[ROOT] TMapFile: no memory mapped file capability available

Hallo,

I have a problem using TMapFile in my own program. When trying
to create a new MapFile I got the following messages:

Error in <TMapFile::TMapFile>: no memory mapped file capability available
Error in <TMapFile::TMapFile>: mapped file not in mmalloc format or
already open in RW mode by another process

On the root command line everything works fine, i.e. I can use the
producer and consumer examples given in the tutorials. Is there anything
that has to be enables explicitly ?

Thanks in adcance,
Volker Hejny
