Hi Mario,
instead of .L MyCode.C+ do
gSystem->CompileMacro("MyCode.C","",libMyCode"). The extension for a
shared lib of you current platform is added automatically. Have a look
at http://root.cern.ch/root/html/TSystem#TSystem:CompileMacro to see
some doc, and what else it can do (e.g. debug symbols etc).
Cheers, Axel.
