Quick work-around for you.
#include <iostream.h>
void tt() {
cout << "Ha Ha" << endl;
gROOT->Reset();
G__loadfile("iostream.h"); // use CINT API G__loadfile
cout << "Hi Hi" << endl;
}
#include does not work within a function. Cint provides G__loadfile() API
which does the same as #include.
But ROOT system has rules beyond raw cint. Fons, Do you recommend above
code or do you provide other means of doing this?
