded Xcode and CMake.

Now when try to run . /bootstrap in the CMake 3.8.1 directory, I get the following errors. I am not an expert and somehow can not figure out what to do next!. So need help.

Tell CMake where to find the compiler by setting either the environment
variable “CC” or the CMake cache entry CMAKE_C_COMPILER to the full path to
the compiler, or to the compiler name if it is in the PATH.

Hello,

I am not sure this is the right forum for this, being most likely an issue with CMake and/or XCode rather then ROOT.
Did you try by googling?

I am trying. Yes, you are right.

This looks like an issue with Xcode. Can you post the path from:

xcode-select --print-path

Most likely the command line tools are not installed and you need to do the following

xcode-select --install

Hello

xcode-select --print-path gives
/Applications/Xcode.app/Contents/Developer

and

xcode-select --install
xcode-select: error: command line tools are already installed, use “Software Update” to install updates.

which I did.

Then I tried to build root from
cmake build

It took almost 4 hours and with several warnings, it ended with following error message;

waiting to hear for some solution.

What do you mean here? Are you followiing these directions?

Did you make fresh build directory after updating xcode?

Yes, I downloaded a version of ROOT 6.04 and made a fresh build directory.
