Hi Ben, I have no problems in running your program as it is. I do not know on which system you run, or which version of ROOT you use. If you run on Linux, jus do: g++ -o ben ben.cxx -I$ROOTSYS/include `root-config --libs` ben This should produce the following output: ****************************************************************************** *Tree :tree : Testing still * *Entries : 150 : Total = 43417 bytes File Size = 24768 * * : : Tree compression factor = 2.43 * ****************************************************************************** *Br 0 :adc : adc[10][10]/F * *Entries : 150 : Total Size= 31662 bytes File Size = 13013 * *Baskets : 1 : Basket Size= 32000 bytes Compression= 2.43 * *............................................................................* Rene Brun Ben Morgan wrote: > > Thanks Rene, > Adding this line does allow compilation, but running the > program then results in a segmentation violation: > > *** Break *** segmentation violation > Abort (core dumped) > > Again, I'm running ROOT 3.01/06 under RH6.2.
