Re: Compiling ROOT "test" programs on Linux

Hi Andre - I guess you need to use `-fno_rtti' flag when compiling your code. 
Search ROOT Web site for `rtti'.

Fons and  Rene: it looks like people are asking the same question again and 
again so it might make sense to fix section "Compiling and Linking with the 
ROOT libraries" (in http://root.cern.ch/root/Availability.html) to
specify all the necessary compiler flags in there(first of all - 
for Linux).
				What do you think? -Pasha
