Root v6.10/02 installation, tmva tutorial problem

[cvarni]

Dear Experts,
quite some time ago I posted my problems (now solved) during the installation of Root v6.

Problems during Build and Install of Root v6.10/02

Dear experts, I’m trying to install Root v6.10/02 (downloaded by the git repository) on macOs Sierra 10.12.6, but I have several problems in doing so. I have successfully downloaded Root, checked out the right branch, created a Build Directory and started the compilation. This is exactly what I’m doing in the “/usr/local/” folder (and with “sudo”): <download root and move to /usr/local/> cd root git checkout -b v6-10-02 v6-10-02 mkdir BuildDir cd BuildDir cmake ../ -Dgnuinstall=ON -Dsoversion…

I only want to report here that when compiling the TMVA tutorial I’ve encountered once again the problem with TMVAClassification.C, TMVAClassificationApplication.C, TMVARegression.C, TMVARegressionApplication.C, TMVAMulticlass.C, TMVAMulticlassApplication.C.

TMVAClassification.C:148:22: error: call to constructor of 'std::string' (aka
      'basic_string<char, char_traits<char>, allocator<char> >') is ambiguous
         std::string regMethod(mlist[i]);

I have manually solved the problem adding a .Data() after mlist[i].
They are not pivotal files for the root installation, but maybe it is worth fixing this issue.

Thanks,
Carlo

Hi Carlo,
I guess this is on mac with XCode 9.
These incompatibilities should be solved in v6.10/8 (released 2 days ago) and in master.

Let us know if this is not the case.
Cheers,
Enrico
