Hi Matt, With your static module, you will be able to run Root on your friend machine, but not able to execute CINT scripts that require access to the run time CINT include files and dlls, eg in your case when fitting an histogram/graph with an interpreted function. In order to interpret/compile these scripts, CINT will need access to a temp area (ef /tmp) to write some intermediate and temporary files. I am forwarding your point to Masa. It could be that only a very small subset of the CINT directories is required at run time. Rene Brun Matthew Bellis wrote: > > I'm confused.
