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