Dear all, I have installed ROOT with flags
./configure macosx64 --prefix=/usr/local/root/
make -j 4
sudo make install
And I do not see any TMVA folder in $ROOTSYS, do you know why this is?
Thanks.

Dear leoredi,
TMVA should be build by default.
It should install libTMVA.so under /usr/local/root/lib .
What do you mean exactly by ‘no TMVA folder in $ROOTSYS’ ?
What is $ROOTSYS in your case?
Can you post the output of the ‘configure’ step?
G Ganis
Thanks for the reply.
So yes I have the libraries:
Then the problem must be with TMVA itself, not with the installation of root, let me explain.
Following what is written here: http://tmva.sourceforge.net/docu/TMVAUsersGuide.pdf on page 4 I:
download TMVA "tar-ball" from https://sourceforge.net/projects/tmva/files/
~> tar -zxvf TMVA-v4.2.0.tgz
~> cd TMVA-v4.2.0
~/TMVA-v4.2.0> make
And I get what you see at the end of this message. Could this be because of the way I have installed ROOT? I do not have the configure step output but everything worked like a charm so far,

Hi,
You should try to avoid , i possible, to install your version of TMVA. I would recommend to use directly the one coming from ROOT. So, ignore these lines in the manual. These are vlid if you are using a very old version of ROOT and you need a newer TMVA version.
Best Regards
Lorenzo
Dear all,
Following Lorenzo’s suggestion I am now using ROOT directly.
I have installed ROOT v6.05.02 using
Now have you got any idea how can I see if it actually works as expected?
If I download TMVA.tar and move into /test/ and try to run
I get a lot of errors even if the application finishes, the logs are:

Hi,
Why are you still downloading TMVA ?
Everything is within ROOT , if you take TMVAClassification.C from somewhere else, you might have an old version.
To see if it is working, just go to $ROOTSYS/tutorials/tmva and do:
root TMVAClassification.C
Lorenzo
I don’t have any tutorial folder in my $ROOTSYS.
If I do echo $ROOTSYS I get /usr/local/root then I do ll $ROOTSYS I get
drwxr-xr-x 3 root admin 102B 24 Sep 18:13 lib/
drwxr-xr-x 3 root admin 102B 24 Sep 18:13 include/

drwxr-xr-x 3 root admin 102B 24 Sep 18:13 etc/
drwxr-xr-x 7 root admin 238B 24 Sep 18:13 share/
Is it because of how I have installed it? Which was:
* Download binary
* cd into folder after unzip
* ./configure macosx64 --prefix=/usr/local/root/ -all
* make -j 4
* sudo make install
* vim .profile with `. /usr/local/root/bin/thisroot.sh`
Thanks.
HI,
You have probably installed somewhere else the tutorials (something like a doc directory).
To know it where they are just print in the root prompt the value of
gROOT->GetTutorialsDir()
