Re: Problem with statically-linked executable

Hi Tom,

   on SLC5 or other Linux version I've not (yet) seen the GetGroupInfo() warning. Do you see this when doing "make static" or when using special static options to link your app?

The Mac static version is currently broken as CINT is always dynamically loaded. We are working on a fix.

Cheers, Fons.
