I had a program which ran great interactively. Now I have compiled it so that I can run the program non interactively on the high performance processing center at my university.There are all kinds of issues, so I made this test code to pinpoint the problems and work through them. I have tried a few versions of this code.
Upon running ./test > LOG0 I get the following error.
terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc
Aborted–LOG0–
acarnes@r14a-s31:testcode$ cat LOG0

#include <sstream>

{
std::cout << "starting test program" << std::endl;
std::cout << "creating new Tstring" << std::endl;
TString filename("test.root");
std::cout << "new TString created." << std::endl;
std::cout << "creating TFile with c_str in constructor" << std::endl;
TFile* file = new TFile("blah.root", "RECREATE");
std::cout << "TFile with c_str in constructor has been created" << std::endl;
std::cout << "creating TMVA::Factory" << std::endl;
// Load TMVA Library
TMVA::Tools::Instance();
//TString weightname("weightname");
//TString options("!V:!Silent:Color:DrawProgressBar:Transformations=I;D;P;G,D:AnalysisType=Classification");
TMVA::Factory* factory = new TMVA::Factory("weightname", file,"!V:!Silent:Color:DrawProgressBar:Transformations=I;D;P;G,D:AnalysisType=Classification" );
//clean up
delete factory;
file->Close();
std::cout << "TMVA::Factory created";
return 0;
} Then I tried to rewrite the code. Upon running version 2 below. I received the following error.
