Hi Thomas,
Assuming a file Thomas.C containing one or more functions that you usually
call via the interpreter, you can compile automatically this file and make a
shared lib with:
root > .L Thomas.C++
This will create a shared lib named Thomas_C.so
Next time you run, you can do
root > gSystem->Load("Thomas_C")
and then call your functions.
Note that in order to use this nice feature, your file Thomas.C must be a valid
C++
file. In particular, you must have all teh relevant include declarations at teh
beginning of the file.
It is a good practice to always specify the list of includes. When running
in interpreter mode via CINT, these include will be ignored if not relevant.
All that is explained in the Root Users Guide.
Note that if you load more than one shared lib, the load sequence must
correspond to the order of dependencies. If libB requires functions/classes of
libA,
you must load libA first.
