Thanks,

well I understand now why you pointed me to ACLiC and what it does, however it doesn't still give me the final solution which I'm after. Basically what I want to have is a binary called test which I can execute with some arguments. If I use ACLiC, then I will get libraries and can execute functions in CINT, but if I want to make it work straight from the commandline, then I do need the g++ commands.

Also what do I have to do to be able to just add #include "MyEvent.h" and then just use the object in any code segment? What kind of compilation does that have to be? Is ACLiC compiled .so file enough (if it's in LD_LIBRARY_PATH) or do I have to do something else?
