hello,

I have written this C++ code, later on i Loaded it with .L gambler.cpp and then excute it gambler(). the code worked fine but if i try to reload it again the complier gave this error:

Hi,
loading the same macro multiple times in the same ROOT session is fragile. Why do you need to load it multiple times? Note that you can execute gambler() multiple times after loading the macro once.

Cheers,

Hello eguirad,

i load it multiple times because sometimes i change something in the code, and i after i Load the updated code it does give me this error except if i quit root and start agian

Loading a macro, editing the code and loading it again is not supported except in the simplest cases, I’m afraid. @Axel might comment further when he’s back (next week).

As a slightly different workflow, you can simply re-execute the macro from the terminal with root -l -b -q macro.cpp, or work in a Jupyter notebook (e.g. with root --notebook).

Cheers,
Enrico
