Vector<vector<string> >

ROOT

I am using Makeclass to create Analysis framework. I got error in using the vector<vector > and i followed the twiki page and added following before the include statements in ‘analysis .h’ file.
…
#ifdef MAKECINT
#pragma link C++ class std::vector < std::vector >+;
#pragma link C++ class std::vector < std::vector >+;
#endif

#ifndef Analysis_h
#define Analysis_h
#include <TROOT.h>
#include <TChain.h>
#include <TFile.h>
…
Still am gettting following error

Error: Invalid type ‘vector<vector’ in declaration of ‘>’ Analysis.h:133:
Error: Symbol vector<vector > is not defined in current scope Analysis.h:133:
Error: Symbol trig_L1_jet_thrNames is not defined in current scope Analysis.h:133:
*** Interpreter error recovered ***
…

Kinidly provide me a solution.

Hi,

You need to add#include <vector> #include <string>

Cheers,

Hi Philippe,

Thanks for the solution. Now the event loop runs if i add the two include statements. Along with that it creates these files in the same directory.

AutoDict_random_access_iterator_vector_string_allocator_string____long_.cxx AutoDict_vector_vector_float_allocator_float______cxx.so
AutoDict_random_access_iterator_vector_string_allocator_string____long__cxx.d AutoDict_vector_vector_string_allocator_string_____.cxx
AutoDict_vector_vector_float_allocator_float_____.cxx AutoDict_vector_vector_string_allocator_string______cxx.d
AutoDict_vector_vector_float_allocator_float______cxx.d

Is this alright? Thanks for the time you spend on this.

Hi,

Yes those are expected (they are the automatically generated dictionaries for the STL container you are using).

Cheers,
Philippe.
