PyRoot terminate execution after first C++ thrown exception

ROOT
11

Hi Werner,

I am glad you converged on a solution.
On the other hand if you are only interested to interactivity in PyROOT (i.e. no I/O), you do not even need dictionaries.
It is enough to load the shared library and inject the header in the interpreter.
For example:
MyClass.h

#ifndef __MyClass__
#define __MyClass__
#include <cstdio>

class MyClass{
public:
 void Greet();
};
#endif

MyClass.cpp

#include "myclass.h"
void MyClass::Greet(){printf("Hello!\n");}

Compilation line and python:

g++ -o libMyclass.so -shared -fPIC `root-config --libs --cflags` Myclass.cpp -I ./
python
>>> import ROOT
>>> ROOT.gSystem.Load('libMyClass.so')
0
>>> ROOT.gInterpreter.ProcessLine('#include "myClass.h"')
0L
>>> a=ROOT.MyClass()
>>> a.Greet()
Hello!

Cling is a much more powerful interpreter than the ROOT5 one, CINT, and reflection for interactivity is guaranteed even without dictionaries.

Cheers,
Danilo
