I typed
(adding -mp- for each compiler because of the MacPorts download) and this solved!!! So the first part (configure) has been completed and now i’m waiting for the make command to reach the end of the process.
Thank you so so so so so so so so so much!!! 
You are welcome 
Note that if you have eg. 4 cores you can speedup the make process with
make -j4Thank you so much!!!
I’m here again 
After ~45 mins of processes i got this:

Do you know how to solve this issue?
Thanks again
I am not sure, but there is recent bug fix with Cocoa and Mac, see
root.cern.ch/gitweb/?p=root.git … 54beb7e56b
So, I would remove everything, do “git pull” again and try with the master branch (instead of checkout 6-06-08).
If it still fails, submit a bug report:
root.cern.ch/bugs
I’ll try with this, thanks again!!
I’m sorry, i don’t want to make errors 
I erased everything and i typed
git clone http://root.cern.ch/git/root.git
cd root
git pull
git tag -l
Now what i should do instead of
git checkout -b v6-04-02 v6-04-02 ?
Don’t type anything after “git clone”. The default behaviour is to be on the master branch (the latest version). To check this, just do:
cd root
git statusAnd it should tell you that you are in the master branch.
In summary:
cd /opt/
git clone http://root.cern.ch/git/root.git root
mkdir root_build
cd root_build
unset LIBRARY_PATH CPATH C_INCLUDE_PATH PKG_CONFIG_PATH CPLUS_INCLUDE_PATH INCLUDE
export PATH=/opt/local/bin:$PATH

make -j4Yes, you’re right, i got it:

[15:04:59 root_build ]> sudo make -j4Maybe Clang 3.9.0 is too old or maybe the issues come from the failed tests at the end
Could be a good idea to install Root with this?
sudo port install root Can you type “make” instead of “make -j4”? Maybe we can see then a clearer error message.
Clang version should be enough. Did you check this?
root.cern.ch/build-prerequisites
Maybe, it is related to this bug:
And you can try to use a bash shell instead of fish shell?
Hello:
I downloaded the latest version of ROOT, then:
Opened the Xcode project and built from inside. Everything was built smoothly that way.
Using cmake produced lot of failures.
Update:
I reinstalled Xcode using the command line:
then
cmake ../root-6.06.08-source
cmake --build . --target intall
And ROOT compiled and runs on macOS Sierra 10.12
This thread was extremely helpful to me, I was having a similar issue to the OP.
I am only posting because there was a slight erratum in the instructions given upthread, the cmake invocation should be:
Rather than
which is a directory that does not actually exist.
No, cmake …/root is correct, assuming that this is the path of the source code and your build directory is /opt/root_build.
cd /opt/
git clone http://root.cern.ch/git/root.git
--> Clones the source code to /opt/root
mkdir root_build
cd root_build
--> You enter the build directory /opt/root_build
cmake ../root
--> You point at where the source code is. Alternatively:
cmake /opt/rootNote that it is recommended that source code and build directory are separated. Thus, you do not call mkdir root_build inside /opt/root/ but in /opt/
Ah, I misunderstood, I thought root_build was intended to be created as a subdirectory of root.
Hi everybody, I apologize for my late reply.
I absolutely needed Root from the beginning of this week, so I used MacPorts and everything went fine.
The instructions given by ferhue are correct, my problem was that I previously installed an old Root version (it was March 2016) and I probably deleted something important for the compiler while erasing this old version.
Thanks a lot for your help and I hope this discussion will be helpful.
Nice to hear!
Please remember to “mark as solved” (green tick).
Hello Experts,
I think this thread has been marked as solved but I would really appreciate if some can help me in fixing some problems with installing ROOT6 on Max OS Sierra 10.12. I have the following steps:
-- git clone http://root.cern.ch/git/root.git root6_src
-- mkdir root_build
-- cd build_root
-- cmake ../root6_src/ -DCMAKE_INSTALL_PREFIX=/usr/local/root -DPYTHON_EXECUTABLE=/opt/local/bin/python -DPYTHON_INCLUDE_DIR=/opt/local/Library/Frameworks/Python.framework/Versions/3.4/Headers -DPYTHON_LIBRARY=/opt/local/Library/Frameworks/Python.framework/Versions/3.4/lib/libpython3.4.dylib -Droofit=ON -Dtmva=ON -Dminuit2=ON -Dpython=ON -Dcocoa=ON
-- cmake --build . --target install

Hello Again,
Sorry for the noise: I just realized that I was not changing the python path from python-2 to python-3. Fixing the PYTHONPATH fixes every thing.
#export PYTHONPATH="/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages"
export PYTHONPATH="/opt/local/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages"
Hi,
I haven’t tried Brew yet, but I can confirm you that the ROOT installation with MacPorts works fine.
